Hey i'm looking to spend up to $1000 on a headphone setup. Currently I have an Chaintech AV-710 flashed to Audiotrak Prodigy 7.1 which runs to my surround sound setup (Kenwood receiver, Wharfedale Xarus towers, Wharfedale SW-150 sub, etc). Now I want something I can listen to at night in my room. Open headphones are fine. I will be using the PC with the Chaintech AV-710 for the headphone setup. I also have a Cowon D2 mp3 player I would like to use from time to time. So I guess I need: Headphones Amp Maybe DAC? I cant spend over $1000 on all this combined. Thanks!
