I think we may be mixing apples and oranges here, The Oppo can play multichannel PCM files from my NAS. But if you want the best sound quality you are feeding the rear USB input with DSD 512 material (straight or upsampled/converted). That can only be done in 2-channel and would require a significantly more expensive chip implementation to provide that same quality in 5.1 channels. As much as I’d love to see that implemented in a 305 versiuon, it will likely need to be at a meaningfully higher price point.
Kal: are you aware of a multichannel implementation that gets you Oppo equivalent 2-channel DSD 512 playback sound quality in a 5.1 channel configuration at anywhere near the price?
Nope, there is no multichannel solution above the miniDSP UDAC-8 but below the exaSound e38 except HDMI into a prepro or AVR. FWIW, I cannot play DSD512 but see no need for it. I play my files in native format and I have only 1 DSD512 recording.
Just a quick question. If you use a Mac as server is it possible to send DSD258 and DSD512 to the Oppo 205 - it looks like no driver is needed for Mac and I just worried that there were limits to what level of DSD that could be send by MAC over USB to the Oppo
Yes. Do I only look at the Stereo Signal sub menu set it down-mix, or also at “speaker configuration” submenu, and change those to stereo down mix, speakers to large, no subwoofer, as well?
How about crossovers? I don’t one any crossovers applied on Oppo, since I have the preamp taking care of those
If you only connect it with two speakers and without subwoofer, then yes, you should set both to large, no subwoofer, and downmix to stereo. Crossover setting should not matter if all speakers are set to large.
This depends whether you listen to multichannel music or stereo music only. If you only listen to stereo music, you needn’t to down mix the signal via oppo (you can use the setting of rrwwss52). If your source is multichannel music, you have two possibilities: use the down mix of the Oppo and send the stereo signal to your amp or let your amp doing the down mix. I do it the second way.
It appears that once the dedicated stereo outs on Oppo are connected to a stereo pre or integrated or amp, then nothing on the other settings (such as Audio Processing) matter.
