Tellurium Q also has a demag disc very similar to the Isotek. Of course they claim theirs is better.

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 also have Isotek positioning disk which did not impress me. I used to have slight hiss noise out of tweeter and I had tried to reduce it with grounding block. But after trying Isotek CD enhancer, such hiss had been almost gone. Viola this disk saved me lot of money. Grounding blocks are also pretty expensive. |

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. |
