in order of importance:
1) LIFT GROUND. (why they don't have a ground switch is beyond me)
2) replace the corcom filtered IEC with an Oyaide or ATL (i don't like furutech much, but even they'd be an improvement). the existing one is soldered on, for mechanical integrity
3) synergistic black fuse. (this is also the most expensive of the 3)
between the 3, it made mid-afternoon listening better than 1am before the changes. DO IT.
