Can you objectively quantify the noise reduction? And which products?

@bemused , I have been a pretty hard core enthusiast in more than 20 yrs and have far more tweaks and power conditioning gear that could be considered as "normal". For example, I have more power conditioning gear on my regrigerator or my freezer than other entusiasts have in a large stereo system. So yes, it makes a huge difference. Actually, I have tweaked my systems so heavily that it is easier for me to hear upgrades I do on other ac lines, like the ones for refrigerator, freezer, ventilation etc. I don’t say that should be normal, but that is how it is in my house, even with dedicated lines, upgraded fuses in my meter board etc.
@justubes2, I find the Nordost QWave to be stronger than the Qv2, it is also supposed to work not only in lower bass region as the Qv2, but also upper bass. The QSine is kind of invisible, but just makes everything more transparent, also in higher frequencies, gives more air and bigger soundstage. It is easy also to see with video, the picture gets crystal clear. I find it to be better and more neutral than Qk1. It can remind a little of ADD Powr, but still they are different, hard to explain... IMO, both QWave and QSine do not limit dynamics at all. I have never tried Purons.
I too have most of power tweeks as yourself. For Nordost, 2x QX4 and also have several Addpowr symphony's.
Also found them of some high end cord are needed which gave very nice results and could not replace with cheaper cord.
The Ansuz active plug ins gave what you describe of the qsine and wave. I coyls use 2 at most and openess starts to thin out the mids. Are the new Nordost plug ins similar in effect?
I have have them scattered around, even on other power phase lines to good effect.
Recently added a good number of purons, also work well on lines elsewhere, no neccessarily at the plug to fridges, but i believe they had the same effect elsewhere, probably the same phase.
The purons are very different to the addpowrs, Ansuz plugins and found them more like the effect of the later HFC helix + plugins.
So was curious about the nordost. Do the nordost work more in the music room environment or anywhere around? I did not try the qv2.
justubes2, I see you have been playing with various plugs too:)
For Nordost QWave/QSine/Qv2/Qk1 they also are good on other lines, but I think they are products you typically prioritize to have on your stereo ac line. And here I prefer to have as many as possible of them. They do no harm, only good. Same with ADD Powr, especially the bigger units, but some of their plugs work well on other lines. And the same with Telos QNR and Macro N. For the Mini-Q I find it better to have them on other lines since they are not quite in the same league as their bigger brothers.
I have put ADD Powr Symphony Pros where I earlier had Nordost Qx2/Qx4 so the Qx2/Qx4 units I have are no primarily serving on other lines. I have them on both my refrigerator and freezer where they do a really good job:)
I am familiar with the HFC helix plugs. I have plenty of them and really love them, so what you say about Puron sounds very promising - and tempting! I found a US dealer who could deliver with Schuko plug. We´ll see...
