Pass labs INT-250 just 500 bucks short of you budget
From my experience with pass with my gen 1 uno’s from Avant-garde acoustics is that the bigger you go up in there gear (pass amps or integrated amp) you get more body to every sound and wonderful bass extension with the large amount of head room
Currently using the XA 160.8 mono blocks can’t be more pleased with that kinda power gone thru horns
