I find 007 (current MK2 version, with port mod) more transparent and fast than 009.
009 exagerates small level details and has an artificial treble. My amp is neutral, with grain free treble and mids (KGSSHV Mini) and my DAC is not bright (PS Nuwave DSD via Singxer SU-1, i2s). My 007 sounds neutral and natural with my chain, but 009 not. Also, 007 spots better the source changes. Swapping PS Audio Nuwave for a worse DAC (Focusrite Scarlett 2i2 or Audient ID22) made it sound bright and thin, not natural and real like with the Nuwave DSD. 009 sounded thin and bright with the two DACs.
If that's not the definition of transparency and speed...
Don't want to dismiss anyone's opinion, but if one of the most reputed mastering engineers on the world says: "009 wasn't even a contender, you have to be deaf to prefer it over port modded 007", using his own mastered tracks and educated, critical ear, with tons of experience with reference grade audio transducers...you can't differ with him, sorry, he is not your regular clueless reviewer paid by a magazine.
Brighter doesn't mean more transparent.
