Soft squishy feet

I use the tenderfeet under a tube amp and I didn't hear a hint of difference in the sound. I will leave them of course for peace of mind, but I didn't hear a whole lot (if any difference) with them. Which may ultimately mean I need to further isolate.

Either way, shipping was fast, and overall great buying experience with Herbies.

Another vote for Steve Herbelin.

Jc51373, it may also mean that you amp is very well designed and does not need any further isolation. On some equipment, isolation seems to make a difference, on others there is no or negligible difference.

Pubul, good point...I want to believe that is true, but the self-destructing audiophile in me always has to tweak and upgrade, and play with things. : )

Tonight I added sorbothane sheets (cut into small squares) with adhesive backing to all the edges of the shelving on my salamander rack. Again, not much of a difference, just small from my first listening session. It did however do a great job of reducing vibration in the shelf though, I can feel the difference when music is playing.

Ok, so the sorbothane under everything is a no go...I don't know if I can completely describe what it did. Everything felt darker, too dark. Voices sounded more distant, and the sound stage definitely shrank some.

So I pulled it out from the corners of the shelf where my preamp resides and it sounded immediately a little bit more back to the way it was. I think you need to be careful with this sorbothane stuff, it can really make a significant sonic difference in a system. Good or bad.

I am curious now, I pull it all out if it will sound even better. Good way to find a balance potentially.
