Opinions on Possible New Set Up

Well, I have a bad case of upgrade-itis. I’ve been thinking that since my room is pretty small (9x10x8), is well treated, and I listen at low volume anyway, that I may not need such big speakers (B&W N804s) and powerful amp (MF A300cr - 225 wpc). Thinking of going for a pair of Stirling Broadcast LS3/5A V2 and a Pass Labs XA25. Preamp is a BAT VK-3i. Any thoughts on this possible new set up?
