I set the output from DOP format to NONE
looks like the problem is finally solved
based on topping document its written to choose DSD bitstream in DOP format
what that means to set it to NONE ?
As per my previous post, you did the right thing. So now PCM will be sent to your DAC "natively" as PCM and not be converted to DSD.
But you probably also want to send DSD as DSD, so your DAC can decode the native DSD signal. As it is set up now, MC is converting DSD to PCM before sending it to your DAC. Let's set it to keep DSD as DSD:
Tools > Options > Audio > Settings > Bitstreaming > DSD
That should tell MC to send your DSD files unchanged to your DAC. I believe the Mac version of MC always uses DSD over DoP, so that should work correctly.
Note that this is bitstreaming, which means that nothing gets changed for these DSD files. So no DSP is applied, no EQ, etc. If you want to use those features with DSD files, it won't work with bitstreaming. Most people very concerned about DSD don't want to use DSP anyway. I'm just mentioning it in case you care.
Good luck,
Brian.
