I think we got off on the wrong foot here. I apologize for my part in that. To clarify, my beef is with your purporting something to be fact when it's an educated guess, suspicion, or anything but fact. In some of your posts, you can across like you were stating fact when it was actually your suspicion and opinion. It's certainly fine to have, hold, and share an opinion or suspicion as long as it's clearly identified as such.
I shared your suspicion before my Asgard arrived. I purposely let the amp fully saturate with heat and let it run a few more hours beyond that and checked (subjectively) the output. It was not obviously diminished. The amp still had plenty of reserve on hand to play continuously far louder that I could stand to listen. I went so far as to take the headphones off, set them on the bench and crank the volume to max, both when the amp was cool and when it was hot. I did not instrument or measure anything except by my ears so it was all subjective, but I don't seem to see the problem you suspect is there.
So I guess we both have opinions, one based on subjective experience, one based on suspicion alone.
BTW, the "Professional" SPL Auditor and Phonitor amps list their specs the same way. Does that make them dishonest too?
Also BTW, it's not about what I own or not, it's about what I've experienced. I generally don't write about gear I've never seen, particularly in a way that might be construed in any way other then speculative.
