My conditioner was on BDR Cones for years. Recently tried Nobsound springs. Well if you look at my system the conditioner is modded to the point its practically DIY. There's big stiff power cords coming in on three sides and the top. So even with springs it can't move around and so I wasn't hoping for much. But surprise, it was almost as good as everything else I've tried these under. Nobsound springs are so dirt cheap I would get a set if only to try them out.
Bonus, depending on weight you probably won't need all the springs. Drill some 1/4" holes into MDF or acrylic and use the springs you removed to make another set to use under something lighter.
