Audio Horizons TP 2.0 Preamplifier

As Gammajo notes, safety is one very good reason to leave a cover on the preamp (or any electronic device with 120V running into it).
Joseph has told me about another benefit of keeping the cover on the unit: it helps the signal to noise by minimizing radiation distribution within the unit. If all other factors are held constant, the signal to noise will be better with the cover on the preamp.
The Audio Horizons chassis is quite rigid. I like, especially, the welds at the chassis corners which greatly enhance the rigidity. I have not sensed any audible vibration from the cover of my preamp. However, if that is a concern to you then do use some adhesive backed damping strips. Doing so can only enhance the benefits of the preamp.

I would like to know what brand of damping strips or material you folks suggest and where to get it. I would like to apply this damping material to the cover plate.

Thanks,

Bill

I'd suggest Dynamat. It's used for car audio installations to deaden door panels, rear panels, etc.

You can often find it on E-Bay.

Thanks Tvad. I will look into that tonight.

OK Rx8man, we are curious to hear what you have noticed sound wise as a benefit by replacing the metal top with acrylic.
