What would give the best overall improvement

Last Leming.....look for Bear Paws to make your system sing better. They will give better bass, better mids, and better highs...for a mild outlay in cost. I think the world of the guys at Ginko, but their support thing for VPI is a step in the wrong direction.

Stringreen did I not recommend the aluminum over the acrylic platter?

Stringreen,
I have found something better than the eden sound products . I was running the terra cone footers with the brass adjusters on my SSC.

I bought Amcan footers (http://www.amcanaudio.com/)I put a large set on my Superscoutmaster along with the spiked adjusters and a set of medium without the spike adjusters on the motor, making both the TT and motor level in height. These blew away the terra cone footers, which I sold.

The Ancam product comes in stainless steel, brass and copper, all giving a different sound. I have no affiliation with the compny, just want to pass along a tip to fellow audiophiles.

I have been considering new "feet" but there are so many options. I think a better outlay of cash at this time might be to stabilize my rack.

It's a VTI modular system, not really high ended at all. I have about 6 stacked units now with the TT on top. While I get seemingly zero vibration through the rack, at least nothing I can readily notice, there is a slight oscillation of the rack if you push at the top. I think I want to try bracing the rack to the wall.

The best bet would be to buy a multi level rack, but due to space limitations it needs to be "tower" like in its modularity.
