optical from pc

[johnnyturbo]

hi all-

is there an inherent weakness in using optical out from my pc to cac? alternatively, is the usb/firewire out inherently preferabke?

 

thaniks for you advice.

 

happy holidays to all.

Some says Toslink has very high jitter, so you need a DAC that can manhandle it. Firewire is probably preferable in theory, USB depends on the implementation (async etc.). But a bad Firewire DAC can be worse than a good DAC on optical so... Life is not simple.

thanks for your response. it 'seems' that the 'quality' is in the implementation: in the case of optical out, a solid jitter rejecting dac is essential.

"in the case of optical out, a solid jitter rejecting dac is essential"

But if you have that, Toslink may beat coaxial. It does in my setup, using the Sq.box to feed the DAC.
