OK, so I have to ask. Is this real, or is this a joke?

You going for a ride in a car missing one front wheel? Think it might be dangerous? But, you are an idiot for never trying it first.

"Your pathetic analogy is absurd and completely non pertinent to the topic … as is your presence on this forum. If you think your imagined “knowledge” trumps what I, and the other posters observe, you are delusional."

Actually, for most of us, the analogy is spot on.  We can't try everything that is claimed to 'work'--we have neither the time, nor the money. So some improvement that on the face of it seems absurd will have to wait for those modifications that seem to make sense.  I have $500-$2000 I want to use to improve my system, say. Should I squander it on stuff like this--how about new tubes? or a pre-amp?  or a pile of CDs?   I personally consider lots of things to be stupid and useless that I feel no need to experiment with.   Heroin, for example (Do I listen to those who scoff at me for not trying it?)  Sweat lodges.  Elixirs of all kinds. A new washing machine. And I ignore them despite the fact that their ads tell me this product will change my life.  I don't think any of us are really bothered by those who claim that of course, this hi-end product will only 'work' on systems much more expensive than ours, or only for those with the Golden Ear, or only for sound engineers.   As for those who claim that skeptics have no business commenting here, your religion must be pretty shaky to be challenged by an apostate or two.

" Actually, for most of us, the analogy is spot on."

Again, you are making an assumption.

This stuff may well work, but I have an ethical/moral objection to anyone trying to make a 1,000% or more profit so will not be buying it.

I've applied the nps-1260 to two runs of unbalanced interconnects, one run of speaker cables, and two power cords. It works. I'll be doing fuses next.

It's exasperating to hear comments from people on this forum who haven't tried a product but still think they can have a useful opinion about it. 

Back to what the nps did. No veils were lifted, I didn't see deeper into the music. None of the usual rave cliches apply. But it has been a clear incremental improvement and worth the price if you have that amount of fun money lying around. 

I had been using Perfect Path paste before this and thought highly of it. I have to say that what I'm hearing now with nps has been an improvement over the PP contact enhancer.

What I heard was cleaner bass with more natural overtones (my speakers go down to 37 Hz. I'm hearing a better 37). The sound stage is slightly expanded. The biggest difference I've found has to do with the mix within the sound stage. Music sounds less congealed, more open, with individual instruments positioned more clearly. I'm happier with that. 

I'd say it's a fool's errand to look for earth-shaking improvements from a single product. Products like that don't exist. But as obvious but incremental improvements go -- and that is all I look for – the nps was worth it.
