How should I connect my Oppo 83 (Wolfsen Dac) to my Onkyo 876 AVR (Burr-Brown Dac, 2 HDMI outputs) for the very best 2 channel analog sound quality from my CD collection? Thanks very much for helping a beginner.

Thank you.

Your 876 does not have direct channel inputs. I'd use the HDMI audio from the Oppo. IIRC using the analog outs will just cause the digital signal to be decoded in the Oppo and coded to digital once it reaches the Onkyo then back to analog and injected into the amp section. Seems counter-intuitive to do it this way but thats how Onkyo does it.

Give it a try and see which gives you better audio. My experience with several AV processors that had no direct analog path seemed to yield no differences. My current AV Processor is an Integra DHC 40.1 - very similar to your 876. I find no difference using analog or optical/coax out from my Oppo BDP-80 vs using the HDMI path.

When all else fails - RTFM!

Thank you Knucklehead90 for that info. As a beginner I must say I don't quite understand your AV language therefore don't understand how to connect the cables as you are suggesting.

For example, what does "does not have direct channel inputs" mean? What does IIRC mean? You say "see which gives you better audio" but I don't see in your reply where you explain 2 different ways to connect the 2 components. For a begginer like me I hate to say it but please give the names of the input and outputs on the back of each component when you say how to connect, that is the only way I know how to follow your explanation. I hate to be so dumb regarding this subject but I am trying to learn. Thank you for your understanding.

Thank you.

You can
  • use an HDMI cable (digital audio)
  • use a pair of old-fashioned, RCA cables (analog audio)
Then, if one sounds better than the other, it "gives you better audio."
I wouldn't expect much difference, but it's you who needs to be satisfied.

Got it, I understand it now. Left and Right RCA's on Oppo to Left and Right "CD" input on Onkyo, right? Or, HDMI.

Thank you.

Yep, correct. Is the Oppo only being used for CD playback or will you be spinning Blurays occasionally?

Used for BR's also, why do you ask. I do have it connected via HDMI for BR's and L&R connection to CD input for CD's if that's what you were going to say. Thanks.

Thank you.

Just curious. I have a single HDMI running from my 83 into my AVR.

Gotcha. I listen to CD's about 60% on my system and 40% movies eventhough I have a 10' wide screen and projector.

Thank you.

Good for you-I wish I listened to that much music, and I've got a pretty good collection. Since both sets of your cables are run, I would imagine you could switch back and forth fairly easily with the same disc to see which connection you prefer. I'm guessing they would be fairly indistinguishable provided the levels are matched.

You're right, I can't tell one from the other really except that analog seems to be a little less harsh and a little more musical. Of course when you switch them back and forth for testing the digital is much louder and has to be turned down but after turning it down the differences are very subtle as described above, at least to my ears.

Thank you.
