To me this is evidence that Tony is trying to fix a problem with the Sink that shouldn't exist in the first place.
It would be interesting to rearrange his system and racking (removing that awful TV and centre speaker) to optimise it somewhat for stereo hifi use, and see what happened....
Perhaps Bub could scavenge up some Mana, I have some Sound Org tables, an Audiotech and some generic tripod stuff. Enough to make an alternative arrangement anyway.
