My Oppo 203 is connected to network using ethernet. It is also connected to Nucleus using HDMI. I use HDMI out of the Oppo to Bose. If you want to use the Oppo DAC, you have to use RCA out of the Oppo.
I think I can play multichannel using the HDMI connections, but I’m not 100 percent certain.
MCH = Multichannel? If so I’ve got some SACD .ISO files that I have converted to 5.1 DSF files. I play them directly through the oppo using their crappy interface, no Roon. If not multichannel and you mean a file with .mch extension, no I don’t have any.
I use the DAC on the Oppo-203 and 5.1 analogue out to Sunfire Theater Grand IV. Truth be told I’m not much of a fan of multi channel music. Neat once in a while but more of gimmick, IMHO. I do love me some 7.1 channel movies though on the same Oppo/Sunfire system.
I have played some “multi-channel” files from Tidal and they play out of all 5 speakers using HDMI connections, but I’m not 100 percent sure if it’s playing multi-channel or what. I’m not a huge fan of it either. Music should be stereo IMHO.
I have a NUC/Rock via HDMI to OPPO 205 with 7.1 analog and HDMI to a Denon 8500H. It does play MCH, receiver display is showing multi-channel input.
With HDMI to the OPPO you have the option of the OPPO doing the decoding with the 7.1 analog outputs to the preamp or the preamp will do the decoding over HDMI. If you don’t plan to use the OPPO 7.1 analog out then use NUC HDMI to preamp. It will play mch over HDMI either way.
Why? I don’t need to know. I use Roon to stream from Tidal and Qobuz. I didn’t purchase my Oppo 203 or Bose system for Roon. I already had them. I’m just interested in playing and listening to music. I did purchase a Nucleus for Roon, because I didn’t like running Roon on my laptop.
If you want to point me at such a disc, I might order it. I don’t know that it would be a correct test playing from the Oppo 203 to Bose without using Tidal, Qobuz, Roon, or the Nucleus. I guess a file could be saved to my Roon database, but then I would need a CD player other than the Oppo to burn the file.
Thanks Kal for the test file. It played each of 5 discrete channels. It did not play on my subwoofer. This is using the Nucleus > HDMI > Oppo 203 > HDMI > Dolby Atmos TV > HDMI > Bose 5.1 connection. I did not try using the ethernet > Oppo 203 connection, but will later.
Yes, there is silence when playing to my Bose subwoofer. It works when playing music from Roon, so not an issue for me. My TV is an LG65C7P OLED. It is Dolby Atmos capable, so I’m sure it’s passing whatever it receives from the Oppo 203. My Bose is a Dolby Digital 5.1 surround sound system, not Dolby Atmos.
None of this really matters to me. However, you asked me to stop guessing and with your help I did. I think we confirmed that when using HDMI, the Nucleus can pass 5 discrete channels to the Oppo 203 and the Oppo 203 can pass 5 discrete channels using HDMI to a sound system.
I still prefer music in stereo and normally listen using the ethernet connection. That also gives me a visual image on my TV screen which I don’t get when using the HDMI connection.
