My first thought was how about the Konus Audio Essence speakers (single Jordan driver in a transmission line cabinet) driven by a 47 Labs Gaincard and either level of the digital combos.
The Essence speakers are low in profile, available with various beatiful wood finishes, and designed to be placed close to back walls.
I believe this system would fit the rest of your criteria as well, in terms of the sound produced.
There are also various off-shoots of these products that can be had for less, but your budget could afford an all new 47 Labs system, let alone buying a piece here or there used. The off-shoot brands include Carolina Audio JTM speakers, Audio Zone amps and dacs, and Scott Nixon amps and dacs. I would tend to look at the 47 Labs stuff first, IMO however.
