I use the Origin Live dc motor and controller on a Oracle turntable. I find that the temp. of the room has an effect on the speed. If i let the room cool off or heat up the speed will change slightly, but it is audible. Letting the motor run for 15-30 min. prior to listening helps warm up the motor and oil in the turntable bearings. If i maintain the temp. in the room and i check the speed before every listening session i usually never have to adjust the speed. The Origin Live motor and controller is very accurate and the strobe will vary the slightest amount at the very begining and very end of the lp. The instructions for the Origin Live say to adjust the speed when the stylus is in the center of the lp , this gives almost perfect speed throughout the lp.
The largest improvement came from removing the Oracle motor and making a motor pod for the Origin Live motor and allowing the motor to sit on the turntable stand instead of the plinth or base. This removed all the vibrations that the motor generated and now my turntable is extemely quiet. To see if your motor is generating vibrations and transmitting it to the turnable put your ear against the plinth with the motor running and if you hear noise this may be heard during playback.
