Need suggestions for new speakers under $5K

Hey everyone,

I'm thinking about building a second system in my living room. The room is much bigger than my tiny bedroom (please look at my system) and I'm very open to advices. It's about 12' x 18' with a large opening to the dining room.

The speakers will be hooked up to McIntosh MC7300 power amp (300Wpc) and the MCD7008 CD player. I've decided to use my C40 pre amp as an integrated amp for my bedroom, which I found out works really well.

I mostly listen to classical music and a lot of jazz at very loud levels, but also listen to every other genre including metal, rap, pop, but excluding country (no offense). I'm not looking for the most "accurate" pair of speakers, but a pair that's very "enjoyable" and "musical". It needs to be really full range, at least giving me a clean, loud 30Hz drum thwack. I don't plan on adding a subwoofer to the system. My budget is $5K new or used, but would prefer to spend less if possible.

I'd appreciate any recommendations and suggestions,

Thanks,

Seong
