A Peachtree NOVA 150 or 300 at that price range. I had the 150 for a few years. 

Fully Loaded Ragnarok?

The Nova and Ragnarok are both great suggestions.

The Schiit Yggy was my main source for years. Their gear is killer.

The Bel Canto C5i is a solid all-around performer with a small footprint.  

Many good suggestions have been offered. The PS Audio Sprout retails at $700. 

I use the Blusound Powernode with a 2nd (bedroom) system. Gives you an amp, DAC and streamer in one small box. Sounds very nice with KEF speakers.

I went with a Technics SU-G700.

We heard a system with this amp, playing MQA files, at Axpona a few years ago, and were blown away.

Paired with Martin Logan speakers, we'll see what happens!
