Which support for underneath CD player?

Official Hockey Pucks for a buck.

I found a Neuance to INCREDIBLY transform an older Rotel CDP by dramatically improving its coherence...so I even bought one for my new 44 lb EMC-1 mkII. The improvements here are indeed more subtle, but include a small further "tightening" of the presentation without the loss of bass articulation and timng so inherent in air bladders and "wobbly" supports. I understand rollerblocks also sound similarly tight and coherent.
Good luck.

Ernie - the rollerblocks were similar to using cones, just better, for me - but the Neuance was much better again. It is true some components benefit more than others - for example I find the excellent construction of Sonic Frontiers equipment means vibration isolation in the shelf is less important than with other gear.

Red,
Interesting sloppy experiment: wanted to install my Aleph P
inside my rack, drilling access holes appropriate for height cun Neuance, so robbed the Neuance from my emc-1 mkII
and slid it under the pre. Installed a Harm Tech AC ProII PC on the emc at the same time. Net result seems a bit rougher up top. Seems the loss of the Neuance is more important than the addition of a custom power cord.
Of course I'll know better after the second Neuance arrives (hurry up, Ken! ;o) and I can perform a proper trial of the two PCs. Ken's now making Alphas rated up to 35 lbs; Betas up to 65.
My comments re the rollerblocks are just repeated hearsay (as you might gather); those of the Neuance are empirical...
what a nice product, eh? Ern
Those

Plain old American Maple, 1/4" thick. You can purchase from any shop that caters to butchers. Works better than all the cones, iso bearings and Black Diamond shelving I have tried. I exlusivley use 1/4" Maple under everything. You should perhaps consider trying it as it is far less costly than some of the other options and I have found it to be far superior in sound quality. Now I will say that the Sony SCD-1 that owned at one time sounded best on the Maple supported by a tio of Walker Audio cones (the ultimate set). But everything else liked the plain Maple.
