Main vs. sub panel for dedicated lines


I am building a second home on my property. Will have a dedicated audio room. I will be routing 2 or 3 dedicated lines for my audio system. The high current devices for the home will be run off the main panel. I will install a sub panel supplied by the main to accommodate power for 2 bedrooms and a 1/2 bathroom.  

Question, should I run my dedicated lines off the main or the sub panel? I could move some of the high current devices to the sub panel if needed.

Thanks in advance for advice.

Sure, I'll check for you. 
Are the two rods connected together by a bare #6 solid copper wire?
I don't recall seeing them connected. Can each rod individually be connected to ground in the main panel?

Sure. Especially for your situation. Both rods ground wires would connect to the service entrance neutral conductor neutral bar.

I would also recommend grounding the ground to ground, and then grounding the Earth to ground. You never can be too sure, so I would ground all the grounds to all the pipes as well. Because, like, they go into the ground. 

Yeah, I know what you're thinking. There he goes being a a-hole again. But no, this actually is code now. The difference between all this BS everyone is so intent on doing, and what actually works, is so obvious if you could hear it that would be the end of that. But you can't. It is way too much work. You never in your life will do it to compare and know. That's why I did it. To know. Then comes the reason I hardly ever bother posting on the subject, https://youtu.be/9FnO3igOkOk?t=39

MC, finally a post of yours that makes sense. :)

Broken down into simple English.
To earth ground a sub panel or not to earth ground a sub panel that is the question......
