$2000 speaker help

I posted under the amp section and everyone agreed that I should choose speakers first.

I'm considering the B&W cm8, Paradigm Studio 60, Dali Ikon 6 Mk2, Salk Songtower QWT, and Ascend Acoustics Sierra tower.

I listen to mostly rock, jazz and electronic. Smaller room 15X20. I'll be upgrading the amp next, so I'm not sure my current amp needs to be considered. Not interested in using an additional sub.
