Query: Great Headphone.......

This is my first serious headphones. After 10 hours break in they started to rock!!!!! I never liked to listen to music in my mobile( Google G1). But with SE 530, music from my mobile sounds fantastic. PRAT is very good.I already have MF V-Can headphone AMP. The both sound great together!!!!
