Jerry at 10Audio really liked the Amazon Referenz and Moerch DP-8. See his review at link.
It does seem that many table manufactures are getting away from vinyl and going to composite materials so that might be your next step. Having said that there are better arms then the Moerch so you might step up to a better arm on your Amazon and see what the results are before you sell it outright.
Thanks, sounds. I didn't even consider that... not sure why. Probably because I just love the unipivot sound. Brings great air to my Quad ESLs. But I know there are better arms. I should probably try a Schroder first since that's another arm Amazon likes with their tables. And the DP8, but it's a lot of money.
