New electrical wiring specifications

My next project is to run a new circuit to my music room.  I have 12/2 now and am going to move the receptacle to a better location and change to 10/2.  I watched a video with Michael Fremer a few years ago and he said all his equipment was on one circuit and that was recommended.  

That’s not what  Fremer has now.

I see five 120V branch circuits connected to circuit breakers installed on the same Leg, Line, in the Sub Panel. Read my comments I posted for Fremer’s sub panel.

(Note: The the wiring on the left side of the bottom of the panel. I’m not sure but I think there is a Type 2 SPD, (Surge Protection Device), mounted to the bottom of the panel.)

Appreciate the advice.  Would there be any disadvantages of having those two amp circuits sharing the ground & neutral wires by using 10/3 cable and breaking the connector tab on the receptacle?  

@jea48 I have watched so many Fremer YouTube videos, wasn't sure how old the one was where I heard him speak of 1 circuit

With your comments and intel on Fremer's latest configuration and Mike's comments, I am thinking to add at least a 2nd amp circuit when I tackle this project.

Yes. In my opinion, it will create more noise on the line. Running four dedicated branch circuits is not much more $ then running one when you factor in the cost of your amps and audio equipment. 😎

A true dedicated branch circuit does not share a neutral, hot or ground with any other branch circuits.
