@sgordoxyz Is there a reason you want to spend that kind of money? Just because you did does not mean the amps you get would actually sound better. There is something called the Veblen Effect, in which people will spend more under the illusion they are obtaining greater value, which obviously isn't the case.
High end audio is not drive by price, its driven by intention- how much (or how little) the designer wishes to present state of the art.
For example there are class D amps that are less expensive than the amps on your list that sound a lot more like music. So I would consider casting a wider net.
