newbie making first amp choice

I recently purchased New Advent Loudspeakers (large) in great condition and a used Music Hall 25.2 CD player. The Advents can run a little brassy especially with CD's so I've been thinking of warming the sound up with a tube or hybrid amp. I rarely crank it really loud, quality normal volume listening is more important. I listen to rock, jazz, blues, and decent country. My budget for the amp is 400-700 which means I'm starting to look at things like Fatman, or Chinese brands like Quinpu. I'm also quite open to going with a Music Hall, Cambridge, NAD, solid state if that's better. Interested in any opinions. Right now using old Kenwood KA-305 (40 wpc/1980's I think).
