Hands down beats the Bluesound and under $1k.
Topping D70 Pro Sabre, has to be Pro which is basically the MKII. I have one here at work, a Topping G5, a Mytek Brooklyn; and a T+A DAC 200 at home, as well as a iFi Pro iDSD (MkI, not signature) and this D70 Pro holds its own, very impressive at the price point. Can be used in Preamp mode, missing a headphone amp.
Not many on this side of the fence care to research. But reading up on Audio Science review you can hear and learn comments from the guys (and gals) who design and build these things...past the pretty boxes.
