Monster, would you say it is another level in slam from HE-400/HE-500?
HE-500 is one of my favorite headphones, period, so I think if I ever go for another flagship it would be the 6...
Theres zero comparison.I can drive both from speaker taps,so Ive measured them from the same amping....
The HE-500 was my 3rd real headphone(after HD600 and Beyer T1.1)and when I heard the 500 for the first time I was blown away by the midbass impact of the 500s,but then I got the HE-6,and its clearly on a totally different level for impact...its not even really close.
