At the Rocky Mountain Audio Fest I heard the TW-Acustic Raven AC turntable with two tonearms: a Schroeder Reference with a ZYX UNIverse (copper) and a Dynavector 507MkII with a Dynavector XV-1s. I thought both tonearm/cartridge combinations were excellent. Which you would prefer would come down to individual preference. Of course, you have to remember that the 507 Mk II and the XV-1s are very synergistic.
