Quad panel outlet - can I do one circuit on this?

I’m trying to evaluate the benefit of having 2 20 amp circuit breakers feeding into a double outlet positioned behind a quad outlet plate (ie, a multi branch circuit) vs. Modifying it to a double outlet being fed by 1 20 amp circuit breaker. Do I lose that much by making this change in terms of reduced noise benefit?

In light of the multi branch circuit not really being 2 dedicated circuits, does it matter very much if I power of those double outlets with one 20 amp circuit breaker versus a double pole configuration (ie. 40 AMps total).

I don’t really need 40 Amps of power and while 2 dedicated circuits would be highly preferable I’m not sure existing multi branch configuration I have is achieving anywhere near what 2 dedicated circuits would achieve. So why not free up panel availability by just having one circuit breaker Power the double outlets. I still have 10 gauge wire feeding it so the benefits of that are still there.

Then I could take the leftover 20 amp circuit breaker and wire to another location in the house which also has a listening room and create a new dedicated Circuit into this room.

So no digital stuff mixing in it appears. And certainly not a TV set. So it's somewhat pure.

I'm a little confused on this point. You had all your gear on one dedicated line versus having it spread around to 3 dedicated lines.

I understand not much of a difference which may speak to nature of the gear and your system and overall electricity quality.

But I think most might prefer the three dedicated line approach if you can do it. 

It's not about availability of power to meet all the needs of the audio gear, which is generally not very much.

I had 2 600 W mono blocks, a 5 channel amplifier, tv, AV processor, preamp, Power conditioner, a few lights, modem, router, weather station and a couple network switches all living off of a 15 amp circuit with lots of room to spare I believe. Sounds good.  Then I added 2 dedicated circuits with 10 gauge wire for all the audio gear and it has been noticeable in a very favorable way.

It's about the clarity and isolation of the electricity and making sure less restricted Power availability is always there which is enhanced with a higher gauge electrical wire.

If you had your choice between using 2 20 amp circuit breakers to power a Multi branch outlet configuration involving 2 duplexes, and a single 20 amp circuit breaker to power those same 2 duplexes, is there any benefit in having a second 20 amp circuit breaker involved? This assumes you don't need the additional power.

Because a multi branch configuration is not really 2 dedicated circuits, why not just use one dedicated Circuit breaker to power the two duplexes.  I am planning to remove one of the 20 amp circuit breakers and eliminate the multi branch configuration because I see no value in thie Second circuit breaker being used. Best to use it for a truly dedicated circuit elsewhere.
