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.

I'm confused about the second (set) ground rod for the 2nd panel  issue. I'm familiar with installing two ground rods and connecting to the main panel. Sometimes a second panel (subpanel) is installed on a 2nd floor of a house for circuits in a bedroom, lights, etc... so are people suggesting we run a ground wire outside from there and connect it to a ground rod (or two)? 

A sub panel connection has different rules than a main panel.
