Tweaks for a top-loader?


I have the Electrocompaniet EMC-1UP. After seeing the spider clamp, I've become interested in the supposed improvements.

My question: Does anyone know of good tweaks for a top-loading CD player?

My hunch is that maybe the little puck that holds the CD onto the spindle now could be improved. But, it could come at a cost if the tweak is too heavy and impedes the spindle.

Any thoughts?

Go to Herbie's Audio lab. They have a real nice CD mat for top loaders. It works very well and sounds great too.
Sound Improvement Disc (SID) #15 is for top loaders. Damps the the disc and also prevents laser defractions. More focus and depth.
