I would suggest the Sony MDR-CD3000s. An old favorite, not mentioned as much around here yet still worthy of serious consideration.
If that is true and that audiovideosale.net company really has the Sony CD3000 for $460, I am buying a pair next month, without question, no excuses, writing it in stone this moment. I don't care if my rent is late, those will be mine. I owned the CD1000 and they were some of the best full-size I had ever heard at the time (surpassed by the 3000 of course, not by leaps or bounds though, but enough of a difference to purchase the 3000 over the 1000 now).
And if AudioCubes really has OEM replacement drivers for the CD3000, that is even better.
Edit: So don't anyone take my pair of CD3000 away from me please. They also have the CD2000 for $204, which was released a year or two later, and might be better than the CD1000 but not the CD3000.
