iTunes

Thanks...... I originally loaded about 650 CD's onto hard drive using default settings .. my lack of knowledge at the time. I am going to start replacing them (reloading) using Apple Lossless with error correction to rebuilt the data base in the least compromised manner before moving into Music Server land ..... . If I am saying something that does not make sense to those who know far than me (almost all of you) say so.

How important is checking that error correction box when ripping cds in iTunes? I unchecked it early on because I found that I was getting worse results, but I don't remember the details, sigh... I think it was ripping more slowly and at times giving me strange artifacts in the sound. My memory on this is vague alas.

Pretty important if you want the best rip possible.

It will take longer on dirty discs - if you have some smeared with fingerprints and peanut butter best to wash them (literally) before you rip.
