Thanks for the professional input ... I love how I can get advice on darn near anything on this forum in addition to the MB advice.

I was in concert choir in high school, but that's the extent of my classically trained ear. I have an appreciation of classical music and very good hearing but that's about where it ends. I do feel like I hear a difference between the m4as I have in the car now and what I had originally done with the album, rip it to AAC off the CD. Is that just my imagination? I really only notice it on three tracks, which are a symphony. The m4as vary from 745 kpbs to 1081 kpbs. Yes, this is my glovebox Nano ... but it's actually a new one, with 16 Gigs instead of the inadequate 2. I only have 2.7 filled so far so I'm not space-conscious ... yet.
