Dedicated line w/ upgraded parts or power cond?

Yes, thank you Jea. I did look at the code before I talked with the inspector; I will make sure I dot the 'i's'; the building will not be used as a habitable structure, but for business office/listening room. That said, I will be working with appropriate authorities to make sure it is code compliant for the area. The neighborhood I'm focused on is on the edge of downtown and consists of a mix of residential and light commercial structures. But, we are still at least several months away from buying. And, I'm also considering the possibility of either an entirely separate location for the office/system, or using the smaller Equi=Tech units that are essentially black boxes, if I am forced to go that route. Right now, I already own the big wall cabinet, though it has not been put into service, and is in storage awaiting next steps.
Again, thanks.
Best,
Bill Hart

You may find very superior results with separate units. Isolate each piece as you like, with the power they need.
And you get to keep them.

Both be a sport!!

Something I like about a dedicated line is that it is a continuous run from the panel to where you plug your gear into it.

There are no cuts and tie ins to other wall plugs, at least in the dedicated lines that I run.

I also like to attach the dedicated ground wire to the main ground wire directly instead of inside the panel to the ground strip where all the other ground wires are connected.

Would this be considered a less dirty dedicated line?

Also,I am now upgrading to 10/2 romex and 30 amp breakers,yes it's overkill,but not dangerous is it?

I ran this way once before when I had solid state amps and liked the sound, so I'm trying it again with tube amps.
