The BA mat brought out a little more depth for me in my system but definitely pulled the dynamics back. Its always really interesting to see how mats/clamps interact with different setups, the last table I used it with it made all the difference in world. The highs cleaned up and bass was tighter and overall the whole mix felt like it just moved closer to me.
The old table Im talking about is the ever frustrating Wilson Benesch Full Circle with a ACT TWO arm. I never felt like I could get that arm dialed in given a lot of that had to do with the fact I just couldn't physically get the VTA low enough for any of my carts.
Of the 3 mats I've tried, ( the Boston Audio, Auditorium 23 and the stock mat) the Auditorium 23 is the winner. The stock mat would be my second choice
with the Boston coming in third. In my system, the Boston always brings a out bit of harshness that tends to fatigue over time. On a positive note, it makes
an excellent dust cover for the platter when the table is not in use.
I've only had 1 belt break in several months and that was of my own doing. Mike Pranka will send you more belts if you send him a SASE. Haven't tried
making my own belts yet, but I have all the materials on hand. A thicker poly thread would sure be more durable and easier to work with, so I'm interested
to see how this works out long term for Vortrex.
I don't use any clamps or weights with the Amadeus as they're definitely not recommended by the designer.
