how to use Aurliac Altair G1 - no lightning DS App anymore

OP, Yes sir, just plug your digital output from your new device into the Auralic, go to the DAC menu and switch the input to whichever connection you are using (i.e., USB, Optical, Coax, etc.)

Then turn off all the unused functions such as Processor, Streamer, Library etc.

Great - thank you for the advice. that sounds like the best solution for me right now (and does not involve me dropping another $3k for a new streamer/DAC)

While many users praise Roon for its interface and library management, a subset of audiophiles has reported complaints regarding its sound quality (SQ), often describing it as "hard-edged," "flat," "colored," or "anemic" compared to native streaming apps or direct-from-server playback.  Anyway not my business. Enjoy the music. 

@lanx0003 no worries - I appreciate the input.

I never thought that you could hear a difference between 2 different hi-res digital sources that were being processed through the same DAC and Preamp/Amp combo.

But I did in fact notice (think I posted about this a while ago) how I could hear a significant difference between playing the same song via Qobuz versus a ripped lossless file (with the ripped lossless file sounding better)

At this point, for $599 for a Nucleus One, and the ability to keep using the Auralic DACs, I am willing to give it a try.

Thank you
