They have six 100 watt digital amps.100W according to the marketing dept. The spec on the Panasonic website says:
100W per channel (10Hz-20kHz, 6 ohms, 0.9% THD).
I've never seen a distortion rating that high. And everyone else rates amps at 8 ohms. A proper rating would also state how many channels are being driven. I doubt it NAD would rate the same amp above 50W.
