Questioning a/c isolation for digital.?

That sounds like ample power supply. I also went with 10 guage wire. I found larger than necessary transformers are a benefit. I think "relaxing" of the music by the additional power transformer is an appropriate adjective. I think cleaner sound has a more relaxed musical feel. Do your transformers have a duplex outlet receptacle?

My transformers are fed straight from the main breaker box on 30 amp breakers. The transformers then feed the isolated copper outlets in my music room walls directly using 10 gauge Romex wire.

Sounds effective and robust.

It is the best sound I have had from my system. I think I now have “round” cymbals. The isolation transformers clean up the sound so well.

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.
