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?

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?
Leave it on. The H2O, at rest, consumes about as much as your refrigerator light.
I'd consider leaving it on, power draw not an issue but the chance of damage from surges, spikes and the like has me concerned.
