I don't use the radio. There may have been an improvement there along with bringing in RDS.
Let me provide some additional info.
I have both a Clip+ and ClipZip and I made comparative subjective listening tests at same vol, sound settings etc for both flac audio files and the FM radio, using my old Sony MDR CD10 headset. I made an a/b switch setup, so I could quickly switch the headset between the two players, while playing the same flac files on each player or with the FM radio tuned to the same station.
To my ears the results were:
1. Flac files - No discernible difference between Clip+ or ClipZip could be heard. Clearly the audio amp characteristics are the same.
2. FM radio - ClipZip has a fuller sound than the Clip+ at the lower end of the freq spectrum. This is not due to the audio amp, but suggests the CZ tuner provides a wider freq response than the Clip+ tuner.
