Hi-
Thanks for the ideas. I am glad to know about Pasternack. (Current cable is Black Cat Cable--BNC on one end with RCA adapter on the end that connects to Bifrost DAC.)
I checked coax settings etc on Bifrost. That doesn't seem to be it.
I got this reply from Hegel.
"Thank you for your email. Please note that there are no settings required for using the digital output. However, connecting the digital and analog outputs simultaneously to different systems could in some cases lead to grounding issues that disturbs the digital signal.
In this setup I would recommend connecting your Viking CD player directly to your headphone amp with analog cables as this would give you way better sound quality than using an external DAC. Viking is designed to be used with analog connections, you will not get any sound quality benefits from the special technology used with the digital output. "
Hmmm. I am sort of interested in an upgrade, so now I am wondering about moving the Bifrost/Lyr 2 elsewhere and getting a Schitt Moljnir 3. Then I could run balanced cables directly to the headphone amp, while the RCA's are connected to the Brinkmann amp that drives my speakers. I hadn't really considered bypassing an external dac on the headphone setup, but this seems pretty simple?
Thoughts?
cheers and thanks,
Margot
