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:
Marco.
Btw, Martin, did you see my post here: http://theartofsound.net/forum/showt...221#post358221
:)

Sorry to be somewhat thick but how does getting rid of a plug,socket and fuse allow the amp to get more current? plus if your amp is demanding more than the 13amp the fuse will allow what is protecting your equipment?
Sorry to be so thick
Mike
Ok, that's interesting. I now have the Yannis XLR ConnectLitz but I'm holding back as I've just got the SR7 up and running. I'll write about that in the appropriate place :)Quote:

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.Quote:

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!!!
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 :)Quote:

Hi MikeQuote:

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.
Indeed :)
Marco.
Hmm...Isn't that what the capacitance reservoir in ones amp is for?Quote:

Thanks for the answer, I still do not fully understand the logic, but this is not the thread for any further discussion, I will have to find out more.
Thanks again
Mike
Yes! (sort of)Quote:

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.Quote:

Yes, but the voltage rails will droop so it won't uphold peaks as well if it receives a lesser 'top-up' charge.Quote:

I only had the flying lead as I expect to need it in the final operating place
- plus it was free - nothing to do with *that* of course !
Some appliances are hard wired, but I think there is always a pull out fuse at the wallQuote:

No, not the same. What you are hearing are the effects of good screening. Remember my SUT earthing problem? Same effect.Quote:

You can do that with my power amps.Quote:

Like star earthing a technics 1210 PCB with internal regs for example :scratch:Quote:

Star earthing is generally good practice for any kit - both internally and externally when earthing phono equipment.
Another thing for to get me more music !Quote:

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 wouldn't go inside kit unless it was very easy and close to foolproofQuote:

Yep, that's the idea.Quote:

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.Quote:

Thanks chaps , I'm looking forward to trying this in my system :)
Yep, I like both the Furutech gold and rhodium plated plugs. Hi-Fi Tuning fuses make quite an improvement, too.
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.Quote:

The silver plated IeGO is very good and excellent value for money. Much better than Wattgates of the same price.
tbh im confused at all these cable details.. Whats the basic model before all the flash fittings are added, as i don't have the will to wade through this lot ?
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:
He will go wrong using a mains lead with MK or Crabtree plugs for a tonearm though Dave, as this is what you appear to be suggesting!
This is the basic version with the standard plugs Andre
