It's a lot to ask for but nuforce claims amazing performance from the HDP.
And if the DAC section is as good as their CDP-8 for 44.1_16, and beat things 10x the price...this thing could really be a winner. Of course we'll have to see.
One thing that maybe you could answer now as it probably won't change. In your testing, did you feel there was any quality difference between using usb, toslink, or coaxial digital?

I have not finished evaluating it, but the 24/96 USB is probably up to the quality of the optical at 24/96 from Macbook, from the limited testing I have done so far. And it does a great job with 16/44.1 files too.
They finalized and overnighted the production version to me today (2/9), but it was late enough that I don't know if I'll have it Wednesday or Thursday. I'll send back the burned-in prototype overnight to be modded to final version, and that will be sent back to me for the review. In the meantime I will be testing out the production model as soon as it arrives, with them expecting to be ready to ship around Friday.

Just be careful and don't assume the HDP also uses an ESS SABRE DAC like the uDAC.
NOW FOR NEW PHOTOS!
Front - volume knob top, selector for
USB,
Digital, or
Analog.
USB selects the 24/96 USB input.
Digital will select the RCA coax as default unless a 3.5mm optical cable is plugged in then that over-rides the RCA coax.
Analog will select the RCA input as default unless a 3.5mm analog connector is plugged in, then it will use that. These were choices made in order to keep costs down. I am using the USB for Macbook, Coax for Marantz CD5001, and an iMod Vcap dock into the RCA analog inputs.
