Is it best to isolate??

Isolating always leads to depression, or stems from it, for me..

Withe CDPs though I've found nearly anything you put under or on top of it, and what you place it onto does matter as changes will occur.

The 'flavor' of the change IMO comes from more than just those pods, cones, pucks, or balls in direct contact with the player. The rack or resting place plays as much a part too. Some simply buy platforms for players. Simple.

I like the herbie's Audio Labs wooden Ebony balls atop the iso cups so far as the best I've used. Jesus I am cheap come to think of it. $60-$75 for 3.

Like Stan said though, and I've heard from a LOT OF OTHER PEOPLE those roller cups are a viable solution.

Find those folks who allow a trial term and get startted trying 'em out.

Good luck.

Thanks for the tip on the granite.

All my equipment is removed from the speakers into an adjacent room. Meaning, lengthy speaker cables are used.

I've found that combinations of or with, wood and compliant materials keep the color in the music. Don't dry it out, over emphasize portions of it, nor make it too soft or listless sounding.

All spinning gear resides on one rack, while processors, preamp, and amps reside on another or on their own stands.

I like Mahogany & Ebony wood blocks as footer or as shelves/platforms. Also cups with large Ebony balls yield super results... in my own circumstance.

I prefer Bright Star Nodes over pods or other sorts of compliant soft rubbery junk.

Given all the comments from others here about isolating components, especially spinning ones, results will indeed vary, and therre's more than one way to achieve a better end.... otherwise everone would say the same thing wouldn't they?

... another option
