I would HIGHLY suggest towers from Bowers & Wilkins. The 684 floorstandings are incredible. I demo-ed these w/ a friend and we were both very impressed. The clarity and purity is pristine. Listening at high volumes does not hurt your ears as there is virtually no distortion(even on a mid-range receiver). Simply put, the sound these towers deliver is the exact sound the band/performer wants you to hear. They run for about $1,100 for the pair. Sadly, I do not own these but hope to one day purchase some B&W's.
As far as receivers, I like Yamaha's such as the RX V663.
