I'm a computer scientist, and my job is to be skeptic and try to explain, prove, and experiment. I was indeed very skeptic on the fact that a sequence of bits may change the sound of the hi-end rigs. It does...
It's over an year that I have been using the Ayre and the IsoTek CDs. I have experimented on the following settings:You may like the resulting sound or not, but I have no doubt at this point that the sound changes. (I'm not connected to the CD companies.) I'm getting crazy since I cannot find an explanation (I'm not an EE). Before getting into the review, I want to talk of the implications.

Let me pose a question: if a sequence of bits can thus change the sound of your system and you listen twice the same track, are you listening exactly the same sound at this point? Is AB comparison still useful? I think so as first impression, but I also need to listen over long periods (days). Surely, using one of the two CDs before a listening session can help to level the initial setting.
Let's switch to the review. Each of the CDs has several tracks, but I found useful only one or two tracks each:Do you think your sound has become a bit dull and the soundstage is less open-air than usual? Run track #7 in the Ayre CD.
- Ayre: the seven track (5' full glide tone) is the one I'm running with some regularity.
- IsoTek: the second track (30' complex signals) can be run when you change configuration in your system, and the third track (5' rejuvenation) is the one I'm running with some regularity.
Instead, is today your sound a bit thin and bodyless, on the bright side? Run track #3 in the IsoTek CD.
This is it. I'm running the above tracks when I need them, so my regularity is not scheduled in advance. I know that this is a succint review, but these are the effects that I consistently noticed over an year. I could not find a useful application of the other tracks in my situation.

They also have the random noises and pops, but have no where near the impact.
It works. I've used it to burn in gear, and I use it if my system has been off for a long time.
