Topic: Denon DVD-2900 vibrates

Dump it!
I went through this problem with a Yamaha S1500. There is no fix. Some Denon and Yamaha models had this problem. The companies won't own up to it.
Get a Pioneer Elite. Rock solid steady universal transport. I believe Ayre uses them in their players.

If this is a known issue with the 2900 how come it was never addressed by Denon? I find it very hard to believe that the vibrations have no effect on the sound. I also find it hard to believe that a $1000 (in 2003) dvd player would vibrate at all!

Vibration doesn't destroy playback but I certainly wouldn't bet that it doesn't affect sound. I used to own a Denon DVD-2900 and it would vibrate with any disc that is drilled slightly eccentrically, it wasn't specific to format. I'd suggest checking your discs to see whether this is also true for you. There are cutting devices to correct discs if so.

If you want to hear whether there is any audible improvement with reducing vibrations at the disc/clamping mechanism interface, then check out a $3.95 CD mat bargain:

This has worked for me on a number of machines, even when there is no discernible vibration of a CD player, or CD transport, so should be interesting for you to hear what you think.

My 2900 usually only vibrates when reading a new disc. It does vibrate sometimes, but never during playback so it does not bother me. Most times it is inaudible during all playback.
