Another impressive combination was this - when it worked that is ...
The first time I heard the HE-6 but when you listen at volume to shut out background noise from the hall, you move your head slightly and the signal on one channel gets lost and comes back after an inch of a turn in the other direction it's pretty irritating. Obvious cable plug issues on the headphones. They should have had their act together for this kind of combination.
That point off my chest , the sound was pretty close to SR-009 territory in my book. Completely effortless but also lacking soundstage behind the HD800's.
I apologize for the channel dropout issue, the cable was accidentally yanked. We had a backup but it hadn't been burnt in fully and sounded bright.
