Two 40-amp circuits, one per monoblock

When I moved house, power was non-negotiable. Two dedicated 40-amp circuits, one for each monoblock. No more one circuit shared by everything.

Here's what we did. New lines pulled straight from the main power board with thick copper cabling, each MC611 taking its power independently on its own circuit. The low-power devices, the C12000 preamp, the DAC and the sources, share a separate circuit filtered through the IsoTek conditioning I have always had.

Everything terminated on brand new points and switches, with no reliance on pre-existing wiring. In the old room, one electrical circuit fed the entire system. I never want to go back to that, and I did not want to inherit somebody else's wiring either.

This was not about curing a noise I could hear. It was about the foundation: giving each monoblock its own supply and taking old wiring out of the equation for good. The electrical work went in while the room was open for minor construction, with the crews running in parallel. After installation I gave the new circuits 10 to 20 hours before the first critical session.

Power in a house is decided once, while the walls are open. I decided it before I decided anything else.
