Using a flywheel to smooth out the drive is probably better, but not applicable in all cases. I remember seeing Micro Seiki using one of their massive tables as a flywheel to drive an identical table, using silk thread from the motor and between the tables. That was nearly 30 years ago, associated equipment then was not up to revealing how good the sound probably was. I use a single motor flywheel on my VPI Aries and it works very well. Whichever system is ultimately superior is not as important as how well the individual design has been executed.
Are more turntable motors better?
I did a quick search of the archives and couldn't find a thread about this, feel free to show me if I didn't look hard enough. Question is: are more motors better in a belt-driven table? Seems like pricier models are always more likely to have more motors, and manufacturers offer addtional motors as upgrades, but does it always result in improved sound? Theoretically, additional motors may tend to cancel out each others speed fluctuations, but overall noise may be higher. Thoughts?
