So, I'm curious about what the m192 mkII is doing with regard to upsampling, so I wrote to them asking what happens now that the mkII no longer has the upsampling button of its predecessor. Here's their (very prompt) response:
"the new M192MK2 have a fixed upsampling at 192kHz/24bit.
This allows a more straight digital signal path and we can optimize the analog section only for this sampling frequency.
This design is like our flagship DAC, Extremo"
What does that mean?
