My understanding from post #338 is that only the tutorial was taken from the M300SE firmware. After comparing both of the firmware files, I found them to not be identical.
I haven't hooked it up to my Linux system yet, so far only Windows 10. I have heard no clicks at the start, end or between tracks of different
bitrates. I've listened to various files ranging from 44.1kHz up to DSD512 using foobar2000 with ASIO+DSD.
