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.
