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.

You guys didn't get the point this is a marketing scam! You are trading transparency for power.

Putting one amplifier in series with another is not a great idea, hence even Carver stopped with it.

If you want the control of solid state with the musicality of tubes then you buy a tube preamp and mate it with a solid state amp.

There was another company marketing a distortion box which would make a solid state amp sound like a tube amp, this is no different.

I have heard the supercharger and it sounds like a good solid state amp period, however, if I was going to pursue Musical Fidelity I would buy a separate amplifier from them and not a super charger.

The supercharger increases the power of any 50 watt plus amplifier to over 550 watts rms so typical can't be used with low powered SETs.

Athipaul, like any amp that is added in series, the ultimate output is a function of the output of the 'last' amplifier in the series. So, as long as the SET amp has enough voltage to drive the following amp, low powered SETs can be used. Even 1/10th of a watt should be able to drive the Supercharger.
Still, what a strange way to get more power!?

Athipaul also came up with the info i found before.MF claims that.But Inpepi is right.In Stereophile they connected Supercharger with 18 W/ch tube amp.It worked just fine.

But has any SET owner out there tried this and can he make some comments on the sound changes?

As I mentioned in another post, I think one of the few systems that could perhaps benefit from this is MBL 101's. They can use alot of power to wake up supposedly.
