Does anyone know what the quality of mp3s is from Amazon mp3?

What about the quality of mp3s from iTunes (the store, not ripping on pc)?

How are either of these qualities compared to buying a CD and ripping it myself with EAC and lame?

I wouldn't worry that much about possibly audible differences between 256 CBR LAME-MP3 and 256 ABR AAC per se. Rather I would worry over (I) the possibility that a "256" file is transcoded from a lossy, and (II) the chance of someone sneaking in an audible watermark, putting you at risk of purchasing an audibly inferior product regardless of file format.

There is not much we can say about exactly who makes an Amazon/iTunes file or how though. But, as much as I think the 'Mastered for iTunes' thing smells of mumbo-jumbo, the idea that iTunes specifies to the production chain 'we want precisely THIS!' appears to me as a safeguard against at least some kinds of mindlessness.

Edit: crodgers beat me at at least part of the point.
