1) What changes with every new FLAC release (and every new lossless format release)? Is it possible that files encoded with an older FLAC encoder are worse in any kind of way than files encoded with the latest encoder?
2) Is there any serious difference other than "preference" between FLAC, ALAC and WMA Lossless?
3) Is there any difference between Apple's ALAC and dbPowerAMP ALAC? Should I prefer a specific one for iPod and iTunes use? Does dbPowerAMP uses the same encoder with iTunes 9?
Thanks a lot for your time and your answers!
