As for your disdain for Class A SS amps and running hot:
They have the same longevity (and sometimes longer!) when compared to other non-Class A SS amps. I've got some Class A amps (all Nelson Pass designs) from the 80s and 90s that I still use several hours for a few days almost every week. They are still running strong. Of course, after about 15+ years of ownership, I had the supply caps replaced (as you would have to do with any amp) but that is it. They've been rock solid. I don't think running hot has anything to do with longevity in modern Class A amps.
Now, if you don't like them because they are not eco-friendly, that I can understand. But the sound is oh so good.
In any case, have fun listening to them all - including the Mac.
