CD player vibration from CD's

I have been using three 1 inch strips of black plastic tape applied radially on CDs for some time. I suspect the tape reduces vibration of the CD whilst spinning. Of course there are a number of CD mats that address vibration, too.

Geoffkait: in my situation, I am applying the tape to correct (ie., offset) any *imbalances* a disc has, same way that a tire garage puts lead weights on the rim of a car wheel

I am guessing that imbalanced discs do not actually "vibrate", but rather that the entire disc drive/transport unit absorbs the forces generate with each revolution, and this then gets transmitted out to the entire chassis... I seem to feel a definite side-to-side motion in the vibration, not so much all around... but obviously it does eventually get mixed over

I have to wonder how all this shaking affects sound or video quality... given all the effort put in to "reducing and isolating vibrations" by manufacturers (incl. Oppo), wouldn't the severity of these vibrations make that look like a joke?

heck, a really "bad" disc even caused my wife's drink to shake after she had placed it ontop the Oppo the other day!.. she pointed it out to me, unprompted

still hoping to hear from other BDP-83/83E owners who can play a purposely imbalanced disc, and if they get chassis vibration even for a very small imbalance

thanks!

Ssouci,

I have the same problem with my Oppo player. My old sony has zero vibration with SACD's while the Oppo shakes. Did you ever find a solution? Does the unit need to be repaired? I'm wondering if the old sony maybe spins at a lower rpm, but I assume all SACD's require the same rpm, new or old player.
