I myself along with Geary Koh, designer at Genesis and a winner of a loudspeaker of the year award, and Michael Percy thinks that the Isodamp is excellent stuff. In my own experience it is much superior to the rubber and cork as footers. I have both for someone near San Fran-Pacifica CA. if someone, at least as golden eared as myself with a system they believe is revealing enough to hear these kind of differences would like to try both as a tripod under a piece of their equipment I could let them try them so they can report back to this forum on the superiority of the EAR product, which is obvious. If they disagree with me than I will accept the derision of my detractors before committing seppuku. Tweaker

I had a career at EAR doing R&D work, and did many tests on C1002.
This material, when molded in the shape of an isolator (I believe
that they can be had at Michael Percy and Parts Connexion) can be
a very good isolator, and also has a highly damped resonance, unlike
many other materials that are out there. There is quite a lot of hype
and mis-information out there about isolation and damping, and still
a fair segment of the high end industry has not caught up with the
proper use of damping and isolation materials to improve sound.
Been using EAR products for 15 years.
C-1002 Black (there used to be a heavier rated blue) feet with CDPs and Phono Stages in metal chassis allow far more airy and revealing highs with just a slight dimunition of bass weight than metal cones or various species of wood blocks.
Amplifiers and pre-amplifiers in wooden chassis do better with Ebony feets so that's how I build mine.
In addition, all my builds have SD-40 Isolation for the magnetics. It outperforms various types of gasket material I've tried. Also superb for tonearm mounting boards as in the aluminum/SD-40/Walnut sandwich I made to mount a VPI JMW arm.
Completely disagree with the opinions of rubber and cork footers here; several different VPI models with brass cones sitting on 2" maple boards isolated by the rubber/cork pads on a single layer of wall mounted Baltic Birch sounds best to me.
The C-1002 is so highly damped that it is used in tanks to absorb the energy of exploding warheads among other military uses. Those guys in the military always seem to get the best stuff.
This stuff seems pretty strong. A Shore A durometer of 60 and tensile strength of 1574 psi.
I'm not surprised EAR Isodamp C-1002 material when used within a DIY audiophile footer design would sound better than rubber and cork pads primarily designed for industrial applications. Neoprene when used as a compliant decoupling material has an identifiably heavy-handed sonic signature that makes it unacceptable to my ear, and cork as a material only serves well as a spacer/standoff rather than an effective vibration control material for audio purposes, IME. Brute-force vibration control footers do well to avoid TT footfalls and CD skipping due to high energy level vibration prone environments, but I'm not impressed by mundane rubber and cork pads that actually affect various audiophile listening cues if used as an audiophile system tuning device, in addition to heavy-duty vibration dampening purposes. BTW, I'm currently compiling an affordable DIY vibration control footer recipe that might find benefit via the use of thin EAR Isodamp C-1002 material as one of several design options.
Duster, since there are no takers on my offer maybe you could consider a review of rubber cork vs EAR C-1002 like under a cd player or whatever. I feel that the EAR is way underappreciated as a tweak. Tweaker
How about a link to EAR products? Thanks.
Looks like we're pretty much on the same page. The rubber cork stuff sucks IME, IMHO, YMMV. But it really does suck. As stated before I use brass, wood and EAR C-1002 being the DIYer that I am. No end to the possibilities as to the vibration damping thing. EAR sounds much better than neoprene IMO but the neoprene was the best thing that I had found to quiet transformers. T

Rubber and cork... Meaning products like isol-pads? In your experience... What would be the "house sound" of rubber and cork when used under cdps, tube amps or speakers? Most interested in how they affect the TOP end and perhaps frequencies in the vocal range. How diff is the iso damp in comparison?
Any feedback from users of either product would be appreciated.
Thanks everyone.
The rubber cork pads are .29 each plus shipping.
No substitute for hearing them yourself. T
Neoprene is one of the oldest synthetic rubbers invented. It's still a good option for many ordinary applications, but not for audiophile use, IME.
