For $1,500 this is the way I'd go:
Speakers: Elac Uni-Fi UB5 (currently on sale for $350 @ Amazon, normally $500/pair, and they'll easily best speakers costing quite a bit more)
Amp: Elac Element EA101EQ (currently on sale for $620 @ Amazon)
Subwoofer: Either SVS SB12-NSD ($449) or Rythmik L12 ($539)
You didn't explicitly mention a subwoofer, but if you're going with bookshelves, and want to do things headphones can't do, one of the big things being tactile response from the music, you want a sub. The beauty of the Elac Element integrated is that it has built in subwoofer integration with automatic room EQ and subwoofer blend including phase adjustment, so you can get the speakers and sub working beautifully together. It also has a built-in USB DAC so it's easy to hook up to your computer.
I have the UB5, SB12-NSD, Elac Element comb. I use it for my computer audio setup and it's excellent. The Rythmik sub is certainly worth a look though. Either way you're within spitting distance of your budget.
