PS Audio Noise Harvester

Electroid,
You may be mis-interpreting my comments. The rolloff of high frequency is on the power line, not on the reproduction of the recording. Yes, I can easily believe that if the RFI is reduced on your power lines that this would translate to a more relaxed and extended high frequency presentation without any rolloff. The removal of noise on power deliver is frequently described as translating to a "blacker" background on the music, which would allow a better presentation of low level detail and of high frequencies.

Just want to give my experience with the noise harvester. I have had one in service for over a month. I honestly can't perceive an improvement or detriment from its use. Maybe my ears are shot. But what has fascinated me is the unpredictable behavior of the blue light. I have a dedicated music room with a dedicated circuit that includes three 15A wall outlets and an overhead light. Typically, but not always, the NH may not flash for the entire day until about 9 PM. After 9 PM it generally begins to flash, sometime once every few minutes while at other times a few flashes per second. I have also witnessed rapid flashing continuously for about 36 hours. Then again I have seen it remain silent for two days. No relationship to day of week. And I have deligently tried to correlate the flashing with operating in-house devices - but THERE IS NO CORELATION!. I have check the 3-5 times per second flashing at 3 AM when nothing (including the fridge, AC, and lights) were on. I tried to relate the flashing to rain, relative humidity, wind, temperature, etc., etc., ad infinitum, BUT NOTHING. Can someone please explain this behavior? As far as I'm concerned, at present the NH is nothing more than a noise sensor that presents curious patterns of external power line noise that I can't explain.

Anybody else experience this? Thanks.

Nano, seems like an expensive late night light show , I think i"ll pass 8^)...

I, too, was skeptical beyond belief regarding the PS Audio Noise Harvester. I read the AVS Forum threads, which actually added to my skepticism but also somehow managed to futher tweek my curiosity. I ended finding one here on Audiogon (thanks again, Audiogon, for always having ads for what I'm looking for!) for $75.00, new and in the box. I plugged it in to the same circuit as my system is on, which is a dedicated line from a second sub-panel, with hospital grade receptacles, and sat back to listen. The first thing I noticed is that it flashes like there is no tomorrow. Is my line that dirty, or is just designed to do that? I don't know, but I do know that definition and detail have been enhanced. There is better delineation of instruments, and a more projected midrange. Are the changes radical? Well, no, they're not, but they are there. Is it worth a hundred dollars? Perhaps not, but at $75.00 I don't feel as though I was taken.
