Re-ripping music collection to new iMac

Tubejack: Sounds like you are using a PC. I will be using a Mac and have been advised that EAC is not available on Mac but haven't checked that out personally. I do use EAC now for ripping into the old PC (WAV) and am happy with the way it performs. I'm just hoping that the Mac salesman will be able to upload the library into the new Cavlary 2 TB HD and hence into the Mac. I presume that the library would then be in an AAIF Mac file (non-compressed). If you ripped your CDs three times, you have made some good comparisons!!

Yes, I think I can transfer the files to iTunes without a problem but I'm wondering if I would get better quality sound if I dragged out the back-up CDs themselves and "re-ripped" them using EAC. Nearly all of my music library now stored in the PC was ripped using WMP so starting over may give me better quality. The one problem, as I see it, is that my CDs are copies that I burned from other CDs using Nero Burn so perhaps the damage is already done and the "lower quality" is already inherit now in the same CD copies that I would be using to rip into the new iMac. Maybe that is an issue that even EAC or Apple cannot overcome.

Thanks for the input so far. It is sounding to me like it would be a waste of time to re-rip. The new iMac and Cavalry 2TB HD unit are both on the way so I'll follow the advice and just load it up - try out a couple of re-rips and compare. The CDs were ripped originally in a WAV format (not compressed) so there probably wouldn't be any advantage to re-ripping. You have confirmed my suspicions.
