I just came across this DAC and it seems to implement a couple of the features I keep asking for
http://www.lessloss.com/ - Master clock output, so you don't need the asynchronous resampler
 - Multi-stage dejitter curcuit with independent local clock
 - measurements look okay 
Might benefit from a Bryston class A analog stage but seems to have a contemporary digital section and some geeky features like driving the DACs and opamps via rechargable batteries. 
Cheers
