I hear the same going from the iPhone 4 to the iPhone 5. The iPhone 5 lacks depth, width, and air by comparison. Upper bass and mids are more forward, and the treble is unrefined. Less transparent, less emotional, and more digital overall. Apple Lossless on the iPhone 5 sounds worse than LAME -V0 on the iPhone 4. This is a disappointment considering how great the new iPad sounds.
