turntable isolation feet


Which isolation feet work better? Rubber, metal cone, ...?
Does it depend upon turntable styles -- belt drive, direct drive, idler wheel?

I've found many isolation feet made of rubber or metal under $20 in eBay. What would be your best pick for turntable isolation feet for under $50?

Thanks in advance.

Turntable sitting on 3 feet made up of a brass plumbing bushing ring sitting on a granite sample block. 2 at the back, 1 at the front. You could also place 3 of the rings under each block. Almost free and very effective.

Can you be more specific regarding the brass bushing rings you used. I searched but everything looks like a pipe fitting...
Yeah... they are small brass compression rings. Ideal as they have low mass but are rigid and have relatively sharp edges. And they are brass which can sound good.
After 20+ years of trial and error with over 15 TTs owned I've come to the following conclusion, 3 adjustable brass cone footers sitting on top of a sandbox. I made my own sandbox for $22.00 and I currently use Dyton Audio adjustable brass cone footers that I bought on eBay for $35.00 including s/h.
I really Like the Isolation system from mapleshade. It uses 4 Iso blocks and a big 2" thick piece of maple and 3 brass footers. All for around $130. I love this under my REGA.
