Oppo 83

I don't know much about these multi channel receivers, but isn't Toslink a digital interface? If that's the case, you would not be taking advantage of the Oppo's internal DAC, as you'd just take the Oppo's digital signal and use the B&K's DAC. Or so it seems to me, anyway--maybe someone with more knowledge of the B&K can provide a better answer.

As far as I know,you would use the analog outs of the Oppo,
to use the Oppo's Dac.
Or that's at least how I use my cdp's dacs is the analog outs.

Yep gotta use ANALOG outs to make use of a players digital to ANALOG converter!
