I use a Bell O' rack w/ glass shelves. I have not noticed any decrease in sound quality. It is heavy, probably not super "heavy" like some of the other racks out in the marketplace.
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.
