I can't believe guys seriously recommend VTI racks, especially in a thread where OP has a CMS on order! The VTI racks are adequate for displaying a toy collection. Not for housing a high-end system. Definitely very bad for supporting a turntable. I've seen very nice tables struggle with feedback issues on a VTI and on my Lovan (which is very similar to VTI, but more rugged). Filling the legs with sand or shot actually makes everything worse, because the main problem with these racks is they lack rigidity (because they're cheap as hell). When I upgraded from the Lovan to a CMS Maxxum, all the feedback issues went away. ALL of them. It was orders of magnitude in difference.
I'm now putting together a 2nd system and have to use a nice turntable on the Lovan again (for the time being), and I hate it. I have an extra CMS platform I'm using which actually helps a lot, but the rack underneath really needs to be more rigid.
OP, your CMS Maxxum is one of the finest components money can buy - treat it as a major component, not an accessory. If your system is high-dollar, proudly run you gear on it! It's a statement piece that will make you smile every time you see and hear it. I know CM has had some production issues since they moved the factory last year. But it's worth the wait. I've had mine over 5 years now.
