Floorstanding Speakers for Bluesy Rock 5-10k ?

I currently have a sweet little apartment system (Naim/Harbeth/Michell). This system has been wonderfully versatile in the sense that it's compact, highly musical, excellent at low volumes, and provides a very natural and organic presentation. My only gripe is the dynamic range and bass response, but you can only expect so much from a mini-monitor with a 5" driver. I can't change the laws of physics.

I hope to purchase my first home in the near future, and with it, a proper full-range hifi system. This time, I want to get floorstanding speakers that can really bring ALL of my music to life.

I listen to two genres EXCLUSIVELY:

1. Bluesy Rock (Black Keys, White Stripes, Dead Weather, Spoon, Hendrix, etc.)

2. Indie/Folk/Acoustic (Feist, Cash, Conor O'berst, M. Ward, Ben Harper, Sufjan Stevens, etc.)

My current system handles the Indie/Folk/Acoustic music beautifully, but lacks the dynamic range and bass oomph to really bring that bluesy rock sound to life. I'm looking for floorstanding speakers in the $5-10k range that will excel at BOTH of these genres. I still want the immediacy, delicacy and clarity for tracks with solo vocals, but I also need something that's capable of handling that big, fat, crunchy blues sound. In other words, I need floorstanding speakers that can make these 3 albums sound as best as they possibly can:
- Black Keys: Chulahoma
- Feist: The Reminder
- Bright Eyes: I'm Wide Awake it's Morning

To save on costs, I would use my existing electronics and simply move the Harbeth P3ESRs to a different room with a small inexpensive integrated amp. That means the floorstanding speakers would be paired with Naim gear (Nait 5i or XS range) and the Michell TechnoDec. I wouldn't mind UK speakers, if only to keep the British theme alive.

So, what are the likely candidates given my criteria? Any help would be greatly appreciated!
