WOW, so glad I posted this! Love the responses so far - EXACTLY what I'm looking for! GREAT looking stuff!

Thanks, guys for taking the time to post. I'll be looking at these pieces more in depth later on today.

This Bel Canto Stream 2 might fit the bill and is only $1995 new.  Here’s an excerpt from a Twittering Machines review…

Just for fun, I substituted the more costly review Prima Luna EVO 300 Hybrid Tube Integrated Amplifier (more info) for the C6i to see how well the e.One Stream2 plays with others. Cuing up the digital version of Careful answered that question—swimmingly! The Prima Luna is lush, rich, and powerful and this system—Bel Canto e.One Stream/Prima Luna EVO 300 /DeVore O/96—delivered even more impactful yet delicate and detailed sound. Sometimes more is more. As a streaming DAC, the Bel Canto e.One Stream2 tells a very convincing story, and in this system it offered a smooth, punchy and rich sound. For its asking price of $1995, I think it represents great value and great performance through its analog outputs. If you’re on the hunt for a streaming DAC, I recommend adding the e.One Stream2 to your short list.

Look at the Sonore rendu streamers from Small Green Computer. 

Chord Hugo2 and its paired streamer 2go will do all you are asking for. Not much bigger than a wallet. Having an excellent headphone amp built in, Chords DAC are sublime. Also is portable.
