I haven't seen ANY official spec that calls it class A up to 30 W. We know Luxman rated the amp's total output to 30W, but reviewers have found it puts out significantly more.
Luxman is cagey in it's description as well, referring to bringing the "Class A sound" but I have yet to see it officially listed as a Class A amplifier.
What is interesting is the idle and max power: 260 and 380. That's pretty close to what I'd expect for a full class A amp.
My own theory is that the 30 to 90 W difference may have more to do with the tortuous standards related to power ratings. Last I recall a manufacturer must pre-heat the amp for an hour at 1/3rd power, and THEN test it. This may have required far too large a heat sink/chasis, but this is me second guessing the manufacturer with little to go on.
Best,
E
