I guess mine are borderline...
For now I'll just have to pretend I have a pair of good amp...
Measurements likely similar to this:
"Formally defining clipping as the 1% THD+noise figure gave maximum power delivery of
a monstrous 475W into 8 ohms (26.8dBW), way above the specified power. 850W was
available into 4 ohms (26.3dBW) and while I measured 1060W into 2 ohms (24.2 dBW)
rather than the specified 1400W, the AC line in our Santa Fe office was sagging significantly
for this measurement.

Mine is the next year model, made in 2005, I think, FPB 350 mcx - also spec'd at 350/700/1400W @ 8/4/2 Ohms
Green?
Nope.
30W (x2) standby, 100W (x2) idle, bias current step up under higher output signal, have definately seen 1kW for the pair during
enhanced listening sessions.
But they have paid for the whole system by nudging me into buying some Electric Utility shares which has produced a remarkable capital gain and continuing dividend payments.
Go figure.
