... is it danceable?
... is it danceable?
Or, if it would cost dramatically more, would it wrong to simply include one of those into the design of the DAC and just put it straight inside the case, hardwired to the rest of the DAC?

What a Novel idea!
Using your ears to decide if something sounds good rather than reading posts, measurements, and specs.
Nah, thats just too strange....it will never catch on...

using toslink? I also did some real world experiments: my Firestone Bravo S/PDIF transporter uses a WM8804 chip to reclock S/PDIF to 50ps. When feeding my Firestone Spitfire DAC, a 15cm homebrew 75Ω tinned copped coax cable sounded noticeably tighter and clearer than this 65 strands glass toslink 6ft cable. Both were running off linear regulated PSU's and the Bravo is using a Tenor chip, which I filter w/ an ADUM4160 dongle.
Toslink requires 2 light conversions...m2tech said that toslink was unmanageable jitter-wise when releasing their hiface, it's in their FAQ. Very often you can see 700/800ps jitter mesurements for toslink, but even the best S/PDIF receivers(such as DIR9001) only provide a 50ps clock recovery.
Toslink. I would rather not get into a jittter debate here. All I can say is that with my system and rapid switching *I* could not hear differences between the two inputs
Not so long ago I used to wake up in the middle of the night in sweat after having nightmare about my PC not outputting bit-perfect and jitter corrupting signal down my optical cable.
To the OP: why don't YOU just listen to both and decide for YOURSELF what sound YOU like most.
Spending too much time on Head-fi feels like being in the Matrix. You need to decide NOW if you want to take the red pill or the blue pill?
I've got no problem believing that you would not hear a difference between a plastic toslink cable through a CS8416 S/PDIF receiver and a PCM2704 USB input. Especially when the Zero is using OPA2604 opamps(if you didn't swap them).
Jitter is the plague of digital audio, and the reason(together w/ the galvanic isolation) why ppl prefer coax over USB or toslink....now the OP can buy the best gear he can afford, and hear it for himself

Did you compare a low jitter short coax against that crummy PCM2704 USB controller? I'm sure you could source an Hiface from a seller w/ a return policy. I don't know how good this would sound, but definitely better than plastic toslink or PCM2704. This PDF about WM8804 discusses the audio jitter audibility, and was presented at an AES convention: http://www.wolfsonmicro.com/documents/uploads/misc/en/A_high_performance_SPDIF_receiver_Oct_2006.pdf
Whatever you think about my DAC's USB receiver it won't make jitter any more audible.
[1] So I take it that you have never tried a low jitter coax transport...because its improvement will be inaudible anyway, right? So all the ppl raving about a clearer and more focused sound in the Hiface thread are defenseless victims of teh evil placebo?
[2]You ran a shootout of audio cables, maybe trying a low jitter coax transport could shed some lights too...It's highly unlikely that, using some transparent-enough headphones, you wouldn't hear a diff. between the Hiface and the USB/toslink inputs of your Zero DAC. Just saying
