Neutral pics. Spendy.
GR07 Neutral with a slight lower highs bump that almost disappears with burn in..Fantastic detail and clarity. A neutral standard.
EX600 Neutral smooth a bit laid back sounding, does nothing wrong but bass fans will want more bass.
CKM77s Balanced more detail than the other 2 a bit on the brighter side but detail for a dynamic is 2nd to none. Jazz/rock on these has to be heard. Just astounding. My pic out of the 3...Absolute neutral I would go for the EX600..The GR07 has better bass so more musical imo. Then the CKM77s has better detail than anything else I have and the bass is perfect. No bloat just perfect for every type of music.
