Well, if you want the best audio experience you can get, you're going to need an Amp/DAC to go along with the headphones, which can be pricey. Anyway, the rig I'd recommend you would be the Sennheiser HD800 ($1,500~) and the Woo Audio WA2 ($1,200). I'd recommend reading up on Head-Fi threads on both of them. Good luck.
