Manual says FLAC is supported, has anyone tried?
Converting to FLAC files will reproduce the source information without degradation. It will not, however, make anything sound better. Converting a poor recording to FLAC does nothing for the quality of the recording. If you purchase HD music though, it is appropriate to save it as a lossless file (FLAC or otherwise) to preserve the integrity of the recording.Yes, no problem for CD rips converted to FLAC. I haven't tried higher bitrates yet.
Probably not. If you have a high quality recording, the quality of the music is limited by the weakest link .In this case it would apparently be the HK system.Does it make much difference if a lossless compression method is used in car audio considering the quality of the HK system and road noise, etc. ?
