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!

Agreed on the analog outs. Plus, if you use the Oppo, you'll have to use Oppo's bass management which likely isn't as extensive at your BK.

I'd stick with the BK. Unless you own the SE Oppo, it's unlikely the Oppo's DACs are superior to your Ref 70's.
