Seems like you made a subjective judgment - at best similar performance - about the Atmasphere amp without having heard it. Nothing objective about that.
I said:
"I would not pay $5000 for an amp that offers me at best similar performance to one priced at $1000- it’s a non-starter."
What makes you think this is a subjective statement? I have been asking for measurements consistently and have said ad nauseam there is no value in discussing, debating, or arguing, subjective opinions about amp performance. Clearly if you had read and understood my comments you would have realized I am referring to objective performance above. Since the manufacturer has refused to produce the measurements, we can not compare the performance, thus my "at best" qualifier.
However, neither Ralph or any other designer has to be beholden to the design approaches that you favor. And, if they feel that their differently designed amps warrant a different price point that is their choice; they understand the market and their business objectives. No one is forcing anyone to buy anything. If you get musical satisfaction with Class D at the $1000 price point, great; if someone else gets Class D musical satisfaction at $3000, $5000 or whatever, great. There’s no right or wrong in that.
I don't believe I have said anything that contradicts the above, which is all obvious on its face. I have stated that the amp, from an objective performance standpoint, provided that at best it performs as well as the current state of the art, is a poor value at 4x the price. That's MY opinion, based on fact. As you astutely remarked, "There’s no right or wrong in that."
