Acrylic Platter sounds better?

Hi!

Does really acrylic platter sounds better than the glass? What is the reason? Could somebody give me a(n) (scientific) explanation? Does it worth the investment?
How about this:

Hi,
Acrylic platters can bring improvements to sound quality as they better match the resonance of the vinyl itself, but it's important that the replacement (a) has similar mass to prevent speed instability and (b) VTA is carefully adjusted after fitment if the height of the playing surface has changed. Also you'd normally use an acrylic platter without a mat so a well designed one will have a label recess.

Another choice would be to use the original platter with a Funk Firm Acromat mat, or replacement Achroplat platter, although the glass platter is actually a pretty good upgrade if you have a Rega with an MDF platter.

Regards,
JaS

Hi JaS!

I am a bit wiser now :)
On my Planar 3 I have the standard glass platter and standard mat. You say that the mass of the acrylic platter must be the same of the glass platter, that makes sense. But probably of the different density of the glass and the acrylic leads to a VTA problem and there is no VTA adjustment possibility on my Planar 3 + RB300...

How about the SRM-tech acrylic platter?

Many thanks

Hi,
I haven't used one so I can only go on their description. They claim their 'deluxe' version doesn't affect VTA if used without a mat (which is good), although the P3/Planar 3 and Planar 2 had different thickness glass platters so I don't know which they took the measurement from? Also I don't see any mention of the mass but it should be better than their somewhat lightweight 10mm version.

JaS

The sound from my P3 improved quite a bit with a acrylic platter. I recommend this:

A 2nd vote for Acrylteller, he makes all the German made platters, Scheu, Clearaudio, etc etc

How about your VTA now?

identical, they are the same height above the subplatter.

Are you using it with or without the mat?

I put 1mm rubber spacers (like it's used on the SRM/Tech platter), and use it without mat.
Recently I found that those spacers must be put with the utmost precision or the platter will wobble.

i run mine with no mat, which is the same height as my glass platter was with no mat.

Thanks
yes, works well with my kit. Note: I'm not using the felt with this piece in play.

I was also thinking of buying the SRM tech 20mm acrylic platter - for use on a Rega P2.

Can anyone tell me why you don't need to use a mat with acrylic platters?

Thanks!
