We will see Monday when upgrades arrive UPS. My interest in 2 motors started last year when I heard a 30k Clearaudio turntable with 2 motors and it sounded spectactular. Buttery smooth with detail. That made an impression on me. He did not have a first rate system hooked to it and that made it all the more surreal. It also had the same tonearm and cartridge attached to it that I have! Benz L2 and Graham tonearm. I know his TT set up cost about 4 times as much as mine and cant compare apples to apples. One other reason I bought an extra motor with belts is uncertainty of AS being around in 5 years. On reason I went there was to buy a vintage Nak deck off his Craigslist ad. I had a chance to buy an extra arm for my Graham 2.2 but he wanted too much for it. Another reason was to see if my cartridge was the source of hum in my chain. He put my cartridge on spare wand and hooked it up to TT and it clearly was. Hum bothered me for over a year. After that I bought a cheap $39 shure and no hum. Then hum slowly set in again!!!!!!!! Found the culprit. Bedini clarifier was less than a foot away from cartridge. Live and learn. Actually the cheap cartridge sounded ok if you have a decent turntable. I did get the platter upgrade this summer with the 24 silencers and liked it. Tighter focusing with clarity.
