Isolation Platform - to be or not to be for CDP?

If I had a budget of $200.00 to isolate my CDP in an all wooden cabinet I would get a set of Aurios, although I don't know how they would fare once the rack was changed.

Instead of going into details, may I suggest a search of "Isolation Devices Binge" under the Tweaks/DIY forum at AA. Be prepared for some in depth reading & research.

I agree that Aurios would be a great help in improving the sound of your CDP.

Far better than Aurios, get a set of Symposium Roller Blocks with Grade 3 Tungsten Carbide Balls (or start with grade 25 TC balls). You can find them used on Audiogon for around $ 275.00 - $ 300.00.

You can use the Roller Blocks in conjunction with whatever platform you choose and the sonic improvement is terrific.

I've found the Gingko Mini clouds very effective under my cd player. The trick is to load the top of your player so the 3 blue balls support close to the 30 lbs they can handle....but for a very cheap tweak you can put superballs in vibrapods under the player. Place in a triangle under your player and place a sandbag on top of your player. Simple soup spoons held in place with modeling clay can hold marbles. This gives a cheap and dirty idea what 'better floaters like aurios' can do for your system....take your time, there is a lot at AA about this stuff. Have fun and Seasons' Best.

I think you should buy a Neuance shelf and support it on points on the corners. While I like Aurio 1.0 with tungsten carbide balls in many circumstances, on Neuance shelves they do nothing. Neither do RollerBalls with Grade 3 balls or anything else that I have tried. The Acapella bases are better than the Neuance but are too expensive.

Finite Elemente ceraballs directly under my CD Player made an obvious difference to me (~120). Right now I have them under my turntable with a 2" maple platform. I am getting another set eventually under my CDP.
