I assume that Fig 1 is the "before"? Can we get a screenshot of the "after"?

I've been living with the P10 for 4 months now. I consider it indispensable. I hear all the attributes you mention, but the most noticeable thing for me was the dynamic impact. And I have 'good' power - the P10 says my wall supply has 2.2% THD.

As a point of comparison, I would offer that I have never heard a set of interconnects or speaker cables that make the same magnitude of impact (and I'm a cable 'believer').

"the opinion can be defended on technical grounds: low-pass filters limit how fast current can flow"


This is only true of *inductive* passive filtering. But not so with capacitive filtering, which is achieved with a parallel, not series connection and does not limit current flow, or the rise time for it.

Additionally, this does not have the ringing problem of the unfortunately ubiquitous conventional inductive technique. Also, there are inexpensive additional tricks for stripping RF garbage from the line. There are capacitance based power conditioners on the market. The regenerator types should more properly be compared to those if you want to talk about the effects on dynamics. Nor do they cost any voltage "off the top". Sorry, but on technical grounds, this review is incomplete.

(Good) regenerators do work well, but this is a very costly solution, where well designed passive types not using inductors can deliver excellent results at a fraction of the price. Plus, these do not have the current supply limitations of these bulky space consuming one-frequency (adjustable of not*) amplifiers, which is what these are after all, on electronic steroids. And the power supply to any piece of equipment is critical even if one is lucky enough to be located in "quiet valley with a little stream running through it, and your house is served by its own private transformer", even with great acoustics.

* Also useful as speed controls for turntables using AC synchronous motors, not mentioned in this article.

Can Stereophile provide before/after measurements of source, preamp, and amplifier behavior? I know they don't tell the whole story, but it would be extremely interesting to see if there are any changes in measured performance due to power conditioning.

They write, in the NuWave DSD's manual, that such devices may "'bleach' the sound and rob the music of life and dynamics."

Expensive snake oil.
