Mike New platter, Oyaide MJ-12 mat & STB-MS stabiliser arrive at Marco Towers...

Have you looked at mats like the Boston Audio Mat 2?

Marco,
I have not included a label recess into the Copper Composite Platter, for the simple reason that I do not consider that one should place records directly onto a hard surface, metal or otherwise. As I believe they require to be bedded down onto a soft plient surface for best sonic transfer. This implies a mat of some sort, many of which have allowance for the label or are soft enough to allow the label to depress the centre of the mat under the influence of the centre weight. Hopefully the thin OL mat when I eventually get mine to try!

I obviously can most certainly provide for a label recess for any one requiring it, at no extra cost, as it is merely a simple additional machining opperation.

Nope - got any links?

{Edit: just had look.... Interesting, although I think that the Mat 1 may be better suited to this particular application (being lighter and thinner): http://www.boston-audio.com/mat1.html }.

I'll look into it - cheers!

Marco.

Hi Mike,

Marco,
I have not included a label recess into the Copper Composite Platter, for the simple reason that I do not consider that one should place records directly onto a hard surface, metal or otherwise.

In theory, I agree.

However, that theory is blown out of the water when one listens to the Rubato copper mat on its own (which has a label recess), used on top of the stock Techie platter, which sounds superb (for reasons already explained in my final conclusions).

That's what I was trying to create when I asked you to bond a copper mat/plate to the platter you were making for me, so that I wouldn't need to use any further T/T mats on top....

Thing is, I didn't consider the aspect of having a label recess cut - my fault!

It's not a problem, though, as I *suspect* that the addition of an appropriate soft mat, as you describe, will provide further sonic benefits over and above allowing for a label recess

The thin rubber one I'm using at the moment is doing a good job, but I'm sure it could be bettered by something similar but of rather more novel design, such as I will be testing in due course.

I obviously can most certainly provide for a label recess for any one requiring it, at no extra cost, as it is merely a simple additional machining opperation.

It could be something to bear in mind in future. Let's see what results are obtained with the various 'top mats' that are going to be tested, and take it from there

Marco.

This is timely reading for me. I have ordered a copper mat from TTWeights in Canada (they make mats for the 1200 series and the SP-10s), and an Applied Fidelity bearing for my 1200, and am looking forward to doing some comparison listening. I currently have a Herbies Way Excellent mat on the platter, and will do some comparisons with and without the Herbies on the copper. The TTWeights is 1.86 kg, I believe, so a little over 4 lbs. The AF comes with an optional tall spindle to accommodate layered mats in this way.

Guys

Ummmmm any substance like vaseline etc will surely migrate across the surface of the platter (to the outside edges maybe ?) and into the electronics, through the holes ?

Dalek,
I think you are somewhat incorrect in your assumption here.
Vaseline or a good quality silicone grease is an excellent way to "connect the two surfaces". The grease forms an excellent vacuum seal between the two surfaces.
The effective atmospheric pressure (at sea level) is equivalent to about 14.7lbs/sq-inch; thus the effective pressure holding the two surfaces together is about 1,665lbs weight!! Properly applied the grease will not tend to migrate anywhere. It also takes up any deviation in flatness between the two surfaces.

I have use it with excellent results on my TT weights copper mat and alluminium Platter.
The problem is that it is damn difficult to remove the mat after a few months because of the amount of suction, as the two surfaces progressively bed down!!!!

Hey guys,have you ever thought about putting a record on from time to time?...they do sound better than mats

If it's cheap enough, the Spacemat below is excellent and really does properly support the record.......

Yesh, put on shome Shister Shledge, and Dishco Dave will shwivel his hipsh in his Chrishtmas shlipper-ettes and do wee shimmy-shingo for all hish fans (mostly over 90)....
