Default Irrational But Efficacious

I just bought a used copy of the Ayre CD Irrational But Efficacious and ran it on my Oppo BD205 at about 40% on the McIntosh MA8000. After, I played a jazz recording of my own making through my Teac X1000R. I have to say, it just sounded overall better.

What did this CD do to my amp? Well, whatever it is, it was a noticeable improvement. Not earth shattering, but just more clarity and coherence. Anyone use this CD?

I think I'll run it on the little bedroom system and the Woo Audio headamp as well.

I have it and used it. To me it did make an improvement. I run it maybe every month or so and always as soon as I get new stuff.

I have never done this but will keep my eyes out for a copy.

Iím sure this will raise many eye brows on the discussion board.

How often do you use the PAD CD in your system?

At least once monthly. I run the demag sweep daily before critical listening. Some folks use the disc to warm up their tubes with. My system is all tube but I donít run it that often.
I also highly recommend Jim Hagermanís frycorder2 and Frybaby2 be used every six months or so.
Iím sorry Iím not doing pics. Just too hamfisted mentally to figure it all out these days.
