Anyone have experience with the Nanotec Nespa?

I own both, and I agree with Leec that the RealityCheck,if you want to extract the maximum from it, is a PITA to use. But it and George's fluids DO work, so I just suck it up and slave through the ritual. Really, it's not that much different than cleaning LPs. As for the Nespa, I own the Pro version, and it does work extremely well. I was at the same demo as Dlwask, and I was pretty stunned by the difference. I picked up my Nespa at CES, as I had ordered it a couple of months earlier. The main differences I noticed were a significant increase in resolution and a much more dimensional sound. It was not subtle, at least to these ears.

PureMusic:

I've only tried the Nespa on the CD-R AFTER burning it. Per Steve Klein, the distributor of the Nespa, I also Nespa the original prior to burning. I can't verify that this makes any significant difference, but judging from what it does to the CD-R, I'd venture that it improves the original CD as well--which would, in theory, improve the burning process, because the burner would have an easier time reading the original. Whew, now I'm totally confused. What was I saying? :)
