I have a new Squeezebox Touch that I am feeding into a Levinson 390S, using the coaxial input to access the DAC. The Touch sounds good playing internet radio, streaming with iTunes and WAV files off a USB drive.
However, I have not been able to play any 24/96 files from a USB drive [the front panel on the 390S shows no input]. I have tried 24/96 WAV and FLAC files.
I burned a 24/96 file WAV file onto a CD and played it on the 390S- it sounded terible- very thin and small soundstage.
The specs for the Levinson DAC claim 24/352 processing. I can't find any info about what file formats it can handle. Could this problem be related to the issue that Atkinson uncovered in the Jan 2004 review- the dac downsampled to 16 bit?
