Denafrips Ares DAC has arrived... need help with Oppo connectivity


Gents,
I got the Denafrips DAC today and connected it to my Oppo 103 via coax and USB and get no signal.  I suspect there is some programming necessary to connect to the DAC.   Can anyone guide me through the Oppo programming necessary.  I don't know how to get to the Menu set up screen since I used my Oppo exclusively for audio.  Any help will be appreciated.

Stforth,
I had Don Sachs upgrade all my Harman Kardon Citation gear (I, II, and V), but his preamp is vastly better than the upgraded C-I.  Don is a genius with both his tube preamp, based on 6SN7 tubes, and his KT88-based amp.  In my experience, his tube gear gives one a glimpse of high-end sound at a fraction of the cost of major audio companies.   Send me a PM and I will be happy to chat with you about the preamp.  

I have fooled around with a boatload of modestly-priced cables, but really like the Cerious Technology graphene cables, followed by Silnote and Shunyata.   I could hear more difference in SQ swapping the various IC's and power cords than I have with the 4 DACs I have auditioned.  Cheers, Mark

@stfoth  
the Ares was the most "different" sounding from the others I've recently tried/owned. Not necessarily better or worse, but different.

Can you elaborate? How so? Thanks.
@whitestix   Perhaps try another source and then conduct the evaluation???

From the components you list in your system, I don't see the Oppo 103 at the same level. In my opinion, it appears to be an odd choice, again-- my opinion -- (BTW, I am a fan of Oppo) -- I mean, why leave Don Sachs' genius unrealized???

Agree with david_ten, try another source. Perhaps the Oppo blocks the external dac from use somehow (says the guy with no real knowledge of how this stuff works). Or the use of USB creates a problem (ditto).
