Regardless of genre, source, or a file's resolution, what I heard from my headphones was the epitome of "audiophile sound quality." Yes, that description has become a bit of a cliché ever since "audiophile sound quality" has been appropriated by the mass-market audio industry. But I'd be wasting the reader's time going through each recording and attempting to elaborate on what I heard, such as its slamming, deep bass, transparent midrange, and sparkling treble. This is because the recording determined the FiiO M17's sound quality and which headphones I was using much more than the sound quality provided by the M17. In other words, FiiO's M17 sounds exceptionally transparent. I can think of no greater praise for an audio component.
