That's good to hear, I like what the 2's did, happy that the 3's are just more of the same. You're right, the 3's don't come cheap! I did well selling the 2's though so that will help. Are you using an aftermarket cable at all?
Only on my Senn HD 580 (the Senn HD 650 cable) and the HD 600 (a true after market cable upgrade).
