After three days listening, I couldn't be happier with the HD600. It performs exactly as I would wish it to.
Makes my best recordings sound spectacular – pristine, detailed and airy.
Plays nicely and forgivingly with my many older, rougher recordings.
Has all the zip I need when listening to plucked-string acoustic music, like my collection of lute recordings.
No part of the sound seems to be artificially emphasized.
It's like having a relaxing yet invigorating bath and having the water constantly at the right temperature, never too hot or too cold, but just right.
