I'm thinking about upgrading my Ultrasone Dj1 pro's and i cant get my mind off of the alessandro MS-2i's. I know there would be a difference between the headphones, but would the difference between the headphones justify the difference in price? I listen mostly to rock, some jazz, some rap, and some alternative. And would buying a littledot mk2 amp make the alessandro's significantly better or would my denon receiver be fine?
