ISOTEK - Full System Enhancer CD

https://www.musicdirect.com/equipment/isotek-full-system-enhancer-burn-in-cd-version-2

I had tried several system cleaning CDs to have some modest effect.

But this one from Isotek give jaws dropping effect of cleaning soundstage with reducing hiss noise.

It is worth every penny.

I recommend other member to try this inexpensive tweak.

Get the Ayre CD instead. Same concept but more effective

  It would be interesting to compare those two system enhancer CDs.

Once my system got cleaned by Isotek, I am not sure Ayre will make further improvement or not.

Shout out for the original and still the best for speaker placement plus the burn in track works very well - XLO Test CD. I’ve only mentioned it like a hundred times.

I also have XLO burn in disk which did not impress me.

But Isotek did wonder to my system in cleaning the sound and reducing hiss noise.
