turntable isolation feet

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.

Ah, the age old question: is it isolation or coupling? The big boys couple to the isolation stand with cones and also couple the isolation stand to the floor. To make things much more complicated, there is a hierarchy of cone materials, in order of desirability something along the lines of ceramics, steel, aluminum and brass. Generally speaking of course.

With a variety of turntables, I like also like the basic Mapleshade isolation system, but with the 4 Isoblocks replaced by 3 or 4 cryo'd mini-springs ("Baby Promethean Mini Isolators" from Machina Dynamica) supporting the thick piece of maple.

An occasional turntable/plinth design like B&O doesn't allow for easy positioning of footers against the turntable/plinth itself.

Many a turntable can be directly supported by the thick piece of maple, which in turn is directly supported by the cryo'd mini-springs.
This abbreviated approach is easy, low cost, and audibly beneficial.
