Hey: I'll chime in on the powercord issue. Marigo Ultra 4 cords in "K" or "T" tuning types. Tonally, fundamentally, musically, the best I've heard-and they really piss-me-off cause they should not whomp the Shunyata King Cobras V2's I use (but they do!). Anyone, and I mean anyone whom is auditioning super-HI-end power cords should audition these in their system.
