550 Watt pro Kanal bei 0,5 Ohm ----> 23.45V pk/0.5R ----> 46.90A pk
500 Watt pro Kanal bei 1 Ohm ----> 31.62V pk/1R ----> 31.62A pk
400 Watt pro Kanal bei 2 Ohm ----> 40V pk/2R ----> 20A pk

It likely use a 2 x 45V power supply along with 12 pairs of output power
transistors per channel.

Given the low supply voltage the output transistors can logicaly withstand significantly
higher currents without entailing their SOA than would be the case with amplifiers
supplying the same power output in higher impedance loads , so the high current
figures are not that impressive.

Who have heard this amp particularly suited for low impedance loudspeakers ?
Are there a simplified schematic (functional diagram) ?
Unfortunately I don't find informations and test reports in english.
