Stream Qobuz on Oppo BDP105

-USB Audio: up to 2ch/192kHz PCM, 2ch DSD 2.8224MHz/5.6448MHz
-Coaxial/Optical Audio: Dolby Digital, DTS, AAC, up to 2ch/96kHz PCM
-LAN/ethernet

I would obviously like to stream highest quality Qobuz.

I wouldn't get too hung up on all the high-res stuff.  How it was recorded and mastered matters a lot more than the bit rate. 

The DAC in the Oppo is decent, but it's probably not going to resolve the finest details and a lot depends on the rest of your system. 

The higher bit-rate recordings may sound a little different, but not necessarily better.  I've heard a lot of FLAC level recordings on Qobuz that sounded fantastic and some hi-res offerings that were lackluster.

I stream it through my Oppo from my phone using the Opp's front HDMI port. Sounds fantastic.

@simao......So a "Lightning-to-HDMI" adapter with Qobuz app on my iPhone will work? Would a "Lightning-to-USB" adapter work connected to the front USB 2.0 input connector? Would one be better quality with audio?

Pretty sure the HDMI would be the better option but if you already have the USB cable ( very likely) give it a try.
Hope your phone is on your home wifi to help stream the hires stuff!
