IsoTek System Enhancer: Can it improve the sound?


I recently bought an IsoTek "Full System Enhancer and Rejuvenation Disc" Previously, I owned a Purist Audio Design "System Enhancer" for 15 years which a newly upgraded Ayre CX-7E mp. just spits out.

So I decided to replace the Purist Design device with the IsoTek. Before breaking the cellophane seal that will nullifies a full refund return to Music Direct, has any member used this product with success.?? Can it improve or enhance the sound of a system, especially one that has had some recent changes made. Thanx

The panel here does make interesting points;

what if, one's test disc is no longer rendered effective?
Is there such a thing as a test disc playing out (no pun), in terms of, not reviving our gear?

Keep me posted & Happy Listening!
Sunnyjim,

keep us posted as you break-in, burn-in your system with the Isotek disc(s). Happy Listening!
Sunnyjim-
