Stefano, you might enjoy a read of the article I wrote about the difference between audiophile and regular versions. Specifically it discusses how and when BIAB uses the uncompressed files.

It's for Windows, but the concepts apply to Mac (I also have a Mac with the regular BIAB version). The article is a few years old, but still applicable.
