Anyone have experience with the Nanotec Nespa?

Okay, Puremusic, I have done some comparisons that might interest you.

I used a cd by Nnenna Freelon called Live. She has a great voice and the backup is very driving. Also being live there is a clear sense of space. I had already made a RealityCheck cd-r using ClearDisc and ClearBit, the original fluids. I listened to the original which had been cleaned with these same fluids. I then Nespaed the original and listened to it. Then the RC cd-r, and finally that cd-r Nespaed.

The original is quite clean and pleasant. I arbitrarily will assign it a 1. I treated the original at the 60 setting, where 30, 60, and 120 are the choices. It was strikingly better, with more detail, sense of space, and improved dynamic. I would assign it a 1.5. I struggled with these numbers and do not really mean to imply that it was 50% better.
Next I listened to the old RC copy. Sometime I will make a Cool Copy cd-r as I have one now. Thus far I prefer the RealityCheck copies slightly.

The RealityCheck copy would get a 2 on my scale. It was strikingly more detailed than the Nespaed original and had greatly more detail and sparkle. It all so had the drive that I have always found with the RC process, if you stick with the original fluids. The bass was far superior than just Nespaing the original, and this disc has driving bass. There was a greater sense of soundstage depth.

Then the ultimate. I double treated the RC cd-r on the Nespa. The first was a run at 60 and then another at 120. My jaw dropped on hearing this. I was there. Her voice was so distinct and real. The soundstage was quite realistic with incredible detail and realism. I could hear those sitting near where she was singing. I would rate this as a 5, clearly greater than its parts.

My understanding of how the Nespa works would suggest it could be of no benefit to cd-rs as they have no metal layer, but it clearly works better on cd-rs. This is troublesome to me as I have been impressed with what the Nespa does for sacds, which of course, cannot be copied.

Tonight I will make another copy using the RealityCheck of the now Nespaed original. I will probably listen to it first and then Nespa the new copy. Again I am inclined to expect no improvement, but given my prior experience, I will not be at all surprised if further Nespaing adds further.

I know better than to generalize from a single disc, but that is the best I can do for now.

Norm (Tbg),

WOW, a score of 5 as compared to 1, 1.5 or 2. That is attention getting.Thanks for the info. Great work! The one thing that is consistent in your experiment as well as Leec's and Sksos' experiments is that Nespaing an RC cd-r is beneficial. Leec's results suggest that Nespaing a cd-r before duplication is detrimental. While Sksos Nespad the original CD before duplicating it, he did not give us a comparison between an RC copy of a Nespad CD and a Nespad RC copy of a Nespad CD. Your tonight's experiment should provide this missing piece. Please let us know your outcome.

Best Regards,

Sksos and Leec,

Have either of you compared the sonic improvements made by Intron #8500 Protect and the Reality Check's cleaning fluids PRIOR to duplication. Also, what is the sonic comparison between the DUPLICATES that were made using these two cleaners.

Best Regards,
John

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?
