Damping the Foating CDP Laser-Track Tray

Reducing vibration at source is more effective than later addressing the same problem externally in my experience. The CDP/DVD player of medium quality (Denon 2910 in my case) again demonstrated this and I suggest that even those with significantly more expensive players may find it well worthwhile to check the following tweak (if they can gain access with the component cover off, tray out, power off and CD unit cover off or its equivalent for top-loaders).

It's simply that the fast-rotating drive with the imperfectly circular CD or DVD (even after beveling) generates so much vibration that it can overwhelm the insulation provided by the floating tray holding the track for the laser-reader to pass slowly across the radius of the disk. If you have ever moved your vehicle out of a parking spot at the same time as another moves in so that there is no absolute reference point, the mere thought of a simultaneous vibrating CD and laser-reader is an anathema. In the case of the Denon, I could not observe how effective the little rubber flanges (on which the laser-reader track floats) were as insulators so experimented with the sound outcome of placing different amounts of Rope Caulk and GB Duct Seal in different locations. It turned out there was an improvement in sound image definition and tone quality from placing a little piece of Rope Caulk on each corner. The reduction in blurring around each note made it possible to hear deeper into the music that then sounded more detailed and sophisticated.

Switching off the LED display and cleaning the laser-head with Isopropyl alcohol audibly improved clarity and tone. Using a color-marker on the laser floating tray over-sharpened musical dynamics to discord while black rendered the sound flat and two-dimensional. Apple-green and orange work well in the CD tray itself but purple creates discord.
