Anyone have experience with the Nanotec Nespa?

I can say that the cleaning of the original disc with either cleaner is essential to get the best sound. Also cleaning a blank BLACK CDR before duplicating is also a MUST to get the best possible sound. To not clean a blacn black CDR before copying is a no no. So first clean your original, and the blank CDR, Nespa the original, make the duplication, then Nespa the copy. A simple but well worth process for FULL enjoyment.

Steve, I, of course, have not tried the 8500, but I cannot agree with you about the benefits of Nespaing the original and the copy.

I actually preferred just Nespaing the RC copy. Nespaing the copy of the Nespaed original did not change my opinion. I am greatly relieved about not having to redo the 60 cds I have already made. All I have to do is Nespa them.

I also did CoolCopy versions of the Nespaed originals but have not yet listened to them.

Basically the Nespaing of the RC copies greatly enhances the realism of the sound stage and gives bass more impact. I can fell the change in my listen chairs vibration.

In passing I treated an sacd that already was improved by Nespaing for 60. I redid it as others have recommended for an additional 120 (I don't know what the unit is here, but I think it is seconds). This greatly improved the one sacd that I treated.

I really have no idea given what I have read about how the Nespa works why it has any effect on a cd-r with no metal layer. Have you asked Nespa about this?

Norm,
It's fine we don't agree on everything, we all hear different things and we all have different priorities what we listen for. There are several people who feel the RC duplicator is better than the Cool Copy but there MANY more who feel the CC is MUCH better than the RC, no matter, everyone agrees that duplicating is a big benefit.
As for Nesaping an original disc 1st, or just Nespaing the copy, I still hear an improvement doing both. Again, in my system, this always sounds better.
As for why the Nespa can make a CDR sound better, no, I've not asked Japan. Their is a big communication gap on most question I have asked, since I don't speak Japanese and no one at Nanotec speaks English. All I know is I've heard from over 100 customers that ALL agree, there is a positive improvement on ALL formats. Many customers report huge improvements on video discs, a cleaner picture, brighter colors....I've yet to try this since I don't watch any TV.
Keep the reports coming in, love to hear your further experiments.
Steve

I Nespaed another original and then copied it only to Nespa the copy. This was a Basie big band cd. This time the double Nespaed disc was better than where only the copy was Nespaed. How do I predict when double Nespaing will be better? I don't know, but I will probably not do the remainder of the 60 discs I have already copied.

Once again I used both the RealityCheck and the Cool Copy to make copies. These are the fifth and sixth discs where I used both, but only these two had been treated with the Nespa before copying. On both I prefer the RealityCheck as having a better leading edge and a better sense of the recording stage. I am selling my Cool Copy.

Tbg, I sold my RealityCheck dup, bought a CC dup but have found just Nespaing at the 30 then again at the 120, is all I need. Yes, a copy "can" sound better but then I don't have the time to LISTEN and isn't that what it's all about?
PS: Forgot, another must is cleaning your CD's with a good cleaner, I've tried most and have settled on this fluid made by the makers of the Nespa unit called Intron Protect #8500. It's quick and easy to put on and sounds better than the original fluid by Mr Louis, that 2 step process was a pain......
