turntable mat : boston mat, audioquest sorbogel ma

I m considering VPI HRX or Kuzma Reference. TQ

Still don't know what mat(s) you're talking about. The Boston Audio mat is pure graphite and quite hard; the AQ one is soft. In any event, why not wait until you get the turntable and try them both?

I can only speak from my own experience. I had replaced the stock mat (The Groove Isolater)on my Oracle some years back with an Audioquest sorbatane mat. I purchased a The Mystic Mat two months agoand it really opened up the extension on my analog front end. They say not to use it with a clamp unless the record slips while playing it and so i didn't clamp it. After a couple of days I said what the hell and clamped it and it added more bass to my Oracle.So you see you do what sounds good in Your system. Whomever you buy from see if they have a LOAN mat to try before you buy.

You have a gajillion options in the mat department, especially when you factor in the possibility of using combinations. I wouldn't even consider making a choice until you choose your TT and have it in your system, having assimilated its characteristics as supplied.

The Boston graphite and AQ sorbothane mats are very different not only to each other but compared to the stock platter/mat configurations designed into the TTs you're considering. Beyond that there are paper, cork acrylic, glass, ceramic, constrained-layer damped aluminum, steel, copper, Delrin, wool, foam, polymer options. And it only explodes from there when you consider stuff that is no longer in production but showing up on eBay and here. Certainly check out Herbie's Way Excellent series.

I have experience using both mats listed in your inquiry on three turntables: Oracle Delphi Mk II, Goldmund Studio, and Verdier La Platine. I found the Boston Audio mat to be superior in practically all respects. (As a caveat, I am not a particular fan of the Audioquest Sorbogel mat). Moreover, I found the biggest difference in quality of reproduction to be when they were used with the Verdier, followed by the Oracle, and then the Goldmund. Are there are any particular characteristics you wish discussed?
