Rog designed them, so I would say he rather likes them .

3800/4 = 950W per driver (in theory), @ 4 drivers per channel (2ohm stereo)

Also, some drivers are not quite 8ohms, so resulting load seen by amplifier will be less than 2ohms, incurring excessive current draw and amp heat build up.

I think Rog said Amp is approx 85% efficient, so in certain situations

Max current draw(7600W/0.85)/240V = approx 38 amps, So you are gonna need hefty, hefty power source to get anywhere near the full capability of this amp @ 2ohm stereo.

When I said hefty power source, I meant 240V@32amps.

does he? i thought he ran all 8 off one?

sometimes he plays with 3 stacks (like at the last U.O.D) but I'm pretty sure it's one stack per amp channel what ever the ocasion
