Hi! An avid iPod/apple user here. It's only a few months since I converted my entire cd collection to AAC@224. However with headphone upgrades etc., I now realize that AAC@224 doesn't any longer do the trick for me. Still doing everything all over again in AAC@320 would be a gigantic effort, so I was just wondering if anyone knows if there is a new version (improvement of the) of the AAC-format planned in relatively near future? I read something about AAC+, but didn't get a clear idea about what it stood for. It would be kind of a drag to do the whole thing again in 320kbit, only to realize a couple of months later that some new and better format was available. Of course, I could encode everything in the Apple lossless format, but would a wave-lossless-aac route give less soundquality in the AAC-file (because of the extra link in the convertion chain)? Any tips or help would be greatly appreciated. Thanks!
