Dpod4,
I am new to this forum and found all your impressive gears sitting on Quad's Bamboo? Or Sunoko Vent?
I also use Sunoko Vent and by design, if you use the brass rings supplied with the shelves (so the two columns go through this ring and connect the other shelves), the entire rack should show some kind of lateral movement since the columns are not rigidly attached to the shelves (but to the brass rings). Is it your also case? Or do you take the brass rings away? I asked since you are using the rack to house very heavy component, including the delicate turntables. Any idea if the lateral movement (well, you won't shake it when you are playing the TT) / this degree of flexibility affect your TT performance - or you think the TT performance are great now?
