The MDx is a new processor for all our DAC products, but it is not the network option or upgrade for the M1, that is a separate upgrade and option, regardless of the version digital processing board in the M1 as the previous revision of the digital processor in the M1 will support the network.
The MDx can accept DSD as DoP or as Native DSD data transfer, this will depend on the media player and what input is being used on the M1 on what way would be suitable.
The MDx offers improvement over earlier upgrades we offered in the M1 for clock timing and synchronization, in the past this was a parameter sync wide and fine. this improvement is one of the main benefits of the MDx. This has nothing to do with DSD, its for all inputs and clock synchronization at all sample rates.
