Hi Barry,

I think it could be the problem. MP3 import is a low quality encoding.

 • MP3 Encoder: Use if you plan to listen to music in apps other than iTunes, 
or on MP3 players other than iPod, iPhone, or iPad.

Apple iTunes default import encoding is:
 • AAC Encoder: Use for most music. You can listen to songs encoded using this 
format in iTunes, on iPhone and iPad, and on iPod models that come with a dock 
connector.

When I import original Music CDs to iTunes I use the highest quality setting: 
• AIFF Encoder: Use if you want to burn high-quality CDs with the songs you’re 
importing without losing audio quality.

Only trying to help with my advice.

Cheers,

Ronni
