The AV & HIFI elements have their own mains spurs.
The Townshend speakers stands don't have as much effect as their racks, but they introduce an immediate set of benefits. They dampen down the vibrations that the speakers put back into the room through the floor, and the most noticeable sonic gain is in taking the bass out of the room and into the soundstage. Alas they are made to order, unlike the racks, so they both take a while and cost more than perhaps they ought to.
Macro shots as requested; sorry about the one I thought I'd rotated but haven't.
I'm not sure about a projector, but the stand was built with the view that it should accommodate a 60" screen. Eventually.
