I currently own Grado SR-325i's, but would like to try some other 'phones. Looking for stores that carry other decent brands, and hopefully some headphone amps.

I don't know of anywhere around here to find that, however, there are some folks planning a Head-Fi meet in the area in July which would provide a great chance to hear some good stuff.  http://www.head-fi.org/forums/f24/colorado-front-range-summer-meet-7-26-08-a-299499/

I used to own SR-225's and enjoyed them a lot.  I've also had Senn HD-600's, Audio Technica ATH-A900's, and some others. 

My current large phones are Beyer DT-880's, which I really like.  I'd like to try the AKG K701's sometime.

Well, at the least, I'd like to know which stores carry headphones other than Grado.
