Fritz Carrera or other possibilities!

     I am currently shopping for monitor speakers in the $4000 price range new or used. The reviews for the Fritz Carerra's are very positive and I'm trying to explore all my options before making a decision. My room is 12x15x8. My current monitor speakers are about 4 ft. out from the wall behind them and 3 ft. from the side walls. I can be flexible with placement. This seems to work well with my current speakers.

     I don't have a lot of room treatments, but have enough soft furniture in the room that helps with absorption. I also have 2 GIK Soffit Bass traps in the corners behind the speakers, which really helped to tighten up the bass. I will be augmenting the speakers with 2 Rythmik F-12 subwoofers and I would prefer monitors, but am open to other suggestions. The room is not too overly damped or too lively, seems to be just about neutral. I sit about 10 feet from the speakers and they are about 8 feet apart in an equilateral triangle. I'm also about 2 feet from the wall behind me. I pretty much like all types of music from rock to classical to bluegrass and jazz. I'm looking for speakers that will sound good with all types of music. I like to hear warm detailed but not overly bright speakers. My limit new or used is $4000. I live in the Northeast so it's all but impossible to audition speakers in my area. Any suggestion or recommendations would be greatly appreciated!
