First of all, thank you for your job.
I had Klaus's mod but did not achieve to get the USB work properly...
Thanks to you it is Ok now.
My Dac is the Audio GD NFB 1WM. I did not make serious tests but I
think the USB input outpasses the SPDIF one.
For Windows users, I suggest to use WinScp to edit / create the files.
(copy / paste is possible)
