Came upon this thread by search. I'm in Fresno, CA and would love to hear some headphones, especially the HD650. Not sure if the Guitar Center here carries them, but I'm scared of wearing out my welcome there since they've already opened the Shure 840, AT M50x, V-MODA M100, and a couple lower range Sennheisers for me in the past. Still not having found the headphone I'm looking for, I feel I must go up in price and quality. And unfortunately, Guitar Center doesn't carry the NAD HP50, Philips X2, and some others I'm considering.
