A centre weight for your turntable, thoughts.

A lot has been written about this in the past (by me and by others). Whether to use a record puck (or weight) depends on the mat you are using and the balance of your system. In essence they will exaggerate the sound of the mat by increasing the coupling between the two. However, it is also worth noting that the weight of such pucks varies enormously. Another aspect is that a record weight/puck will increase the load that the bearing experiences - how much of an issue this is depends on the weight of the puck and the specific design and manufacture of the bearing.

Whilst I don't use it very often, my LP12 doesn't have any 'puc' with it.

Would it be wise to invest in one?

Linn specifically suggest that you not use a weight on their turntables. They say that under tests there was no improvement and that it would hinder the set up of the turntable.

So that'd be a no then... :)

I really do need to get the LP12 out of the loft and use it more often, only problem is that I have to wait until a time the Mrs isn't about :(

A puck no (and definitely not on suspended chassis deck), a record clamp maybe.

Depends on the mat and flatness of the record itself.

It all feels strange to me because I use a 'puc' with my Naim CD player, but the thought of using one on a record deck, not sure.

Although, I did see a pretty impressive (and probably stupidly expensive) record deck in the Absolute Sounds room at a Hifi show I attended where the demonstrator had a puc or magnet of some description.

All CD players use some sort of clamp to stop the disc from slipping. But you shouldn't draw any parallels between use of a puck on a CD player and a turntable - they are entirely different.

Linn don't recommend use of a weight for a number of reasons, not least because of the extra load it puts on the sprung suspension.

YNWaN
25-07-2013, 22:46
Clamps also have a potential issue. Although they weigh less than most pucks and therefore do not increase load on the main bearing, they do couple the record to the main bearing which, after the motor, is a significant source of low level noise.

I've used a fairly light homemade clamp for the last 25 years and find it does make a positive difference. I don't understand the liking people have for hugely heavy clamps, you're only trying to couple/damp a few grams of record, after all.

Right, so fundamentally, what is the difference between a puc on a Turntable and a puc on a CD player then? (in as non-techie as you can please :))

A CD is not supported across the whole surface just at the centre. A CD spins very much quicker than a record and the speed of rotation varies as it plays (so groove velocity remains the same). If a CD player did not have some form of clamp the CD would slip on the centre spindle and would not work at all. The clamp may be a little magnetic puck or if may be more like a traditional clamp and part of the tray loading mechanism. All CD players have some form of disc clamping device.

A record spins very much slower and is supported over a very much greater surface area. In addition, the speed of rotation remains constant. As a result a clamp is not inherently required to stop the record from slipping. If a clamp is used it behaves in a very different way to that of a CD player because the stylus physically tracks the record whereas a laser reads a CD in a non-contact manner. With LP playback the record, mat, platter, chassis, arm, cartridge and clamp are all physically linked together. For example, how tightly the record is clamped to the mat alters the level of damping seen by the record and this impacts directly on the sound. With a CD it is either slipping or it is not, if the clamping action is sufficient to stop the CD slipping then that is all there is to it - increasing the clamping force will not make it slip any less.

Wow thanks Mark, that's a comprehensive answer and one I think I even understand a little, thanks :)

It depends on the turntable but fixed (non-suspended) decks seem to respond well to weights whereas clamps are better for suspended ones - in general. The main bearing has to be up to the job and I would not advocate, say, a heavy weight with the standard Technics bearing.

I've had good results with the Bruil weight and Michell clamp in the past. My weight of choice right now is the (silly expensive) Stillpoints LP. It imparts a sense of solidity and structural depth that is a little better than the Bruil, together with great space around voices and instruments.

Hi guys
Thank you to all who took part in the poll.
This afternoon I decided to undertake a comparison test for myself. Using the same track from a well recorded, half speed mastered Pink Floyd album and after making sure that the turntable, arm and cartridge were absolutely set-up correctly. I started listening to the song, first with a 465gm weight and then again without the weight. I did this 3 times and formed a conclusion. To make sure that I was not trying to convince myself that I was not trying to get a preconceived result, I asked one of my sons to do the test without prompting from me. The exact same test was also done with my wife, who reluctantly agreed and believe me she's not a HiFi fan and has never used my system in over 35yrs of marriage but to shut me up she agreed.
The conclusion was interesting in that all three of us agreed. The result: THERE WAS NO DIFFERENCE. The weight made no difference to the sound whatsoever.
I am a bit of a perfectionist when it comes to my HiFi. I have spent the last three weeks fiddling with the VTA of my new arm and after quite a bit of trial and error and a lot of faff it all came together. I therefore believe that my test has credence

Ohh, absolutely YES.

Mats tried on the Technics: felt (UGH!). Ringmat Aniversary(don't start me on this piece of card). Technics Rubber(Dull). Inspire Foamex(kills dynamics, surprise as this was supposed to be close to Acromat). Finally Inspire Acri-Mat Deluxe. I like, dynamics very good.

They make that much difference Clive? I know that the felt mat on my LP12 was better than the standard LP12 matt but didn't realise there was that much of a difference out there!

Yes, I also think mats can make a significant difference. Not long ago I demonstrated a couple of mats to my friend Andrew - he was shocked how obvious the differences were (both mats were the same thickness so no VTA changes needed).

I'm honestly surprised you could not hear a difference when adding a record weight though.

I think the answer to that is simple. If you have a mat that works properly on your TT and records sit on it perfectly i.e. in close contact, the weight then becomes superfluous.

Hi, I find that both weights and clamps only have an effect on naked platters to help with slipping , I have never come across a weight or clamp capable of flattening a warped 180 g record (theses are the only warped records I seem to encounter) some weights do look nice though:)

Oldpinkman
31-07-2013, 13:17
I like your approach Clive. If you can't hear a difference, there is no difference to hear. So no need to fiddle about with blind tests

Mats will of course make a difference. All that energy in the record caused by rubbing a stylus in it has to go somewhere and the mat is the first place it goes. How easily it gets there (impedance match) and what happens to it when its there (absorbed, transmitted, dispersed) and how evenly across the frequency spectrum affect the sound. The Funk Achromat works by being a close impedance match to vinyl, and dispersing the energy evenly with its little bubbles. I have heard people say they don't like how it sounds, but never that they can't hear any difference. I could hear a difference on the PT - not light and day, but definitely improved detail - and the PT platter is already a very similar impedance match, and the bearing / subchassis do a very similar dispersal job, but there was a further (small) improvement with the Achromat. It will be essential to the new platter I am twisting Arthurs arm to make for me!

I guess all these things depend on how good the rest of your system is - but you should be able to hear the difference between mats on almost anything.

I think clamps can have an effect - but more so on soft rubbery type of mats. But I suspect there is also an element of wishful thinking from those who claim much of them. It is only improving the contact and on a good mat that probably has only a small effect.

Certainly, unlike designer mains cables, I can get my head round why they might work, and I seem to recall when fiddling about years ago, that I found some effects.

When music is playing, place your fingers gently against the side of a speaker cabinet - then press them firmly against the cabinet - can you discern a difference?

Thank you Richard. I think you may have it right on the head when you say "Clamps may make a difference on soft rubber mats". As I finally found the mat I liked is a hard acrylic it would explain the lack of difference that I have experienced.

I would like to try a Funk Acromat but the faff of spending £75 and then sending it back if I find no advantage is not something I feel like doing right now. I do need to compare it with my Acri-Mat and may get around to it in the future.

Not in my experience. I have experimented with a large number of different mats and adding a weight (or clamp) made a difference on all of them. However, whether that difference was for the better is another matter.

:lol: I can figure why - but I've been bullshitted by the old goat before, and know how to make up my own mind. If I heard a difference my views would be different. Arthur making one will have about as much impact on me as the £1700 speaker leads he is trying to peddle, or the interconnect with a bloody great arrow on it that I found at the factory. I am likely to take the piss until I hear it work.

As I noted - clamps at least make sense to me. I had one. Arthur has made one. I haven't tried weights because I have suspended decks. They can only really do 2 things. improve contact with the matt or resonate on their own and add a further colouration. Contact with the mat - on a hard mat is usually pretty sound. I guess the other thing they can do is stop a record slipping, but mine don't.(well weights can also grind a bearing to dust, or add to rumble)

You may have heard me moan about Colloms and the slowing under load, but we also had a fuss about acrylic platters not "gripping". I still have a white tippex mark on the side of my PT platter, and the side of a Marianne Faithfull LP I played 25 times consecutively. The 2 white marks remained perfectly aligned throughout. And this was an LP which didn't have a snug fit to the spindle. Katie Melua has a very tight hole. :stalks:No, let me rephrase that, my "Secret Symphony" LP is a very snug fit on the spindle,

Of course this creates another area of variability. If you don't push the record down hard onto the mat or platter, it can float in the air effectively and not only screw the VTA but any physics trying to cope with the energy noise from the stylus.:doh:

I've tried clamps and weights on and off over the last 40+ years. Over that period, I have had all sorts of mats, TTs with and without suspension. Never once have I noticed any improvement or even difference in the sound.

Recently I tried the Mitchell clamp on my present deck. This is a solid, non suspended deck with a vinyl platter. No difference at all. To be honest, I'm always much too busy listening to what the musicians are doing to be bothered with fiddling about.

Seems like another ploy to get at my hard earned.

Oldpinkman
31-07-2013, 17:55
We all hear what we hear Gordon, so YOU of course are right. However, I am sure I started fiddling about with this all those years ago because of the Oracle, which of course started the fun, and to which a clamp was integral because of the platter shape. I had a piece machined to fit under the LP label to use with a clamp too, but in the end I gave them up, which means any difference I heard either was a worsening of the sound, or was too tiny to fiddle about with. Comes back to a very very early vintage OPM thread about differences that matter as opposed to those you can maybe hear as a party piece to show off. :)

Ah yes acrimat. They were naughty little tinkers selling achromat rip-offs, and Arthur gave them a heavy shot of patent protection. What you've got is a thin PT platter. It's a great impedance match - it effectively makes the record much thicker. The PT platter effectively makes a VERY thick record. The theory has it the energy is transferred into the platter, through the very high quality bearing into a "lossy" sub-chassis which dissipates it to air. The sub-chassis is made from aerolam - like corrugated cardboard but aluminium instead. Very dead, very light. Its also cut to a shape which avoids parallel edges and so standing waves. Trouble is, if we assume the energy has transferred smoothly and evenly into your mat, where is it going after that. In a standard techie into a thin ringing aluminium platter on a solid deck.

The achromat is more of a foam material. Still a close enough impedance match to be a thick record. But filled with little bubbles which effectively do some of the job of the PT platter (actually in some ways do it much better). Have you not got a local dealer will lend you one or dem it in the shop. OK - its maybe better if stuck down (mine is stuck down) but it was apparant without sticking it down, and pretty obviously I havent tested whether sticking down or not makes a difference. AK insists, but as referred to before, he has learnt a few tricks, and that may be playing to the crowd :)

Richard I don't think the mat I use is a rip-off of the Acromat. We start with a cork base cut to sit within the edge of the Technics and is glued to the underside of a standard 3mm x 298mm Acrylic disc. Total thickness 5mm. A very different material(s) to the Acromat.

Sadly I do not have a local Funk stockist here in NW London so a demo would involve a 140 mile round trip to Analogue Seduction in Peterborough.

Oldpinkman
01-08-2013, 06:46
No your right. It's acrylic- the achromat is foam. Although the name is a bit cheeky. But the person selling them on ebay when I googled it previously sold a foam mat too, and incurred Arthurs solicitors wrath.

Shame about the mat. arthur needs more UK dealers. Maybe the LSD and new tonearms (and a focus on improving reliability, service backup, and availability) will help him grow his UK stockist base. As I noted - an acrylic acrimat is not the same thing at all as an achromat with bubbles because the energy has nowhere to go on a SL1210.

Just enjoy listening to the music anyway :cool:

Clive197
03-08-2013, 23:54
Right then. Achromat arrived this morning. Tested against Inspire Deluxe Acri-mat and Inspire Foamex mat. On inspection the Foamex and Achomat looked to be very similar, the centre label cutout on the Achromat was 10" and with both Inspire Mats the label cutout is 11".
First up was the Inspire DeLuxe Acri-mat. This sounded very smooth with no obvious vices (in fairness this is the mat that I' m used to). Next was the Inspire Foamex, a mat I have listened to quite extensively before but discarded with a preference for the DeLuxe Acri-mat. Base was immediately improved but the midrange seems a little muddled and the top end a little strident. Then came the Achromat, not only did this mat look remarkably similar to the Foamex but sounded very similar, not exactly the same, the base was also very good, excellent even,the mids were not quite as muddled but the top seemed a little more focused with no listening fatigue present. It's a close run thing between the DeLuxe Acri-mat and the Achromat. At this point I'm undecided which I prefer, neither are right or wrong just different. I think that if I had only had heard one of these mats I would have been quite happy, but HayHo.
Not surprised that Arthur is a little unhappy about the Foamex, they are very very similar.
To confuse things further I have just ordered a set of Isonoes which I think will be the final upgrade I'll do on the Techie. As I get no hum from the transformer and I now have the correct oil for the bearing, I see no reason to throw more money at it, instead I'll spend my money on more software i.e. music
:cool:

:cool:

Yup - the idea was Arthurs. Once you've had the idea its not hard to copy - the material is widely available. Without patents we wouldnt have innovation improving our lives. I'd missed that you had a Foamex already.

Wise decision about software. No point in having the worlds greatest turntable and nothing to play on it. :)

Clive197
04-08-2013, 10:05
Just to clarify, the sound difference between the Inspire Foamex and the Funk Achromat I suspect is due to size. The Foamex is designed to sit within the rim of the Technics platter while the Achromat is larger with a ridge cut to deal with the rim edge. As the Achromat supports the record over a wider area at both the inner and outer groove, the sound is improved, not chalk and cheese but enough to make a difference.
I think I may at some time have to retry the weight test using the Achromat. The Inspire DeLuxe Acri-mat is some 110gms heavier than the Achromat and may dampen the platter more, so in fairness back to the beginning, I will wait for the new feet to arrive first.

I had the new Civil Wars album delivered this morning and proceeded to play it; also with my album came two 10" EPs.

The main album is a 180g pressing and I played it as usual with my record clamp. When it came to playing the EPs I proceeded the same - but I immediately noted they didn't seem as well recorded as the main album. When I went to flip the EP I realised it was just standard thickness (not 180g) and as a result my clamp had not been clamping it (mine needs a thin shim for thinner records). I added the required shim so the record was clamped and was struck by the improvement!

So I have spent the last 20 mins swapping back and forth between the clamped and un-clamped state comparing various tracks on the album(s). Really, the difference is most pronounced - I can understand someone saying they prefer one over the other but to say there is no difference leaves me baffled.

Anyway, discussions that revolve around 'I hear it, well I don't' positions aren't likely to achieve any constructive resolution - but I thought I would throw the above in just to muddy the waters :).
------
Of course, it may all be specific to my mat and clamp - neither of which are commercially available. Or even to my system, which isn't exactly standard either. But I've tried clamps in friends systems and they all heard differences.

Are you able to describe the difference? Was the mid and top end less muddled or did the bass get deeper or thicker.

YNWaN
06-08-2013, 17:54
Was the mid and top end less muddled or did the bass get deeper or thicker.

I wouldn't say either of those aspects.

The most immediately obvious difference is that the focus of the individual instruments is significantly more pronounced. Without clamping the sound is superficially similar but more two dimensional and location of specific sounds within the soundstage is less pronounced than when clamped. The second most obvious difference is that the sound is superficially less bright and busy mixes sound almost 'simplified'. If your system is balanced against this aspects you may feel clamped gives a more 'shut in' and darker presentation. Indeed the whole presentation does move from the yang to the yin as they used to say in The Absolute Sound :)). In my system clamped sounds more focussed, better ambience retrieval, more solid (including the bass) and better controlled at the top end. Finally, I would say that when clamped the same record sounds as if it has been more closely miked!

I might have a play myself when I get back. I have none of my mains cable, directional cable, burn-in problems with this one. The grey cells are pretty addled now, but I am pretty sure I heard a difference, decided it was small, couldn't make up my mind which was better, and got tired of fannying around. The reason I now don't puck, is that I am laxy and like easy, and it was a small deal

Trying to look back through the haze, I am near certain I liked the benefit on a dished French LP of Sherezade I still love (Orchestra de la suisse normande playing it much too fast), but generally gave up on it is too much bother. I had a clamp and a small didgery doo under the record, which I got the boys to machine for me.

Will dig out a clamp when I get back.:)

YNWaN
06-08-2013, 18:28
I should say that I don't believe the purpose of a clamp is to stop the record slipping (which I've never seen any evidence of even on glass mats and those with very minimal support area) or to flatten warped or dished records (you need a screw down clamp for that, one that actively screws to the record spindle and you have to apply quite a lot of force.

The problem with most clamps (like the Michell) is that whilst they clamp very firmly to the record they don't actually press down much on the record unless you press down firmly whilst you tighten them up - if you use a softly sprung deck (like a Pink Triangle) it us very unlikely that you will press down very much at all. Many users basically place the clamp on and tighten it to the record spindle - which does little at all other than successfully couple the record to any noise from the bearing. The purpose of the clamp is simply to couple the record more tightly to the mat/platter (this may not necessarily be a good thing in every circumstance).

In many ways a weight is a better solution but can increase noise and wear in the bearing - they aren't suitable for low mass suspended decks either...

I think you are right about warped records although I don't believe even a screw down clamp will flatten any but the slightest of warps they just tend to move it, the main trouble I see with clamps and weights is that they only apply pressure to the centre therefore do not couple the playing area of a record at all to the platter:)

YNWaN
06-08-2013, 20:05
Well, I agree that the pressure is greater toward the centre than it is at the records edge. The mat I personally use only supports the record at the label area so the clamping force is actually in the right place for the mat - but in more usual circumstances you have a point.

Moving on, yesterday morning my Isonoes arrived and were fitted in a matter of a few minutes. On first listening I was very disappointed but on further listening thought that my records in fact sound very open with the music taking on an airy sound.

I decided to do a full blown test with my digital system against my analogue system and then once again with and without a weight.

My TT sits on a 10mm glass shelf which itself sits on sorbothene blobs attaching it to my stand. My digital system consisted of a quality CD transport and a Streamer which takes the music from a NAS drive in our upstairs office. All music is ripped using lossless flac. I used the Funk Mat for this test.

In direct A-B comparing I now find only a little difference between digital and analogue, with the latter being slightly warmer. I then did same test with a weight but found no difference with or without the weight.

The question I now ask myself is have I made my digital have an analogue sound (actually that was a goal) or have I made my analogue have a digital sound?

Clearly the Isonoes have made a huge difference over the stock feet, which in hindsight gave the sound a thick dense sound with a slight lack of clarity in the mids as well as a narrow soundstage.

The plot thickens, oh what a fun hobby we all have.

Latest and last.

I was not totally happy with the sound from my Technics. The Isonoes made a huge difference with both clarity and soundstage, the dense midrange had gone but the bass seemed like it had been thrown out as well.

I am lucky that 3 miles away I found an Isonoe stockist, so a quick visit and a little conversation later I walked out of the shop clutching a set of Isonoe Boots and a dent in my credit card to the amount of £34.95.

They have now been installed. I sat back.........WOW, now were cooking on gas. The Bass is back, the clarity and detail remains, I am truly a happy bunny. :lol::cool::)

I forgot to mention them (the boots, that is) ... :doh:
They do improve things further.
I bought a set when I bought the Isonoe Feet - got them whole lot from here - http://www.decks.co.uk/products/Deck_Accessories/Isonoe#.UgVkiW3hf4g

Did you go into their premises and get treated like this?

I'd feel cheated if they were courteous :eyebrows:

Sorry to disappoint, they were very courteous, considering I don't look at all like your average DJ, just an old nearly wrinkly audiophile.
