Dedicated power

An electrician ran one 30A and 2 20A lines to my equipment room.... Yes, I noticed a difference.

Get the 30A line and plug your multiple outlet power conditioner(if you want one) into it. Or plug one of your amps into it and another into the 20A line. But you really only want to plug your amps into the dedicated outlets and keep your digital components in a different duplex. So, you might want more dedicated lines.

If you need a multiple outlet power conditioner, look into P.I. Audio's UberBuss. I have a home theater system so I incorporated a DigiBuss for my digital components into it. And their modified receptacles.

Triode Wire Labs makes great power cables as well.

Isolation transformers bring noise. And eventually they hum. Having surge suppressor devices at your equipment rack brings noise to the system and raises impedance. Use a whole house surge suppressor like a Seimens RS 100 or 140 at the breaker box and a non surge suppressing power conditioner at the equipment rack for the lowest impedance and noise and a higher dump of instantaneous current on demand.

That is Caelin Gabriel of Shunyata’s advice. But a P.I. Audio UberBuss(with a DigiBuss internally to isolate noisy digital components from the analog components) does it better and way less expensively.
Please find a way to isolate the Digital from the Analog.

Then buy a Triode Wire Lab’s High Power Digital American instead of a Shunyata Omega XC and save even more. Take the money you saved and buy new amps like the Jeff Rowland Model 125 or speakers. WIN!
