I have seen large amplifiers before but never seen one this large that was class AB. This is Boulder class size with their own branded capacitors and such. And while not as stuffed as a Boulder class A amp, it was still massive.

I like the way they translate the watts into Horse Power in their spec! Pretty appropriate I think.

Glad to see the caps were rated to 105 degC, but if I did the math rightly then 888 W into 8 ohms means about +/-120 V min rail voltage (really probably >+/-125 V) so those 100 V caps must be in series-parallel... Machining to 1 mil is pretty impressive.

Notice the chromed transformer covers

They may have missed a marketing angle:

"Chromium is remarkable for its magnetic properties: it is the only elemental solid which shows antiferromagnetic ordering at room temperature (and below). Above 38 °C, it changes to paramagnetic."

Even if that doesn't mean anything it sounds good.

Glad to see the caps were rated to 105 degC, but if I did the math rightly then 888 W into 8 ohms means about +/-120 V

Does it have differential output? Seems to.

"Power Output Capable of Over 746W RMS (1 Horsepower) @ 1kHz x 2 Fully Differential Channels @ 8 Ohms"

Then 60V rails would do, wouldn't they? When the + is driven to +60, the negative is -60 (not ground), giving the 120V across the load.

That could be (i.e. effectively bridged output amps) -- I did not read that. The symmetric modules and such and fact that it is mono seems an indicator... Your turn to correct my mis-thoughts; too many other things going on right now (far removed from audio stuff).

Usually you're so "right" and "complete" it's difficult to add anything of consequence.

I wouldn't have caught it except my own amps are differential and I had to think about the consequences of that sometime in the past.
