Hi Chris - I wrote this a few months ago on the HD600 thread when I was posed a similar question. It still mirrors my thoughts today. Funny thing was that one of the Admins here obviously thought it was worth highlighting, and it actually made the front page for a while. Anyway - here's the post .....
I'm embarrassed to say that I've already read this review, and I had forgotten that you had written it!
A nice review BTW.
It only increases my HD600 lust.
