Has any had experiecne with the MF 550k superchar?

Lots of opinions from people who have not heard the superchargers. How can you say it will destroy your SET sound when you have never heard the device? I too would like to hear from someone who has experience with the superchargers.

I'd like to hear from someone who has used the supercharger as a supercharger also.

Unfortunately, nobody seems to be knocking down the door.

Well, as my old Italian landlord use to say: "whattagonnado." I was hoping, at the least, to get a reliable second hand word. I'll try the post again in a couple of months.

Warrenh--read the "Follow up" review of the 550 towards the back of the December number, written by a professional singer. Used both on its own and as a supercharger on his Aleph. Basic sonic characteristics didn't change either way, just mitigated somewhat by the Aleph. His experience echoes Elberoth 2. JA found the 750 much better, but at its price point it would make more sense to start from scratch and get a much better amp, rather than using the supercharger as a $$$ bandaid.

I thought the Aleph was SS? I'm (STILL) looking for a tuber who owns a 550. If the basics "don' change either way," isn't that what a SET guy would be looking for? Don't want to change the SET sound.
