ran through a series of experiments last night and ended up where i was:
when comparing putting my transport on 60/60 power (via 3kva signal DU tranny) vs adding a separate 1kva tranny downstream of the 60/60, preferred the latter.
when comparing the 1kva downstream of 60/60 vs 120/0, 60/60 preferred.
preferences largely defined in quick ABA testing to determine lowest noise floor / microdetail retrieval / treble tonality / dynamics.
oh, and the transport ground is floated (all others have ground)
point being: so long as the transformer is big enough, more is better when it comes to motors in your rig. --kind of like how your rig sounds better when the fridge /washerdryer /AC is on vs off.
the addition of isolation transformers will greatly help digital gear (best digital i ever heard was esoteric P/D02, and it had 4 transformers per chassis! i'm simply adding them outside, with good results), but make sure sizing is adequate...analog stage requires power more than digital circuitry.
and power cords always seem to help.
