Nothing has been cancelled. We are just thinking out loud.

OK, sorry. I misread that.
The thing is: I would like to implement a USB I2S source with the Buffalo DAC.

A search yesterday showed that apparently you can run the buffalo from the clock of another asyncronous-device.
You can connect the external clock to the buffalo, disable the XO-regulator and your done. (Is it that easy?)

I guess this also works when you have other SPDIF sources instead of the I2S source connected.

How would this compare to other solutions with seperated clocks or an additional teleporter line?
I am not sure if I can squeeze a USB-board with PS into my DAC box, so I originally planed to use a teleporter line to another box. In terms of performance and sound quality, would it be worth the "squeezing" and use a good external clock next to the buffalo? So that you have only one master clock that gets the USB data via asyncronous interface?

I always figured, that the buffalo is alright with its own good clock and consequently seperate clocks can be used.
Has someone compared the two solutions or are there measerable advantages for the one or other solution?

And finally: how would a teleporter-line influence the signal?
My knowledge is, that every part in a digital signal-line adds its own jitter (or do you say phase noise now) and the teleporter is maybe no exception.
Is there some experience out there if an added teleporter line will be inferior to a side by side solution?

I think that a really good powersupply is a must for a USB interface and also for the teleporter-modules.

Thank you.
