It is the problem the OP believes it to be. There isn't a technical problem to solve in the sense of introducing a modification that changes the physical sound coming out of the speakers unless the OPs hardware is heroically badly designed. However, there may be some that change the OPs perception of that sound if it hooks into what he sees as the problem. The suggestion of a cup and ball may or may not do this but the technicalities of what is or is not going on in terms of vibration propagating through the structure will be almost certainly irrelevant unless it hooks into something the OP sees as part of the problem.What kind of a problem is it? Aesthetic?
Or are you saying isolation isn't a factor for SS?
A turntable will/might benefit from being isolated from structural borne vibration and a cover might help with air borne.Why isolate ? , if you have got vibration problems surely its better to couple .
Does it just wobble and vibrate on top of that?i cut a synthetic bouncy ball in half. voila. looks spacey.
How do glass shelves resonate differently on each side?I had a dealer subcontract a bespoke custom made glass shelves stand to incorporate the same principles as a NAIM FRAIM
The tempered glass shelves resonate differently depending which side you tap on. The audible differences are there and not subtle for proper placement purposes
Then the glass shelf rests on machined ball bearings wherein the rack has a shallow “ dimple” depression in each corner for the ball bearing to actually sit in
From the NAIM FRAIM commentary on the NAIM website: https://www.naimaudio.com/product/fraim-0
“... Our Fraim equipment support system has been carefully designed to provide the perfect platform for Naim Audio electronics to shine. Each level is carefully isolated from the next using a cup-and-cone interface. An additional, double-layer base platform provides further isolation from resonance. A toughened glass sub-shelf rests on minimal-contact ball decouplers, providing even more isolation...”
Done properly ..... highly recommended.
What are these like?Naim sell “ball retainers “ (probably not the proper naim) to stop the shelf sliding.

Then if I put say 3 balls under that, resting on 3 nuts ?
How do I stop the 272 and glass sliding off the balls (kids around)?
Or the whole lot sliding off the rack?
Just to throw a spanner in the works, would it. Be possible to isolate the equipment from the shelf rather than the shelf from the rack?
