haha yes i was looking at the m2tech hiface, evo, off ramp and audio gd digital interface to get coax output from my macbook pro but have since put that thought on hold.
I have tried running a monoprice and van den hul optical from my macbook pro with default 44.1khz and 16/24bit midi audio setting. Then, i ran the stock usb cable that Jan gave. The usb cable sounded fuller at the expense of clarity. I have heard others claiming that Digital Interface from Audio-GD did make an audible improvement for their setup. I am kinda sitting on the fence now.
Only bad thing about USB is that it will produce some weird noise when I power up my macbook pro. I guess it is due to the fact that my mac is releasing some electronic signal to all its usb port to detect what is connected to it but sadly that signal has been processed and turned into a noise.
As of now, I am feeding 44.1khz/16bit of data into StageDAC and letting the DAC does the 8-fold upsampling. =)

The Stagedac, which uses the W8804 receiver, seems to do a remarkable job with jitter. My iPod Touch +Onkyo NDS1 dock ( with jitter specs of just 10ps) sound identical to the coax out of my STX (measured at 1.48ns by Stereophile). Make you wonders about all the jitter malarky on this forum!....
