Sonnet Audio Morpheus

What are users impression of DoP.  DSD over PCM.
I understand thisd does not play DSD "natively"

@ducatirider - The Sonnet Audio Morpheus (and the Metrum DACs) only decode PCM, no DSD support at all. In order to play DSD files you would need to convert them to PCM either before playback or on the fly.

DSD over PCM (DoP) is not PCM, but is the DSD data encoded into PCM frames for transmission. In order to support DoP playback a DAC must be DSD compatible, but instead of converting native DSD it first recognizes the PCM frames as being DoP and then converts the data back to the original DSD to then be converted to analog. So PCM only DACs do not support DoP playback.

When DoP data is decoded back into DSD by a DAC which supports it, the recovered datastream should be identical to the original DSD. Therefore if there's a difference in the sound quality of DoP compared to the original DSD it's not due to a difference in the data, but could be cuased from additional processing required to decode the DoP back to DSD and potential noise that the conversion might create.

Thanks Bill
