Here is a list of things to look for:
1) a robust drive (apparently, can be idler, belt or direct, if done right).
2) absolutely *no* bearing play (slop) or flexibility between the platter and the cantilever of the cartridge
3) in support of #2, the plinth where the platter bearing is mounted will be the same part as where the tone arm is mounted, and will be a rigid, non-resonant material. Rigidity between the platter bearing (which supports the platter) and the base of the arm is paramount.
4) the platter will be rigid and non-resonant
5) the platter pad will be energy absorptive, and ideally the same durometer of hardness as vinyl so that it does not depress as the needle passes over it, but does absorb all frequencies originating on the surface of the vinyl.
6) suspension is optional, if not suspended accommodation for that will be needed in the equipment stand. If suspended, will be damped so that oscillations die quickly.
I've stayed out of tone arm mention for the most part but obviously the arm plays a huge role and is part of the bearing system between the platter bearing and the cartridge cantilever.
