Pass labs xa25 amp and BW 804 d3?

I had B&W Nautilus 804s for years, and have heard most of the B&W lineup over time. I can tell you, without reservation, that B&Ws are power hungry and, IMHO, need at least 150 wpc to even begin showing what they can do. Personally, I paired them with a 225 wpc power amp and they sounded good.
