ALL direct-drive turntables have a "motor controller" of one form or another, built in to the servo circuit. I suppose it is possible that a DD turntable could benefit from a standard AC regenerator, like a PS Audio power source, but such a device is different in purpose from a dedicated tt motor controller. You can assume that the TT101 has such a one. For one thing, the TT101 has a DC motor; the PS inside the chassis converts AC into +/-12VDC and +5VDC outputs. The Denon has a 3-phase AC motor that is "controlled" by a feedback circuit. So, it's able to adjust its speed. (I don't know whether the DP45 has adjustable speed option on the control panel, but the more expensive models in that line-up do/did.)
Turnable database with TimeLine
Here is a database showing various turntables being tested for speed accuracy and speed consistency using the Sutherland TimeLine strobe device. Members are invited to add their own videos showing their turntables.
