Please don't forget that these are CDs. They are NOT the best format for audio available. Yes, the most popular and widely available, but there literally is a better format called Blu-ray Disc. If you have a Bose system, check out some concert BDs or just movies with very good soundtracks (The Dark Knight). If you use my Dark Knight experiment, then go buy the soundtrack on CD. I haven't done this personally, but I would bet a lot that the BD sound will knock you out.
OK, it's really just a rant, but I'm not a big believer in lossless formats for music. The only way to do it is what you're trying with CD to computer, which as I said isn't all that great IMO. I'll take the slight audio hit for all the space I save. Even when I have used Apple TV to listen to audio on a Dolby sound system with Bose speakers, I can't tell that I'm missing anything.
If Apple would start selling music in the DTS Audio format that I bought a couple of albums on, then we might start talking about lossless files. Until then, AAC is pretty darn good.
