New H20 Signature S250


After reaading a lot of reviews about these amps, i emailed Henry to build me (2) S250 to biamp my speakers, I have an immediate response from him and this is what he say:

Hi Patrick,

The Amps are the Signature Stereo which has an addional Big Toroidal
transfomrer which makes it a true dual mono design, for $300 more which
makes the amp now $2800. Of course, The amp is improved over the
regular stereo across the whole Audio Spectrum. If you want the regular
version stereo, let me know.

Thanks for the number and I'll try to give you a call sometime today.

Henry

Does anyone yet owned this amp?

Hi all,

I just finished a very satisfying audition of the H20 Signature Stereo. It is a wonderful sounding amp and Henry is a true gentleman to deal with! I could easily live with this amp and may yet, but... there is at least one more amp that I would like to audition. The Butler 2250 has me very intrigued and I was wondering if anyone has had any experiences with that amp. I realize that it is a completely different animal and that it sucks up a lot more household power (from the specs) than the ultra efficient ICE power amps. I do environmental work and I live in California, so reducing my energy bills does matter... up to a point. Thanks.
How long have you had the H2O? After break in, there are system changes you can look at to bring the very best out the H2O. I have heard the Butler, but never the two in the same room. The Butler is a fine amp. I'm in California too. The H2O is a green machine, and so is my theater projector.
According to Harry, the unit was fully broken in. I only had for it for about 5 days which was long enough for me to get a good feel for the sound. And a very fine sound it was! There was some transformer hum though that Harry attributed to either loose transformers from all the shipping and/or DC from my power line. I was wondering if the PS Audio "Humbuster" would cure that problem?
Any thoughts on leaving the S250 powered on continuously or power down after each listening session?
