Best Connection Between MAC and NAD


I have a MacBook Pro and just received a NAD C 399 with MDC2 BluOS-D module.  I'm trying to figure out what is the best way to connect them.  I started using Apple Music and coming out of the MAC headset jack into NAD audio inputs.  The quality of that audio was OK, but not great.  I attempted to use an USB-C - HDMI adapter cable into the NAD, but that did not work.

Then, I signed up for Tidal and connected a USB-C out from the MAC to a USB input for the NAD.  I believe this enabled the use of the NAD DAC.  Those helped the sound quality.  But, now I'm wondering if I should explore an optical option.  Coming out of the MAC USB-C and either using an adapter cable or dock to come out an optical connection and into the NAD optical port.

Any suggestion what would be the best configuration for connecting the MAC to the NAD?

Thanks!

Thank you so much for your great response!

I have a follow up question.  You said that you use QoBuz.  In comparing Apple Music and Tidal, it appears that Tidal has the edge on sound quality.  I'm playing the streaming into a NAD C 399 with MDC2 BluOS-D module attached to new, good stereo speakers and subwoofer.  So, sound quality is important to me.

Your choice of QoBuz over Tidal would suggest that QoBuz sound quality is better than Tidal.  My question is overall whether you think QoBuz is better than Tidal in sound quality?  Thanks!

@pacificm, Everyone has a different opinion on that question. I prefer Qobuz over Tidal but others prefer Tidal. I searched and found the following for more info:

I suggest you demo both and make your own decision. I compared Tidal vs. Qobuz for 2 weeks and selected Qobuz for its sound quality, catalog and playlists. I especially like its hi-res albums. For more info, please search on Tidal cs Qobuz for many more reports. In any case, you have to decide what sounds best, has the right catalog and ease of use for yourself.

I am streaming Qobuz using an Aurender N20 music server.
