Tube dampers on your tube s in you CDP or DAC?

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

"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.
