Another Luxman 590AXII owner. It's actually high bias Class A to 30 watts, then A/B to 100. The 30 watts is enough for most everything. That said, it's really heavy, at 65 lbs. Never gets hot to my knowledge. It sounds like Class D is really advancing with makers like Atmasphere innovating. When the consensus is the sound and value exceeds Class A and the products are light weight, run cool, are priced right and are better for the planet to boot, count me in.
Ditching Class A Amps due to Heat - Sort of a Poll
A discussion elsewhere about the future of Class A made me wonder how true one statement really is. So the questions are...
Have you done away with your Class A Amp due to Heat concerns?
Will you be moving away from Class A Amp due to Heat concerns?
Will you never buy a Class A Amp due to Heat concerns?
I only have a class A/B unit that does Class A up to 6 watts with almost no heat so really can't speak for those who have used in the past or currently own and run Class A Amps.
