Rhirsch, I finally got my CoolCopy. My first unit was destroyed by UPS. This one was double boxed.
I do not find the CoolCopy discs that I have done thus far to be the equal of the RealityCheck copies. In both cases I have used RC black cd-rs. I also used the Raw Copy choice on the CoolCopy. I can hear a slight difference with a somewhat smoother sound with the CoolCopy and a somewhat more realistic sound with the RealityCheck unit. From AA, it is apparent that I am not alone in preferring the RealityCheck, but I am not done with my comparisons as yet. Other cleaners, Nespaing the originals, other discs, and better isolating the CoolCopy all need to be checked. I will try Symposium Roller Blocks as you suggest even though my previous experiences with them have not been satisfying. I never do anything without plugging it into my IsoClean ac filtering setup.
I also got my Nespa. As noted above, I need to assess its benefits in all of this.
