That was it! OSX Audio Midi needs to be set at 24/176.4 LOL! How was I to know that the MinimServer stream was transcoded to 24/176.4?? hahaha

BTW why did you pick that?

And perhaps you need to put that info on the website....

Or is it buried somewhere there already LOL!

Hey Simon. This DSD transcoding is pretty cool Smile

Cheers

RE: DoPWave problems
What's interesting is an encoded multichannel DSD file actually streams to the Oppo as well. And plays. Sure with the same problem, so the encoding doesn't work and I'd doubt the Oppo supports Dop... but the file plays all the same with the same "faint music" in the background.... So could this be a way around their UPnP DSD issue? Playing the file via the Oppo's GUI using UPnP didn't even "mount" the file..remember that issue?

No, it's buried in the DoP specification. See this page.

For this to work on Mac OS X, the OPPO would need to support DoP. This is because Mac OS X is only able to play PCM to a USB DAC. Encoding the DSD signal within PCM using DoP is a way to fool the Mac into thinking it's playing a PCM file, but the DAC knows the real truth.

On other platforms such as Windows or Linux, it might be possible to send native DSD to the OPPO via a USB connection without the need for DoP encoding. You would need to find out whether the OPPO can accept a DSD stream via USB. I haven't done any investigation into this.

^The Oppo doesn't do any more than 24/192 PCM via USB. Go figure.....
