Dedicated circuits

Thats what I was thinking also, the 30A breaker won't kick off and that could possibly damage something and/or be a fire hazard.

Congratulations. Yeah, amazing isn’t. The stark difference doesn’t allow room for much interpretation.

I’m not sure you would classify this a significant risk. Audio equipment are fused and a dead short is a dead short and would trigger a 20a or 30a breaker. I will admit not to be a professional electrician. I assume a certified electrician did this… and would not have if it did not meet code. ?

Zero benefit, significant risk and liability and not everything is a "dead short." Even if it is, in the time to trip the breaker anything not rated for the breaker's current is a risk. 

But sure man, ignore best electrical practices for a non existent audio benefit.

I used 30 amp breakers because a few people said they give more headroom.

...another audiophile myth.

Most audiophiles don’t realize that standard (non AFCI or GFCI) circuit breakers are mainly there for short circuits, and won’t trip on in-rush current (or momentary speaker amp demands of high current). 15 amp breakers will easily intermittently pass peaks of 30 and 40 amps (and more if needed), because that’s what a typical refrigerator or air conditioner pulls when it starts up (it’s called in-rush current). A 20 amp breaker with 10 or 12 AWG wiring (14 AWG with a 15 amp breaker will be fine too), with a decent wall outlet, is all that’s needed. An isolated or dedicated ground is an added plus.

I honestly do not see any meaningful advantage with utilizing a 30 amp breaker. I can understand that psychologically (More is always better mindset) it being seen as beneficial. In terms of actual sound quality performance I can see no superiority over a 20 amp alternative.
