From what I've read, something as soft as a Tenderfoot would tilt the sound far too downwards so maybe these would do something less offensive.@nonoise
I've replaced all the Tenderfeet in my system with other types of isolation/vibration devices. I can now hear that the Herbies dont articulate the midbass and they soften the bass attack.
I'm very impressed with the AV Roomservice EVP's under my preamp. The presentation is now neutral with tight bass. Like Ozzy, I'd like to find new footers for my 60lb. power conditioner.
