Just say no to glass. Less expensive and better sound management shelves are available. If you have glass, a very inexpensive tweak is to line the bottoms of the shelve surface with heavy felt, which is available in many colors, including black, the audiophile choice.
Do glass shelves affect sound Quality?
I have a TV cabinet with glass shelves that houses my hifi components. I'm wondering if the glass shelves could affect the sound quality of my components. I have a Classe pre/pro and 5 channel amp, Oppo 95 player and the Olive 04HD.
