Musical Fidelity Supercharger for MBL cheapskates?

When I first read about the 550 watt superchargers, I thought it was a bad idea.

As mentioned in the Stereophile article, it's like one of the cheap car power boosters I used to use as a kid (mine had eq).

But since I have become interested in the fairly low efficiency MBL speakers, ans read about the super powerful MBL amps needed to drive them (at least the 101's) I started to think that for a cheapskate working stiff like me that can't afford the super hi watt MBL electronics but who maybe could afford an MBL speaker, that maybe the supercharger was just what the doctor ordered.

Any thoughts?

As an aside, I recently took delivery of new Atma-sphere MA1's.

Since they include a power meter, of course I had to see how many watts I was using. Turns out with my 90db efficient 4 ohm speakers I am mostly peaking at 1 watt!!! This really surprised me. (the subs are powered, however the monitors are driven full range by the MA1's) So for me (right now anyway) the 140 watts the MA1's put out (actually I read atma's typically underrate their output so they are probably over 150 watts) provides more than sufficient headroom and control. I also dont listen super loud.

I may very well end up with some MBL speakers at some point (not the 101's however - I wish) so a supercharger is probably not likely to make it into my stereo.

A supercharger, however may very well make it into my Mazda RX-8's engine bay. It really needs one and costs $1500 less than Musical Fidelity's audio "supercharger." Maybe it sounds better too.
