It would help if you also mentioned your sonic priorities and feature sets you need.
All amplifiers in this range are likely to be good. Given that you have stand mount speakers (I assume I have the correct), you probably don’t listen at super high volumes - or are you also using a sub? And, if so, are you driving that sub from the speaker taps and rolling it off, or are you rolling off your 805s?
I think the integrates you mention are all well-respected. Side note - I personally wouldn’t buy D’Agostino because I understand he supports far right political narratives. That is me - I don’t expect others to agree but mention it in case it’s important to you as well.
Others that you might consider would be Vitus, Constellation, Gryphon and what I purchased: T+A PA 3100HV. It’s a bit above your price range but it’s possible you’d find a dealer who get close to your budget. Personally, I think it’s spectacular - but I am also biased by what I own. Bias or not, it’s worth a look. (They also have models in their R series that would come in a bit below your stated budget that are also quite good.)
