You can't hurt the audio no matter what setting you use, that's how lossless compression works. There is no reason to use less than the maximum compression level when ripping a CD. The maximum compression just means that more tries are made to make the compressed file as small as possible. No matter how compressed the stored data is, it will always be lossless and sound exactly like it does before compression. It's also always the same amount of processing power to decode no matter which setting you use and there are never compatibility issues. I personally believe the option should be removed from ripping software because it only serves to confuse people.
