Two parameters of turntable design are wow and flutter and rumble.
IMO speed stabilty is the most inportant. It is very anoying. You want a table that can find the right speed and hold it there. If there is a speed variation you want a table that can detect and correct it.
Everything is a trade off. Most tt use belt drives and a massive platter. This uses inertia or what is called the flywheel effect. Inertia helps the platter maintin constant speed. However if it goes off speed it takes longer to get back. Then there is the Denon approach. Lightweght platter with direct drive and quartz locked speed sensor.This allows lightening fast speed corrections. However because the plater is so light thre is less inertia.
Rumble is ususlally the sound of the platter riding on the bearing. It can be really anoying in the bass frquencies. Most tt take the Linn approach by machining the bearing to the nth degree or having it rest on a substance like teflon. Air and magnetic bearings a re very effective.
Most tt makers choose high mass platter wit
