TV/AV stands


I'm putting together a home theater and was wondering if it really makes a difference in the type of rack you put the TV and center speaker in as well as the other components such as amp, sound processor, dvd player, etc.?
Would glass shelving cause problems with vibrations from the speakers to the other components or disrupt the sound?
Any recommendations on racks for audio/video equipment?
Thanks.

I really like the "TV stand" I bought from Wood Technology. I have the one with the center channel speaker shelf and the quality/workmanship is first rate. Solid hard wood.

I custom build mine with Acrylic, which has a better resonation property than glass and is 8 times stronger. Look at the audio rack at www.trinicom.com/tate/acrylic.
If you want the glass look, acrylic has a clear presents that glass cannot duplicate. Hope this helps.
I've seen some acrylic stands but figured they would scratch pretty easy and start looking dull.
