Turns Out, Mastered for iTunes May Be Nothing New

Posted by tom.dennehy on March 20, 2012 at 06:31:22:
I downloaded the Master for iTunes tools and procesed my test set of 24-96 WAV masters. In all cases, the afconvert program in the MfI toolkit produced an AAC file virtually identical to the one produced by standard iTunes. They were not exactly identical, but the audible difference amounted to occasional burps and murmurs. You have to conclude that the tools temselves are nothing new.

So it seems MfI is a concept, a carrot for the industry to create unique masters optimized for compression using existing tools, because there wasn't the incentive before. But, does certification a priori imply improvement?
