I found no such thread (except the dedicated turntable thread) but think it’s interesting, so here it is…
Take this: the setup of the owner of the fantastic label Fone. Did you ever see a stacked Tannoy setup, a Tannoy line source so to say (the same 2 are on the other side as well)?
Another interesting detail: he uses a turntable to drive the belt of another turntable.
Yes, he has two turntables with on board motor, so to isolate like with a separate motor, he uses one of them (with its on board motor) to drive the other. An expensive motor solution which might or might not create the best torque, but as he could afford a lot, it must makes some sense.
If ever there was a steampunk take on power amplifier design … we have a steampunk themed hotel here just a couple of blocks from the Magnificent Mile that contraption should be in the front window of. Very cool.
