I'm using Herbie's in my CDP and preamp. Most noticeable was the tighter bass. I noticed it immediately in my CD.

i have used E.A.T. dampers on tubes in a cd player. they have been in production for several years. they are aluminum on the ouside, with several teflon inserts placed in the inner grooves.
at first i thought they "warmed" up the sound, i.e., reduced harshness and smoothed out the sound. now, i am not sure. i recently compared a damped and undamped tube and did not hear much of a difference.
as for herbie's tube dampers, i thought they increased resolution and reduced warmth. i do like herbie's other products, such as anti-resonant devices.
"I used both rubber and silicone dampers on a CJ dac and pre.They both worked great though the silicone did melt a tiny bit."
This is true, some will melt and adhere to the tube. Be wary of the cheap orange dampers sold on ebay. As I said before, I use Herbie's and they are very well constructed.
