Hi Peter,
Thanx for the usb answer, I my simple mind with the pc technology in 2008, I thougt this was possible, but OK I can live with this

I just love the CD10, the soundquality is superb both for cd and usb playback with 16/44 WAV files. I still have some more tweaking to do, but that is just great fun to have something to work on further.
I just now tested two flac files and on WAV files, downloaded from the 2l.no site.
flac 24/96 + 24/48: Convert from FLAC -> Length error in FLAC file ....
wav 24/96: No sound and after pushing 'play' again, got the error message: ENDPOINT CREATE FAILED -> The DAC does not accept this byte sequence
