Hi! I have some issues with the Meridian Explorer 2 DAC. Firstly, the DAC info in Audirvana says that the Explorer supports DSD64. This is not correct. Secondly, when trying to play a DSD64 file, I only hear a hiss. DSD128 play fine, though. I have the latest version of Audirvana on a MacBook Pro Big Sur using USB-C connection to the DAC. / Jan Gustafsson
Hello @jan_gustafsson,
Can you send me a copy of the “Debug Info”? You can get it in Audirvana Settings>General>Debug Info
Note: By clicking on the Debug Info button, Audirvana automatically copies all its content, all you have to do is paste it in response to this message
That’s detection error. The Explorer2 does not support DSD at all. The reason why you can play DSD128 is because it’s automatically converted to PCM.
In the Native DSD streaming method, just select “none: convert to PCM”. You need to stop the playback (by clicking on the square STOP button) to be able to change that.
