Of the speakers on your list I've owned only the Vandersteens. They were way too large for the room I had at the time so they never got a fair evaluation. That being said, I'm going to recommend you check out the Polk Audio LSi-15. These speakers are extremely well reviewed and fit within your budget. I find them to be very revealing but never hard to listen to.
Okay, so they aren't esoteric. They are worth investigating.
