I have a pass labs xa25. I cannot compare it to the amp you are considering. I have not heard it. Though the xa25 does not get too hot at all.
It shines in midrange, it’s warm, very quiet, and forgiving with poorly mastered cds. I can only advise regarding the xa25 that you do not utilize oversized spades on the amp side. They only partially fit. Also a speaker cable of silver and copper 50/50 reveals more detail. All copper and it might sound a bit flat. I’m running them with special 40s in a very small living room. Works well for me.
Best luck!
