My advice is to look into BESL, Revel, Salk, JBL Synthesis, Linkwitz, Status Acoustics, Martin Logan, Gedlee, Seaton Sound, Phase Tech DARTS, Snell, Perfect 8, Ohm Walsh, Magnepan, Apogee, Quad, Nola by Accent, PMC, Spendor, Harbeth, ATC, Genelec, Focal Pro, NHT XDs, Legend Acoustics, and Acoustic Zen.
and then finally decide DIY some DEQX active 3 ways cuz it's cheaper!
seriously though, Infinity, Salk, JTR, Magnepan, PSB, Def Tech, EMP, Aperion, SVS and Ascend do all make nice and affordable speakers worth your time.
