Opposite effect with cardas/Ayre CD

It works for me. However, the first time I used it, I stayed in the room while it was doing it's thing and my gear did not sound right either, mainly because the disc messed with my hearing for a while. If you were in the room, this may have happened to you as well. A day later everything was fine. My suggestion to everyone is to stay out of the listening room when using any of these types of discs!!

I used the Purist Audio disc on one of my previous systems and afterwards the change was all for the worse. I got a refund for the disc from the dealer and never used one again.

No,Cyclonicman,i wasn't in the room during the sweep.
Just tried listening again to my system.Definite change for the worse.I wonder how long it will take take to regain the lost synergy.i just played Azymuth and noticed the Fender Rhodes is not 3D like it used to be but flat and little high frequency details are completely lost.Bass sounds like it is struggling and soundstage is shrunk.Still it is amazing that a cd can do things like that.I wonder if on certain days when we think that our system does not sound right (you know what i mean)is just the result of a last cd that we played the previous day somehow messing out with the system's static energy via its frequency modulations.
I wonder if MD will give refund for the CD.They will probably think that i made a copy of it.

Overhang, Sorry you are having such a bad experience with the Cardas Disc. I think you should call MD, they are pretty good. I purchased that Marigo CD mat a few years ago and it didn't work for my system. In fact, it made it sound like your description of the Cardas disc, except my system was okay as soon as I removed the Marigo disc. I called them and told them about my less than positive experience and they allowed me to return it for a full refund! Give them a call, I am sure they will oblige you.
