turntable isolation feet

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.
