I just read the review.
A couple of parts made me laugh.
"big, information-rich high-resolution audio file"
"A switch to a more prosaic 16-bit/44.1kHz file"
So.. a hi res file has more information than a 'cd quality' file, does it! (In the human audible range.)
Well, I do recall reading a what hi fi artical on digital audio that was, shall we say, less than technically correct.
