The 62 is a beast! I struggled with this as well. When I upgraded it wasn't night and day. The 64 felt larger audibly and I thought it lacked in the bass dept compared to the 62. (ported vs sealed) That being said, It takes awhile to get used to it , but rest assured, it is better than the 62. . . . ever so slightly. It matches your 7's so take solace.
