Dedicated power

Running a dedicated line for your system is a major upgrade that does not cost a fortune and the sound can improve as much as a component upgrade.

Yes, do run 2 lines.
One for analog and one for digital.

I recently did this. I got better focus on my bass.

As mentioned no need for 30A. Run two 20A lines with 10ga solid copper. Run them on separate legs of the panel. Run the romex at least 12" apart...no staples...use cable hangers.
If the cross other lines have them cross at 90 degrees. Run them to plastic boxes. Use hospital or audio grade receptacles.

Also, when you set up your components, don't run your AC or signal cables parallel to each other. Have them cross at 90. These little things matter.

@mofojo:
Run a 10/awg BX/MC cable solid core conductors from the breaker panel to a metal receptacle box. The metal sheathing on the BX/MC cable absorbs the (EF)) electric fields emitted by the wires and shunts it to ground. Now from panel to plug is shielded. The upside is low line noise and reduced antenna effect. Downside BX/MC cable is pricier. Hope that helps. Mike.  

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!

Extreme isolation transformers don't "bring noise", they are specifically designed to reduce noise, and transformer hum is a mechanical noise that doesn't necessarily translate into signal stream noise.
