I don't see anything stated in either document or even any implication that it maintains pure Class A operation into the lower impedances. The higher power output shown in orange is additional headroom available beyond the rated power before clipping, but I don't see anything stated there relating it to the Class A or AB power bias points.

This is common in what are referred to as Pure Class A bias (fixed bias) amps since the output devices and heat sinks cannot dissipate the amp's full rated power into lower impedances. I don't intend to get into a long winded dispute on the topic, so I'll respectfully bow out of the discussion at this point. For the record I love the sound of Accuphase gear having owned one of their Class A amps in the past and have nothing but respect for their design quality and sonic performance.
Your alternative 'facts'.
It does not matter how you interpret the specs (imagination).
The only thing that matters is what the Accuphase engineers have done (facts).
And that's exactly what I described in my post #25 above.
And if you do not want to believe me, ask Accuphase directly; they will tell you the same.

Hello, I have to make a hard decision, between P-7300 and A-75.
Actually I have P-7100.
Another option is to revert back to E-800.

How do you compare:
1. P-7300 vs A-75?
2. E-800 vs C-2450 + P7100?

Thanks
