Stereophile - MF Supercharger article-add 550W/ch.

Have you read this article in september issue of Stereophile?
It says that Supercharger pumps up your system to 550W/ch. and leaves "no sonic signature" - "Like a chameleon".

It works like this - simply connect Supercharger between your power (or integrated) amp and speakers.You only need a new set of very short speaker cables.You get 550 W/ch.,better dynamics and bass, and everything else is the same.
It is claimed that it only increases dynamics, and doesn't change "the sound" of your original amplifier.

Without questioning Stereophile's knowledge (it is my favorite magazine) i just find it hard to believe this.
My question - has anyone actually tried adding supercharger to the SET based system,2-20 Watts of primary amp. power?
And can any owner of such SET system say it didn't damage (a bit at least) the magic and "the sound" of SET tubes?
I am aware that in article Scott 299B(18 W/ch.) amp was connected with Supercharger.
I want to hear from owners of SET based systems who have tried this.Or from other people who have some opinion on this subject.I just find this hard to believe.

Atmasphere,

A good empiricist needs first assure an absence of artifacts in such a demonstration. The signal generator and transducer can be sources of spurious acoustics, especially with square waves. A fast scope can monitor a generator, but I don't know how to monitor a transducer to assure absence of artifacts.

DBphd - you have a really interesting background and it seems your discipline could really add alot to so much of what we discuss here.

If you ever get the chance to hear any atma-sphere amps you should.

You might be shocked to hear how different (and how utterly un-tube like) they sound compared to the Mac gear you are so intimate with.

I have to agree with Atma.Tubes do sound natural, and SS amps don't.I don't know how to explain it, but it is what i hear in a second.There are good SS amps, but they always (at least the ones i heard) lack timbre and natural-sounding vocal that SETs are known for
