Bookshelf speaker rec

Hi everyone.

I am in the market for a pair of speakers, bookshelf, that have a good amount of low end. Will be using them with a Naim CD player > Conrad Johnson pre > B&K power amp.

Music is everything from Metallica and AC/DC to Beethoven and John Williams.

Room is 22x19 with a vaulted ceiling that goes from 9ft to 13 ft. I will have some carpet, and plan on putting up some acoustic panels, to, at the very least, cut down on the ambiance/reflections.

Wanted to get some suggs on what to listen to when I go to my local store(s). I would like to keep the pair under $5k if possible.

Thanks in advance.
