Install a whole house surge protector, and at least two new 20 amp dedicated circuits for your equipment. Maybe $1,000 or less, to get you to better load capacity first, before buying other expensive equipment. I just got done installing 4 dedicated 20 amp circuits for my Mcintosh amps, controller, and new REL sub. Wasn’t that much more money for four circuits, then just one,
Does and don't
Can I plug 2 bryston 4b amplifier into a furman 15 amp regulator? It's furmans small regulator.
