Hi Bobbo,
Welcome to Apple Discussions
The problem is with the conversion bit rate used when loading the CD into iTunes.
Convert
iTunes gives you the ability to convert music files from one file format to another. You can also convert a file to the same format, but use different options. For example, you can convert some high-bitrate MP3 files to a lower bitrate to fit more of them on an MP3 CD. Note that music purchased from the iTunes Music Store can't be converted.
Search iTunes help for Convert to find instructions on how to change the bit rate to a lower setting.
Full instructions from Apple here
iTunes: About the Add to Library, Import, and Convert functions
Regards
Colin R.
