Yeah, I'm aware of that statement on their web site, but irrespective of their advert, I actually experienced at least half of that for myself so I thought it would be good to share that. I'm not sure about the AKG bit since we can't hear the Valhalla yet, but...
Interestingly, the HD600 has a nominal impedance of 300 ohms or so. The AKG's are more like 62 ohms and have a much less reactive impedance profile. Go figure....



























The more correct version would be ..."They sounded as good as I ever remembered them sounding."
