I might offer tickets if I see a bit more kit that I can't afford ;) but I'd feel a bit like a snake oil salesman selling something that ain't going to happen, no chance, you mark my words.
I'm happy to revisit this possibility after the event, if there's enough interest :lol: .

Have you finished burning yours in Martin ?

It's a bit summery for a fire to burn things in and the airing cupboard just doesn't get hot enough for spontaneous combustion. Whether Martin's ears have got used to any possible differences is another matter entirely though :)

I have just received some 0.5m and 1m 223.5 Connect Litz stereo interconnects, from Yannis, fitted with silver Eichmanns (aluminium body versions), which I'm trying as a possible replacement for my MG G2000HDs, currently in the position between my SUT and phono stage; the idea being having a complete loom of cables from Yannis, from my tonearm to phono stage, in the quest for optimum sonic synergy.

First impressions are quite superb, with the 223.5s having the beautifully wide-open infectious musicality and filigree detailing of the awesome 423.5 Phono Litz tonearm cable, currently in use on my Ortofon RS-212D tonearm, on the Techy. This cable deftly unlocks the densest of mixes and also lays bare the dynamics and realism of the finest recordings, thus making for a sonically beguiling cable partnership that doesn't break the bank.

I suspect that these babies could be keepers! Further thoughts in due course, once the cables have fully burnt in :cool:

Not quite to the same degree, as Mark's aren't solid-silver cables, and so have a different, but equally valid, style of sonic presentation. The 223.5s do the 'solid-silver cable thing' superbly well, but ensure that the end result isn't too 'hi-fi' sounding. They're a really lovely, natural sounding (and very musical), listen!

However, I do still prefer the G2000HDs between my preamp and power amp, and between my DAC and preamp. It's simply a synergy thing :)

The aluminium bodied Eichmanns provide better shielding from interference, in my experience, than the polymer versions, when used in analogue (turntable) applications. I use the polymer-bodied ones elsewhere in my system, to excellent effect.

Yannis is also sending me some of his 222-Connect Litz, to try, which is very similar in construction to the 223.5-Connect-Litz.

The difference is that the former uses larger, 22AWG conductors, and the assembly contains two hollow teflon air-tubes, twisted along with the Litz conductors (in order to add space with air dielectic and keep the capacitance low).

Details here: http://www.back-promo.co.uk/html/222connect-litz.html

It'll be interesting finding out if those can raise the bar even further.....! :)

I'm really not convinced they do provide better shielding Marco (and I have the aluminium bodies on my Eichmann plugs). Aluminium isn't great at shielding, they cover a very tiny part of the cable and they aren't connected to ground; they do look nice though :).

Indeed (and you may be right), but I guess that ANY metal will provide better shielding than plastic, or in this case polymer, which I suppose is why Eichmann make two different types of bodies for their plugs, for use in different applications, with both still being non-magnetic :)

Maybe not but if the configuration is using RCA connection for a 'balanced' input and the screen is taken to preamplifier earth via a flying lead then the body of the RCA plug could be connected to the negative wire of the cart. It could pick up hum or RFI if the field is strong enough. It may not be likely but it would be better practice to ensure the body is not conductive.

Perhaps, but in the case of the Eichmann the return 'grip' element is plastic (other than an embedded metal 'finger') and therefore the cover (metal or plastic) does not contact any conducting elements.

Well Andrew, I'm not sure what sort of 'evidence' you expect; you are happy to believe that connectors and cables make a difference (I'm not saying I disagree with this), but there is no hard (scientific) evidence that they do.

I have tried a number of RCA connectors with metal bodies and the plastic bodied Eichmann's (also some with no body) and none of them had any impact on shielding that I could discern. However, the construction of the cable used clearly did.

Perhaps, though inside the plug there is less than 10mm of cable unshielded (assuming the cable is shielded in the first place). Eichmann don't actually make any claims regarding shielding for the aluminium bodies. I've not come across any RCA plugs that have magnetic (ferrous) bodies; even cheap ones are made from aluminium alloy, plastic or brass.

Its very hard to solder the ground / return wire so its clear when the metal body is screwed on and hard to put heatshrink round it as well, very fiddly indeed.

Sure, Neal, but what I'm getting at is the superior ability of one shell type to shield against interference from RFI. Nothing else.

In that respect, it's simply a matter of comparing the effectiveness of both shell materials, in isolation: plastic vs. aluminium. The latter, by simply being metal, should be more effective.

RANT ON - DUCK FOR COVER

This discussion could go on for ever. No claim should be made unless it can be backed with unbiased, independent, statistically significant data to prove the claim. In fact I think we should make it a law on this forum. This would sure cut out some bullshit that seems to continually crop up month in and month out. Sure we wouldn't have anything to talk about but it may push people into actually trying to prove some of the shit that they type on this fourm. It really pisses my off when people (no i'm not having a go at anyone on the forum, just the community in general) make claims and expect others to follow like sheep. :steam:

Neal,

Why are ferrite rings (designed to reduce RFI), for example, not made of plastic? Are they grounded to anything, when simply slipped over a cable, in order to be effective?

Think about this in relation to where I'm coming from, regarding the RFI shielding properties of plastic vs. metal on the shells of Eichmann plugs.

Marco.

Reid Malenfant
30-08-2012, 21:11
Ferrite is ferromagnetic, aluminium isn't... Different kettle of fish entirely ;)

While you may notice that cores of ferrite are used in loudspeaker crossovers to generate a high inductance with a small winding, you'll find that aluminium is used to bolt ferrite transformers together in SMPS without affecting the self inductance of the transformer itself.

Why not extend the whole shell over the RCA plug, and better still make it from a non-resonant, non magnetic, RFI/EMI reducing material. This would surely offer the best cover possible??

Yeah perhaps, I'm only making conversation really, arguing for the sake of it. At worst, I don't think the aluminium shells do any harm and they do look nice - don't cost much either (I use them myself); they may provide a modicum of additional shielding too.

I've not read any claims by Eichmann regarding vibration (and, in truth, the weight difference between the aluminium and plastic shells is very small). Most of the design rational expressed by Eichmann seems to revolve around the concepts of electron flow, eddy-currents, defined conductor paths, conductor purity and impedance matching.

I didn't want to post this, as I can't find the source again, but I do recall reading that Eichmann produced the aluminium shells simply because they had a number of complaints that the plastic ones were too flimsy. Personally, I don't think they are (unless you are one of the sort that cycles equipment more frequently than underwear), but Eichmann still needs to run a business, so they produced the shell, and charge more for it. Given what they publish about the technical merits of the plastic plug, I would think they wouldn't hesitate to describe how the alu one is superior in some technical (i.e. shielding) way, particularly as they charge more. I doubt they'd leave it to mystery.

Marco
01-09-2012, 09:28
I asked Yannis what his views were on the subject, and this is what he had to say:


I read through the comments regarding the shells of the Eichmann bullet plugs and I understand that quite a few of those who contributed have not taken into account (or were aware) of the following facts:

Shielding against EMI/RFI works in three ways: by reflecting, by adsorbing and by conducting to the ground. The 3rd way is typically the one that carries the most weight in most situations but the other two should not be underestimated.

The aluminium shells by Eichmann are anodized. This is very important since anodizing is an oxidation process that changes some of the characteristics of aluminium (it is not simply a coating). Anodised aluminium IS NOT conductive (so it cannot be connected to the ground and act in the same way the cable shield does).

If the aluminium shell was not anodised it would have both reflecting and absorbing abilities and would act as a shield to a lesser degree even if not connected to the ground.

Other than unsupported claims by cables sellers who use these black anodized shells, I have never come across a valid point on how they can shield the connectors. On the other hand I don't think that anodised aluminium is transparent to the magnetic fields the same way the plastic body is; and if this is the case it does have a role as a shield.

I am not an expert on anodizing but as far as I am aware the process takes place on the surface of the metal (meaning that its core may preserve some of its initial characteristics and have a reflecting or absorbing ability that offers partial protection from some fields).


Interesting points about reflecting and absorbing with plug materials in relation to shielding against RFI/EMI, and in that respect, the role of anodising.

In any case, I'm 100% happy that the aluminium shells, from Eichmann, perform more optimally than the polymer variety, when used in applications where a little extra shielding is beneficial.

For me, basically, it's this:

Use the polymer-bodied plugs in high-level signal applications (such as between digital sources and amps, or preamps and power amps), and the anodised aluminium plugs in (more 'delicate') low-level signal applications, such as on tonearm cables, and anywhere else where the handling of low-level analogue signals is involved (and the necessity for a little extra shielding), which is exactly what I've done :)

Marco.

YNWaN
01-09-2012, 09:43
If I hadn't (rather neatly) applied heat-shrink to the join between my aluminium Eichmann plug covers and the cable, I would be tempted to see if I could hear any difference between them screwed on and removed.

I have specified anodised finishes before (and suffered many anodising trials and tribulations too). As stated above, it is a chemical process that alters the actual surface of the aluminium and renders it non-conductive. However, the process does not permeate very deeply and the majority of the metal remains as normal.

____________________

You know, if one really wanted the connector to be shielded, a copper tube that is electrically connected to the cable shield, or by flying lead to the pre-amp earth, would be very much more effective. I seem to recal reading about someone trying precisely this - can't remember where now - I seem to remember they were keen on the results though.

Looking at the WBT connectors, they have moved away from using metal in their plugs and the majority of the internal structure is now plastic on their premium designs.

Hi Mark,

I seem to recal reading about someone trying precisely this - can't remember where now - I seem to remember they were keen on the results though.


That seems to make sense, and if done properly, I can't see why it shouldn't work, and also be sonically beneficial.


Looking at the WBT connectors, they have moved away from using metal in their plugs and the majority of the internal structure is now plastic on their premium designs.

Indeed, and for very good reason. As such, the 0110 (ag or cu), plastic internal construction variety, perform to a higher and easily discernible sonic standard, than the 0102 (ag or cu), metal internal construction variety. I suspect that this is due primarily to the influence and/or absence of eddy currents.

As such, I now find that any plugs which have a high amount of metal in their overall construction sound notably inferior.

However, what's most interesting to me is why, to my ears, either the polymer or aluminium versions of the silver Eichmanns sound significantly superior to the WBT 0110ag, used on the same Mark Grant (G2000HD) interconnect cables - honestly the difference isn't subtle! :eek:

The WBTs and (aluminium) Eichmanns share the same shell material and absence of any conductive metals, yet sonically, perform rather differently. There must be something fairly significant going on with the way that the Eichmanns are wired/constructed, which is causing such a marked improvement in performance...

Any ideas as to what's going on? :)

I should add that this appears only to be the case in analogue applications. In digital ones (such as on digital coaxial cables), the opposite is true, where the WBT 0110ags, to my ears, are superior.

Marco.

It could be down to the method of cable to connector fixing or connector construction, rather than the amount of metal. John Coleman an old time forum visitor until he fell ill a while back did some extensive tests with connectors and fixing methods that were quite a surprise to me. I don't think he was however interested in publishing it online.

No doubt that's also a factor, however I've experimented enough now in this area to satisfy myself that there is definitely also something in the metal thing.

YNWaN

Not really.

Eddy currents can certainly be generated in aluminium and this is primarily the rational given by those manufacturers who have gone over to plastic (acrylic) cases for their electronics (such as DNM). Whether eddy currents can be generated by the typical music signal passing along an interconnect is another matter.

Both WBT and Eichmann state the alloy they use (silver or copper alloy), but neither state the specific mix of metals in the alloy and possibly this makes a difference. Also, although Eichmann's solution to attaching the ground to the socket is much simpler than the collet of WBT, it does actually make a tighter connection and over a smaller contact area - perhaps that makes a difference.

Not that I'm aware of, dude. Try the Eichamnns, you may prefer them to WBTs :)

I've not tried either yet. I was just looking at the cable on my PU7 and thought "Hmmm.. those phono plugs look a bit cack" and was wondering which to try!

Hi Mark,


Eddy currents can certainly be generated in aluminium and this is primarily the rational given by those manufacturers who have gone over to plastic (acrylic) cases for their electronics (such as DNM). Whether eddy currents can be generated by the typical music signal passing along an interconnect is another matter.


I definitely think there's something in it. I've heard a similar effect, although to a greater extent (in that case relating to ferrous vs. non-ferrous metals), with otherwise identical (Mana) equipment supports, the only difference being that one was made from magnetic metals (angle iron), and the other non-magnetic stainless steel.

'Night & day' just about described the difference between both, sonically!!

Perhaps that's one of the reasons why the polymer-bodied Eichmanns, to my ears, sound better than the aluminium-bodied WBTs, even those where the internal construction is plastic? The outer shell is still alluminium, and therefore subject to eddy currents. But then, the aluminium-bodied Eichmanns also sound better, to my ears, than ANY of the WBTs....


Both WBT and Eichmann state the alloy they use (silver or copper alloy), but neither state the specific mix of metals in the alloy and possibly this makes a difference. Also, although Eichmann's solution to attaching the ground to the socket is much simpler than the collet of WBT, it does actually make a tighter connection and over a smaller contact area - perhaps that makes a difference.

I think the last bit is likely to be the most influential.

Interesting that there has been no mention of the solder anywhere? I think it must play some part towards the sonic signature of any connector?

Whilst solder is important for bonding it should not be the main surface to surface contact medium. That's why I prefer surface mount components on a PCB instead of legged components that are separated from the copper on a PCB by a solder joint.

Wire-wrapping is where you have square-type connecting posts and a wire is wrapped around them. The square edges bite into the surface of the connecting wire forming an air-tight seal without the use of solder.

When alumminium is used in a cable it acts as an electrostatic shield. When you have a copper co-axial shield it acts as an RFI shield. Some cables have one or the other, or sometimes both.

First impressions are quite superb, with the 223.5s having the beautifully wide-open infectious musicality and filigree detailing of the awesome 423.5 Phono Litz tonearm cable, currently in use on my Ortofon RS-212D tonearm, on the Techy. This cable deftly unlocks the densest of mixes and also lays bare the dynamics and realism of the finest recordings, thus making for a sonically beguiling cable partnership that doesn't break the bank.

Well, after all that solder talk (I use Shark 5.5% silver solder, by the way), let's get back to Marco's post about the 223.5 ConnectLitz. I agree with everything he has said, the 223.5 grounded interconnects between my SUT and phono preamp sound similarly wide open and exactly in keeping with the wonderful 423.5 tonearm cable. They bring light to the proceedings, pulling detail from the mix and presenting it in a wide and deep soundstage.

I hopefully have a 223.5 balanced XLR version of the ConnectLitz arrived and waiting for me at work. That will complete the phono sequence, connecting my Whest phono stage to the Pass preamp. More as soon as I've got them going.

I assume this is because I can't get the window open far enough

Emailed Yannis and ordered a 223.5 Litz. Arrived Saturday.
Connected between Rega Isis and Naim 82 comparing to a TQ

Phono-Phono leads both using a Phono Din Adaptor
Couple of favourite tracks to try
Jeff Beck - Roy's Toy
Mavis Staples - Eyes on the prize
I thought there was more detail, more background information, not usually heard, better treble, especially on cymbals, a wider sound stage.
Broadly a small improvement
Sally preferred the TQ which I found surprising as her hearing is usually better than mine
So why only a small improvement ?
1. Brand spanking new lead not burned in. From memory the TQ was better than I'd heard it before so that is well burned in
2. Is the 82 limiting the signal ?..............

System synergy, perhaps, Mike?

No matter how much any of us here raves about any particular cable, there is no guarantee that anyone else will obtain the same results, in a totally different system. Quite simply, cables produced by ANY manufacturer can NEVER be a universal panacea.

All one can do is buy cables, report what one hears for the benefit of other forum members, and hope that if they also go for them, that what's described will also be what they experience, when using the same cables :)

One thing I would say is that, when assessing cables, it should really be done as a complete 'loom' from a single manufacturer, i.e. the whole system should be hooked up with the same cable, rather than mixing and matching with those from other manufacturers, as the effect of the new cable will be altered (and to an extent diluted) by the 'sonic signature' of the other cables, already being used.

Therefore, if you really want to hear what the 223.5 Connect Litz (or any other cable) can do, you need to introduce it as the analogue audio signal carrier throughout your system, not simply between your Isis and 82, which I know is easier said than done in a largely Naim system! ;)

Not necessarily. Let me explain:
A particular set of interconnects might be correctly balanced between say the output impedance of your preamp and the input impedance of your power amp. But that same set of interconnect might be in total imbalance between your CD player and your preamp.
One reason for that, as far as I have been able to deduct from my own cable designing days, is that with no fixed standard as far as output and input impedance is concerned, it is a trial and error game for the consumer as far as finding a suitable solution is concerned.

I'm happy enough with it to keep it for sure.
It still has to burn in and this is not this cable's permanent slot. I assume that will be somewhere between the record deck and amp - which needs some work, the absolute minimum being a SUT and Phono pre amp.
Wanted to try one and after my experience with TQ speaker cables against Naim I was prepared for a so so result.
'Happy enough' seems a good nutshell description

Marco
03-09-2012, 11:05
Absolutely, Stan, electrical compatibility is indeed another important variable to take into consideration.

All I can do is state from experience that, in general, I've always had better results using the same interconnect cables from source to power amp, than mixing and matching different types. Speaker cables are a different matter.

However, like anything in audio, there are very few hard and fast rules to universally follow - as ever, one must 'suck it and see' :)

Nice one. Experience so far definitely suggests that the 223.5 Connect Litz works best when used in the above scenario, particularly in conjunction with a 423.5 Phono Litz tonearm cable, between SUT and phono stage, which is precisely where I'm using it at the moment, to stunning sonic effect!

I really like the attention to detail Yannis has paid, in terms of earthing/grounding, by employing the use of flying leads to 'drain away' unwanted noise. I'm certain that this is a major reason why his cables sound so 'quiet', unfailingly musically involving, and thus allow the full dynamic range of the source components (and music) to be heard in all its glory.

Your new cable should really come alive when an SUT and new phono pre-amp are introduced into your system! :cool:

Marco
03-09-2012, 13:39
Hi Martin,

At the moment, it appears that the G2000HDs (fitted with silver Eichmanns) suit those parts of my system better, as the 223.5 Connect-Litz, in comparison, sounds just a little more 'restrained', and tonally, warmer than I'd like.

It could be a burn-in thing, though, so I haven't came to a final conclusion yet on the matter :)

Mark's coming on Wedsnesday to hard-wire a heavy-duty 'Furukawa beast' (for my copper amp), same as yours, to the mains junction box, powering my system. It'll do away with a 13A fuse and plug, and thus will hopefully help the amp to draw more current, when the music demands! :cool:

Hi Mike,


Sorry to be somewhat thick but how does getting rid of a plug,socket and fuse allow the amp to get more current?


Fuses in plugs are known, in that respect, to act as a 'bottleneck', and I have heard the effect that this has on audio equipment. However, if you want a more technical explanation, you'll have to consult one of our resident experts in that field. The other factor is that the new mains cable being installed has a larger size conductor core (5.27mm) than the one it's replacing, so that should also improve matters.

We, in the UK, are the only country in Europe to use fused mains plugs, yes undoubtedly for genuine safety reasons, with our type of electricity system, but IMHO, are somewhat OTT when you've ensured that there is sufficient protection (for your own personal circumstances) in place elsewhere. That, however, is not an invite for every Tom, Dick and harry to do the same!

*WARNING* FUSE REMOVAL IN PLUGS IS DONE AT YOUR OWN RISK - your OWN safety must come first!!!


plus if your amp is demanding more than the 13amp the fuse will allow what is protecting your equipment?


All my equipment is fused internally, at the correct rating, as specified by the manufacturer. The only thing potentially at risk in my set-up, is if the mains cable itself was to become damaged or catch fire, which is what the plug fuse is protecting. In my circumstances, having my system in a dedicated listening room, no kids, and where no-one uses the system other than me, where everything is regularly checked, that's very unlikely to happen :)

Marco.

Hi Mike

Your basic assumption is wrong. No amp is going to demand anything like 13A continuous. However, many big power amps can deliver some 60-100A peak on transients into the speakers, which translates into a serious peak current demand from your AC - for very short lengths of time. Anything that impedes that demand - thin or inductive cables, poor fuses - will limit the dynamic capability of the amplifier.

I think Martin's explanation sums things up pretty good as far as the reasoning behind removing as many bottlenecks in the chain' to ensure maximum current capability necessary for instant transient response etc, although it must be stressed that certain equipment will benefit more than others from this application etc.This is one of the many reasons why mains cables in particular [and speaker cables to a degree] make such a difference, however, as has already been explained, the people who go to these lengths are already well aware, and therefore accept that there is always an element of risk involved in the removal of extra safety aspects such as fuses in cabling etc, however, it must be understood and accepted that these people are striving to achieve a no compromise situation through out their audio replay chain as far as physically possible whilst still retaining the basic safety aspects of each individual piece of equipment in the chain i.e.; via the retention of the correct rating internal fuse etc.

It gives the noise the screen is stoping somewhere to go (simplistically).

I own a system largely powered by Naim (a bit modified in some cases) and have found subtle earthing changes to be clearly audible and often quite profound.

Ah. Thanks

The flying lead is for connecting the cable's screen to earth.
I'm surprised this feature isn't sold as it certainly improves the sound

Star earthing is a scheme which helps to avoid ground loops (hum) by having everything return to a central earthing point.
I was aware of hum caused by ground loops and assumed separate items of kit earthing would make it happen

Is the central earth a thing to look at for everyone or just Naim kit and similar ?

Star earthing is generally good practice for any kit - both internally and externally when earthing phono equipment.

You aren't going to make any internal earthing changes to a CD player - they are far too complex.

However, what is worth doing with Naim gear is to use a hydra mains lead. To be honest, I would sell your Kimber leads (and the PS Audio) and use the standard mains leads that Naim supply, made in to a hydra lead.

I found a massive improvement through using one of these. Better bass and soundstage. As good an improvment as fitting a good quality IEC. I do find the better top quality IECs quite a bit better than the basic wattgates.

I'm not sure I find the rhodium any better than the gold. It's just a different flavour. The rhodium on my power amp sounds too cold and clinical. The gold sounds great. The rhodium works ok on my pre-amp.

Don't bother Andre, I mean, the supply companies don't care how they twist and weld their supply cables together and what about the transformers down the road? No fancy wanky wire in them.

Just get your stock mains plugs (MK or Crabtree?), get the de-oxit or brasso on them to keep the brass nice and clean, plug in and out of the sockets every so often and maybe invest in a sparky to come over and test the integrity of your mains supply. Do all this WELL before investing hundreds on an expensive wet-dream mains lead and I doubt you'll go wrong :lol:

They're not a particularly "hot topic" for me either. Other than when I'm experimenting with new ones (which isn't very often), I rarely mention them.

The other thing which is relevant in your circumstances is that with Naim amps there's little to be gained by using anything else other than the supplied leads (mains or signal). When I had my old Naim system, the stock cables (and NACA5) always sounded best, for good reason, and so I never concerned myself with finding anything else 'better'.

With other equipment, however, it's a different ball game - particularly when used in revealing systems that highlight the effect of cable changes very clearly, and thus where there are significant sonic gains to be had! ;)

Thanks for the inference that my system is in sufficiently revealing - I don't know where that came from. As it happens, I don't use NacA5 or Naim interconnects to my power amps. My system satisfies me and has no difficulty in revealing the differences between cables, connectors etc. (very clearly).

Yes dude, today and tomorrow (up to lunch time tomorrow). 20 or so DIY nutters like Nick who build their own amps, dacs, pre-amps etc, etc. I say "nutters" in a nice way as we all got on well.

There were about 5 systems on show including Ali Tait's who I met for the first time last night, we had a few beers and a nice chat.

Mine and Nick's system was the Snells, the 401 and the wand, Nick's valve amp and pre-amp and various bits of wanky wire as some people like to call it! Very hard to get a good sound as the room is bad, at least we all got on and had a nice meeting.

Hi Lee, if your preamp has an earth connection then get a Yannis ConnectLitz with flying earths both ends and earth the DAC to it. Otherwise, use a separate earth wire to earth the DAC directly to mains or house earth. Watch out for any hum, which would indicate that the DAC is already earthed through its mains connection.

The amplifier does not have any earthing facility, its only the Dac. I think I will get just a straight forward interconnect without the earthing lead

Hi sorry for revival of old thread, but is Yannis still the best for the money?

Bought recently used SME IV which replaced (excellent) Audio Mods Classic II and am thinking about the new tonearm cable. The options I have (or considered) are budget < £250 (will be sending later SME IV for Ikeda re-wire):

- Audio Origami SOFC
- Yannis 428 with Eichmanns

I've read through almost all pages in this thread, unless I missed something, what is the opinion on stock 428 vs 428 with Eichmanns? I know there was a comparison between stock 423.5 and "pimped" version of it but don't recall comparison of 428.

I will have to use 90 degree DIN, I don't believe I could use straight one on Gyro SE.

Any feedback would be greatly appreciated.

Small update: I decided to order 428Phono Plus with KLEI Pure Harmony RCA plugs at 1.25m length.

There are some other variables that I need to test in isolation, all around the power cables and power block. Have Wireworld Stratus 7 UK version currently on my amp going to cheap-ish Tacima block.

Got another Stratus 7 (UK) going to Matrix 2 with Schuko (EU) connectors and that currently serves my phono preamp and Michell HR (power supply) with standard power cords. Also sourced Electra 7 with Schuko (EU) plug but out of the box (pouch) it was a bit "hollow" with the rest better (soundstage, lower frequencies and control). So I'm "burning it" in on my computer to see if all the good stuff will remain and if it will gain the smoothness, size and the body of Stratus 7. My friend is an authorised dealer of Wireworld and he suggested that I should be patient and give Electra few weeks of some juice flowing through it before making any judgement - I shall follow his advice.

First things first, power cables test and then, once received, 428Phono Plus. It will be a bit strange comparison as I don't have anything else than stock cable supplied with SME IV (my version is used and over 10 years old) but I will report back once I get my head/ears around all that.

Until then, I've got quite a few records to listen to from my latest eBay acquisitions and local records fair :) (Mostly classical music and some old ELP and Yes. My neighbours will be happy, at least it won't be just Frank Zappa and King Crimson next weekend)

Yannis makes some truly fantastic, competitively-priced hand-made cables, and in my experience has an intrinsic understanding of how cables 'work', in a hi-fi sense, like few others I know, but he does sometimes tend to 'disappear' and stop answering his emails, for no apparent reason, which as Rob's currently experiencing, is rather frustrating!

So come on, Yannis, surface from wherever you are and fulfil Rob's enquiries, as 'hiding', mate (presuming and hoping that you're well), is not good for your reputation!:wave: :ner:

Any one had any dealings or heard from Yannis lately by any chance ? :scratch:

Six months ago - doubt if that is much help though?

Yannis made me a din - xlr and a silver din - din interconnect recently.

Delivered within a fortnight. Incredible vfm.

Yes, I managed to hear from him some time back. He's done a number of superb cables for me over the years. Can highly recommend.
