I note you mention a silicon mat as well as the acrylic platter mat . . . you are not using them together are you?
I think we're talking at cross-purposes again! They sell a silicone platter mat and an acrylic platter mat, both of which sit on top of the glass platter. Of these, I have only the silicone platter mat. I also have what they call the 'platter damping kit', which is a silicone disc (they supply 1mm- and 2mm-thick versions) that sits on top of the sub-platter, underneath the glass platter - intended to isolate the glass platter from vibrations coming from the motor through the plastic sub-platter. Between these two, there is an extra 5mm of height. However, the arm still looks dead horizontal. I'm not sure how to measure whether it needs any VTA adjustment - do you have any tips for determining that?

Yep I know the disc you mean now, I use tiny 2mm stand-offs made of the same material, I fashioned them myself but they do the same job.

As for VTA, you are using a 2mm sub-platter isolation disc and then the standard glass platter and then a 3mm silicon mat on top of that. You are currently using a Rega cartridge, so a 2mm shim will bring the arm close to standard Rega height. Most other cartridges seem to be another 2 (or 3mm) taller than Rega's.  A further 2mm shim will maintain the near statuesque as and when you change cartridge. Any variation in heights will be in the instructions with the cartridge alowing you to check theoretical VTA hight.

Acrylic platter mats in my experience work well, cost around £20-£30 and replace any mat you might be using.

VTA is a subject that can invoke feeling on here similar to mentioning 'cables' :shhh: . . . at the budget end of hifi I tend to agree, VTA, take it or leave it. However move on a bit in cartridge, and amp quality and the differences can be clearly heard in VTA and stylus pressure adjustments. So for the time being, stay with the standard, 'ask no question' figures.

When you move on, ask the VTA question again, be prepared for wildly differeing opinions, by that time you will have a better idea of 'what is what' anyway.  The real issue is the Rega arm, fine arm though it is, it is a pain to adjust VTA, so there exists the ostrich view; 'head in sand, VAT makes no differance' . . . you will see :bounce:  Most other quality arms have simple VTA adjustment . . . I wonder why that is :?

RE: Most effective upgrade for Rega RP3?

Has any of you with a Rega turntable tried this Rega tonearm spacer? And if so, do you recommend it? It's attractive because it offers various height adjustments at a cheap price, so I can play around a bit with arm height - and will be able to add a further 2mm when I replace the cartridge. It's made by Rega so assume it must be decent quality build, but if anyone has used it and can confirm whether or not it's a good solution to height adjustment. It says it's for 3-point mounting arms, which I think mine is (RB303).

The Rega one is pants! 

Do yourself a favour abd get the Michell Engineering one!

Whilst were on about VTA adjustments - I could never hear much with my Brio R but with the ST40 it really is apparent how these little adjustments change the sound!

 

Michell / Icon Audio / Kudos
