Thank you guys for your advices, i think i'm gonna order the Denon. I'll post my small review as soon as possible !

Hello everyone ! I am pretty new in this forum but I have been reading a lot of reviews here for a long time (that's why I bought my cowon Z2 !!) I currently  have a cowon Z2 (terrific sound by the way !) with JVC HA S600. These headphones are moderately good for an everyday use with you...
