Excellent review, as always, FK. I really enjoyed reading about your swapping of cables and their profound effect(s) on the music.
It really amazes me at all of the details buried in recordings. Thank goodness there are products that helps us audiophiles get 'closer to the music'!

In FK's review he states that he doesn't like the idea of consumers being able to "pick their flavor ". But isn't that what you're doing by swapping out cables, picking what colorations you want and don't want? I'm scratching my head.
