Anyone have experience with the Nanotec Nespa?

John (Jfz), you volunteering to be the 'test subject'? Just kidding :)

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? :)

Last Sat. we treated a CD ( previously treated with RealDisc and ClearBit on the rim) with the Nespa. We then burned RCCD CD-R. Compared to a pre-Nespa version, the Nespa version was improved.

RCCD and Nespa work well together.

The question remains: how much improvement does EACH provide? (Nespa vs RC). I realize each can improve the other, but what if a person can only afford one. Has anyone done a direct comparison: just Nespa vs just RC?

OK, this took some time but I made 4 RCCD's: One of the black CDR's was Nespa'd before making the copy, one was never Nespa'd the 3rd was Nespa'd before and after and the 4th Nespa'd only after it was RealityChecked! Got this so far. The best sounding of all was the one that was Nespa'd after it was copied via the RealityCheck process. Nespaing (a new word now) a blank CDR before it was copied, did not have the openess and bass control that a copied RCCD/Nespa CD had. This was not subtle.
Still, as in my previous posts, I'm enjoying just zapping each CD with the Nespa unit and forgoing using the RCCD process, yes it's better doing all but the difference and time it takes is just not worth it, IMHO, yours may differ, or you have a lot of free time.
Enjoy, hope this has helped.
