Advantage using one electrical leg for audio system?

Is the advantage for a using the same leg important for noise or something else?

I have two dedicated circuits feeding system now which share a bipolar breaker Ie 20 amp + 20 amp. Ie. Each 20 amp breaker is on a different leg.

NO.. Two 10/2 with ground Romex cables fed from single pole breakers fed from the same Line, Leg,... IS Much, Much, better than what you have now... .

Actually I am presently running my gear on three runs of 12-2 fed from single pole breakers fed from the same Line, Leg. I am still intending to get some type of strip that I feel I can live with to experiment with running off of only one circuit.

Is it a noise issue? It's unfortunate that they are not on the same leg, but is the problem here a noise issue?
