Vibration Problem

I had great luck with Bright Star Air Mass 3 which can be had for about $100 new. The cheap equivalent is to sit your player on an innertube with just enough air to float the player, too much air raises the resonant frequency and reduces effectiveness. This solution works great for heavy footsteps, deep bass notes, etc. which can cause some players to mistrack momentarily. Mine just sounds smoother at loud volumes too. You could probably try the innertube on the cheap and go for the attractive implementation if you so desired.

How do you know you have a problem?

You can also go to your local specialty car audio center and see if they have Dynamat.

Dynamat is used in cars to remove unwanted vibrations and sound damping. a single sheet should be all you need. Stick it to the bottom of your cd player save for 4 small pieces to put up under the feet.

This might set you back about 10 bucks, and should reduce alot of the vibrations

Vibration problems I mention is simply skipping problems due to loud volumes with heavy bass. The sand bag or inner
tube theories are quite interesting but what I had in mind
was something with better appearance that could eliminate
vibrations at very loud volumes. Thanks again everyone.
