Dedicated power

Well, I think this is overkill, but the suggestion I gave you was exactly what I did for my workshop, running 1 1/2 HP and 2 HP motors. :)

In the basement, the NEC let me run 8 gauge (was it 6?? It was a long time ago) Romex with nothing more than nailed on brackets. No conduit needed. Ran it to a sub panel on a 60 A breaker, and distributed 10’ runs from there.

Could I feel a difference while cutting wood? No... but it was much easier to install this way, and the 4 or 5 dedicated circuits could be run more easily.

We use conduit hard pipe (emt) in Chicago.

Romex has better rejection than loose wires in EMT.
Twisted L-N in conduit it best, but it's a bitch to pull.

@spenav How to wire your house for good power is excellent. It should be required reading.

Adding a whole house surge protector (or go Taurus, etc.) to your to do list something to consider.

There's a Torus on HI FI Shark today. For wire use JPS Labs Power in wall cable. It's 10 gauge but probably one of the best for noise rejection.
When I set up my system originally there was noise that you couldn't hear but it did a number on my high efficiency speakers. Brittle is the best way to describe. Very disappointing to say the least. The Balanced Power Technologies 3.5 Sig + introduced was a huge relief. Later found an Equi=Tech 5KVA wall unit. And balanced power doesn't wear out.
