Electrical - Romex Wiring and Other Recommended Enhancements

Based on everything I have read it sounds like I should:
1. Use 20 amp circuit breakers in the electrical box
2. Use 12/2 wire
3. Have electrician drill separate holes for each wire ran to/from box (at least 1.5 inches a part)
4. Have dedicated /separate circuits to avoid ground loopsquality breakers
5. Purchase good quality breakers, ABB is the preferred brand   
6. They should stay on the same buss bar to avoid ground loops

I have not measured but I am guessing about 20' to 30' from the electrical box to the location where the plugs will go. I plan on using my  cruzeFIRST Maestro Outlet plugs in the home I am closing on this Thursday.
My equipment is Primaluna Dialogue Premium Integrated
Lampizator Amber II DAC
Opportunity 105D
Auralic Aries streamer
High Fidelity Cable Hemisphere

One of my main concerns is not to do anything that could fry my equipment.  I believe with the above I should be okay.  If anyone sees any concerning issues please let me know.

Thanks all for your assistance and feedback!

I'm being told by someone I trust that 15A breakers are far more advisable to avoid the chance of frying wire and house fires. I'm no EE but think that it is true that just because an amp or preamp has a 20A IEC receptacle does not mean you need to feed it 20A for optimum performance. Under all but the most unusual circumstances, your gear will get all the power they need with a 15A breaker. At the end of the day, the capacity of the breaker is about convenience-not having to worry about the breaker tripping. The trade-off is that the higher the amperage of the breaker, the less protection you have. I would rather have the inconvenience of resetting the breaker and the peace of mind. As an insurance lawyer, I have seen first-hand that house fires have occurred due to unnecessarily high amperage breakers.

... 15A breakers are far more advisable to avoid the chance of frying wire and house fires. I’m no EE but think that it is true that just because an amp or preamp has a 20A IEC receptacle does not mean you need to feed it 20A for optimum performance.

I can’t imagine any preamp requiring a 20A line for sufficient current, but there are certainly some amplifiers that do. And an amp that requires only a 15A line might still be better served with a 20A line, because the heavier gauge wire on the 20A line will suffer less voltage drop.

Not so. The capacity of a breaker is defined by the gauge and length of the wire on its circuit. The purpose of a breaker is really to protect the house wiring. Provided the wire is properly sized, a 20A line and breaker is as safe as a 15A line and breaker.

There is absolutely nothing wrong with using 20 amp breakers as long as you run 10/2 wire.
Yes, there are preamps and amps constructed for 20 amp IEC's, it is possible that if you use a 15 amp breaker the product might lack its full potential.
If you are going to use an HFC Hemisphere then I would suggest you use a Furutech GTX-D NCF (R) outlet and not the cruzeFIRST Maestro outlet to power the Hemisphere.

Not necessarily. It depends, in part, on the length of the run from panel to receptacle. If in the US, check NEC.

You are correct; longer runs could require a larger gauge.  Always best to check NEC code.
