how did the snowstorm end up treating you?
Remember that the electrical code is for life safety and does not guarantee hum/buzz free installations.
Would think since the console is in the same room go direct eliminating extra connectors and reduce loop area.
Console-centric.
Just a thought.
Note on loop area.

You are very clear.Maybe I wasn't clear earlier...all my gear gets powered from a single balanced power box...and not the house wall outlets.
IOW...the box is plugged into a dedicated 20A outlet...and then it distributes power to all my gear...so everything is grounded back at the box.
TBH...the article you linked to is pretty confusing to follow with all that "Zero Loop" stuff and the diagrams. In a nutshell, what you want is a "star grounded" system, where all gear is grounded back to a single point...my balanced power distribution box. The whole purpose of the balance power box is that it eliminates those voltage differences and creates clean power.
Also...I totally don't understand his logic of running the power lines 100% parallel and in such close proximity to his audio lines...???...at least that's how it appears in the drawing and the images of the conduit installation. That was always considered a bad idea and if you must run parallel, you need to keep a good 2' distance between them. I have always kept my audio lines away from power lines when I had to run them parallel, with only the occasional crossing points where they need to meet at the gear. That's something I learned a long time ago...so his "keep them close" thing doesn't follow that at all.
He says that you "collapse the loop" by simply bringing audio lines as close as possible to electric lines...Huh???
I feel like there's a whole page of detailed info that is missing in that explanation, and it really makes little sense to me.
If anyone can interpret what he is actually talking about...please post up...but for now, I'm following my star grounding and keeping the audio and power lines well apart.
This will be my third, more involved, studio wiring setup...and I've always followed the star grounding system to the best of my ability...and actually, this will be probably the most cleanest yet, since I am able to run my own distribution lines, rather than having to make do with house wiring.
I've not ever had any real ground loop issues on the whole. Sometimes with a guitar amp and pedal, you get something weird, but it's usually fixable at the source...otherwise, my console, rack gear, and recording equipment have always run dead quiet.
Sometimes it's down to an individual piece of gear and how it was wired internally with the signal ground and chassis ground...but that too was an individual case that could be fixed.
With this new studio, I will be rewiring at least 60% of my patchbays with new cable...so there is where extra attention is needed, since I'm going to be re-soldering a lot of connection points.
You are very clear.
Just trying to be helpful Miroslav.
If you are a stickler for code compliance note that symmetrical power is not code compliant for domestic use.
Would also think anything after that would not be up to code.
Great when it works until it doesn't.
FYI for all.
How are you going to be heating/cooling the studio?

If you have the skills to do it and patience to source the parts, it's brilliant stuff. And you can customize them for your own space's needs. Just sayin'!
Personally, I don't mind having snake cables running across a room, especially a live room; I think that looks much better than a bunch of loose cables running to the wall. Also, if you use snakes, I would not connect them to wall plates; that's just more expense. I'd just build a pass-through in the wall between the live room and control room and run the snake cable through it and then terminate it at a patch bay.
