Cambridge Audio D500SE CD player

Trelja: Never mind then:-)

Trelja: Its mike again, I would of course be interested in how this inner tube works. That is if you try it, don't know what my wife would say about that one, she already thinks I'm nuts.

Trelja, I thought I'd chime in my two cents worth. I'm not sure to what degree my experience with my Cambridge cd4se is relevant to your d500se, but it might be. The sound improved noticeably on my player when I installed it on top of a sand box isolation platform and then put a one gallon baggie with three lbs. of sand on the top (transport side.) Also, a REALLY big improvement was manifest after reversing the plug polarity. After checking the chassis voltage with a multimeter I found it lower with the plug polarity reversed. Bass definition and clarity were especially improved. Keep us posted, Will.

Photon46's damping with sand on top of the CDP is also a good idea if you try the innertube support; you've isolated the unit from vibrations coming from its support, the bag on top mass damps the chasis vibrations. I'd hate to see what this all would look like if you did them all at once! Looking forward to hearing your results.

Just was no comparison against the BDR cones and sand bags - much more focus with none of the harshness the other tweaks brought out on my Alpha 8SE.
