Outwith Itunes purchases I download my music from CDs onto itunes. I clean the CDs first. I use Apple Lossless Encoder with the error correction box checked. But some still end up jumping/skipping. My most recent purchase was David Bowie's 'All Saints', and the beautiful 'Some Are' from the Philip Glass Low Symphony becomes unlistenable at points. Any suggestions please, avoiding jargon and complex programmes, I'm a bit simple!
