you might want to try the new pro900's. they are not quite in the same league as the ED9's, but they have a very similar sound. good detail. a bit more bass than ED9's. And you can get them online for about $330.
I dug the 900's so much I returned them and bought the ED9's.
I love the ED9's and no regrets, but honestly I could have lived just fine with the 900's.
Also think about B&H photo in NYC. You can order online and have 30 days to return. I tried many ultrasones...
