a no-brainer. from the first note small but significant increases in energy; more bass, more snap to transients, and better drive,pace,etc. also, slight amount of additional ambient/low-level information. took 2 minutes but one problem is i'm afraid to change the label from 2.0 to 2.2; looks like i might scratch it while doing it. if someone has done it sucessfully i would like to hear the details.
