Check the squeezecenter configuration, it should look like this for the Apple Lossless:<br /> <br /> <img src="http://imgur.com/uEkm9.jpg"><br /> <br /> Ignore lines with "alac/InguzDSP", you probably do not have them (and don't need them anyway). <br /> <br /> Apples Lossless should be converted to FLAC using ALAC/FLAC handler.<br />

If the AIFF file is losless then the FLAC created from it will be losless too.<br /> <br /> "The bit rate is high when playing an AIFF file (I created one for test purposes) but low when playing a lossless file"<br /> <br /> That part I didn't understand. AIFF IS losless file, no?<br /> <br /> It's all bits and timing, really. The data entering Touch DAC and the timing are the same in both cases (AIFF losless and FLAC).<br /> <br />

Apple lossless files are converted to FLAC or WAV before being sent to squeezebox touch so there is no loss of quality.

Did you do a blind test while comparing two different s/pdif sources with the DAC?<br /> <br /> Without blind testing, there is no objectivity.
