Just as a follow up, I was listening to a Tech Guy radio show and heard mention of DVD Audio Extractor. Downloaded the fully functional 30 Day Trial and wallah!, great sounding CD.
EDIT: Wow, great sounding CD!...but, according to the SONOS app on my iPad, the Apple Lossless ALAC files are apparently too large to send over my mediocre 100mb wi-fi network to my SONOS Speakers. I assume I need to convert the ALAC files to something smaller. My worry is that a smaller file won’t sound as good as the Lossless one, true? What file should I convert them to?
Also, the SONOS message displayed is ‘network connection insufficient to maintain playback buffer’.
