Thank you for the useful feedback. The only one of those CDs I have is Nora Jones "Come Away With Me" and if I can find it, I'll report my polarity findings for my example. And I did forget to mention that my 2 and 8GM ipod nano's invert uncompressed 16 bit 44.1KHz music files.
I'd like to know which CD player, speakers, crossover slopes or headphones you listened to the CDs with. And you didn't state which polarity Dylan's voice is in.
