[QUOTE=Mr Peabody]I know there's a big price difference between HD600's and the K-240's but the HD-600's are far more open. AKG sounds compressed in comparison. I personally feel the HD-600's are superior in overall frequency response and fidelity as well. AKG is what my HD-600's replaced. I also have a pair of 580's. I've driven the 580's with a receiver and even a tabletop HD radio with no problem. My friends I-pod seemed to do alright but my smaller mp3 players can't drive them like they can be driven.


Patrick" save yourself the headache and frustration and give the HD-600 line a try out.
to be honest" I am not the guy who like to recommend expensive AUDIO GEAR but from my experiences of trying to find THE BEST set of CAN'S FOR ME!! I have come to the conclusion that headphones are different animals"(so in short) let me say this..
my impressions are done with the HD-650 and i have to thank Mr. Peabody" for that. also I now owned a set of the HD-600 the way i got these is a real Blessing.
