Do glass shelves affect sound Quality?

Agree with Onhwy61. I've always avoided glass but how much it deteriorates the sound would be hard to judge.

Thanks for your responses.

I inquired about Herbies Audio Lab and they suggest using a set of tenderfoot under each component plus a supersonic stabilizer on each component. Has anyone used these products and will they be effective on glass?

Herbie's stuff is very effective. Tenderfeet under my TT, various ISP-cups and blls under my amp & phono stage and a way excellent mat on my TT. I've been using Steve's isolation stuff for years.

MT10425, Thanks for your reply. I'll give the tenderfeet a try.

Does anyone have a response on the supersonic stabilizers?
