RP-600M

Wharfedale all the way . I own the Klipsch RP 600m II and I hated them. Absolutely hated the boosted highs and scooped out mids. No warmth or details. Just screechy highs. I bought the Lintons and I’ve never been happier.

I would choose different speakers. (Besides your Crutchfield links don’t work. Don’t try to escape the underscores.) EAC review of Klipsch RP-600M Spending less on the amplifier (go with e.g. Yamaha A-S301) and slightly over budget with better speakers. E.g. ELAC Debut 3.0 DB63-BK (EAC review).

That is a large living room. Unfortunately the Klipsch speakers are rear ported, and I have mine on approximately 60 cm tall Target stands. I have an open plan main floor, my audio listening rig is at the top of the L in an L shaped floor plan where the long side of the L is approximately 14.7m long
