Best isolation cones

FWIW, I received my 4 BC Kones today and put them under my
EE Advant 8 tube pre that AC's had done little or nothing for.
Wham-Oh slamo, good jump on what was already a very good sound.
Esp. harmonics .

Has anyone tried SC-35 Oriton cones?

I use 4 Stillpoints Ultra Mini's under my Oppo 103 with great success. Absolutely love these feet! The Ultra Mini's replaced a set of 3 Alto Extremo Lyd 1's.

I use the Stein Music Super Naturals + (wood, ceramic and silver) and Super Naturals Signature ( wood, ceramis and gold). They are great sounding. I've been told the Black Ravioli are in some occasions better and lesser cost. I'll give them a try soon.

I've tried a number of 'em, including various Herbie's gizmos, BDR's, Tip Toes, large brass spikes, and more, including a few home made configurations and ball-bearing based design called Aurios.

I wish I could determine a clear winner. I cannot.

Sometimes all of this tweaking gets very tiring, and I long for the days when I'd turn on my stereo system, plop a record on the TT and simply enjoy the music. :)

Ahh, audiophilia….
