Jerome, I can't speak for the Ayre cd, but I have used and heard with my own ears the benefits of the Isotek Full System Enhancer cd. Isotek are very open about how they devised the disc and it's purpose. I was amazed how was able to burn in my brand new Ayon CD-5s twice as fast using this cd! And it is invaluable to refresh my player after it's been sitting idle for a while. But you need not take my word for it, this cd has been widely reviewed.

From Isotek's website - "The Full System Enhancer CD is an intensive ‘workout’ for your audio system. The disc includes specially developed signals to help ‘run-in’ new equipment, as well as demagnetising existing hi-fi components and rejuvenating your entire system.

It is important to exercise an audio system across the full range of frequencies and amplitudes it may encounter in real life, and to this end the tones on this disc have been devised to cover the complete audio band from top to bottom, also ensuring that, for instance, high-amplitude signals are combined with high-speed ones.

In electronic terms, the required signals feature lots of high-speed activity coupled to some high-amplitude excursions. All of these signals have been produced according to strict mathematical criteria, so as to place the greatest stress on the important parts of a system – without, it is important to note, endangering any part of it."

In regard to cd mats, i'm more circumspect. My Ayon CD-5s uses a magnetic puck integrated into the heavy smoked acrylic lid which holds the cd firmly in place, whilst sealing out unwanted light and interference, so I think it depends on the player. I agree with a previous comment which suggested the Millenium mat would likely provide more benefit with less expensive transports. My 2 cents.
