Can someone explain what audible benefits (or problems) if any a Michell Techno Weight would bring to a Rega RB330?
If there is chatter and instability in the bearings, they might be slightly more stable with a lower mass. However, the lower centre of mass would probably edge the arm away from dynamic balance, making it a little bottom heavy (centre of gravity lower than the pivot). This would make it track the downhill/back side of a warp a little better, but the uphill/front side of a warp slightly more heavily, and overall warp performance should be slightly worse as mass centre moves away from dynamic balance.
If the arm were a slightly top-heavy design like mine, lowering the mass would bring you closer to dynamic balance and better warp performance, which is why I put so much effort into lowering the centre of mass.
This is all theory, and I may have it wrong. The proof is in the pudding.
