Plexiglass as a top for a tube component? How could that be better than steel or even aluminum or copper for better heat dissipation or EMI/RFI isolation, aside from rigidity?
Amplifier Enclosure Resonance
If I tap the top/side cover on my Audio Research Reference 75 SE amp, it has quite a tinny ring to it. I'm thinking that can't be best for the sound. Does anyone know of a product that I could place on top to control that resonance? It would have to be three inches or under, wide, and somewhat heat resistant.
