Not sure why all the guesswork - the manual is online.
The NS1 will accept MQA content via ethernet and USB stick input but:
When playing MQA through the NS1 coupled with MQA-enabled DAC, the NS1 will output MQA Core decoded signal. The MQA-enabled DAC will display the original sample rate of the MQA stream. In case of the DV2 DAC, the Optilink input currently cannot fully render MQA streams beyond the Core decoding of 24bit, 96kHz.
