If you already have enough space for the turntable on your component rack, I would rather first try 3 (better than 4 for leveling) Stillpoints Ultra 5s (with cups) under the turntable, with the option of exchanging them for a full Stillpoints rack if they don't work well enough for you (no dealer would say no to that). I doubt you'll need more than the Ultra 5s even on a simple, solid wooden rack, they are better than the Stillpoint racks IMHO.
