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?

The "250W" ice power module 250A is really a 150W (RMS) amplifier. Read the data sheet. Similarly, the '1000W' 1000ASP module can only sustain 85W of continuous operation at 25-degree-C, and 40W at 50-degree-C before thermal shut down occurs. Even without thermal shut down, 1000ASP can only provide 1000W for 15 seconds.

Also check out the phase shift: 250A at 20Khz is -30deg, 1000ASP is -70deg (maybe that's why they sound 'tube-like').

The H20 also works well with low capacitance IC.

Icepower does not recommend capacitive load > 470nF, or Quote Icepower data sheet: 'Higher capacitive loads may compromise stability and thus damage the device."
