Dedicated power circuits

If you are already going with the Cutler Hammond brand I would checkout adding a Sorcer Apprentice at the breaker box:

Sorcer Apprentice

The Apprentice also changes the quality of the AC line starting from the circuit breaker box throughout the home or commercial space. It does not employ filters, isolation transformers, AC line regeneration, nor balanced power techniques. This harmonic resonator uses small line transformers connected in series along with proprietary digital amplifier circuitry under algorithm control. The AC line is "re-referenced" or pulsed with low frequency harmonics to increase the S/N ratio.  Uses 4 AC transformers.   

• 110/220 VAC 50/60 Hz
• Installs at AC breaker panel or near audio/video system components
• Dimensions: 17" x 11" x 3.0"
• Weight: 22 lbs.
•  

You can send this video to your electrician for review:

As for the receptacles I like pangea:

Hello @gphill , Here is what I know or think I know.

Receptacles: Use an audiophile grade outlet.  I used PS Audio, reasonable and grip great.  I hear mixed reviews about the expensive outlets; some like them some do not.

Wire: 10 gauge.  The electrician will tell you 12 is fine for 20 amp outlet.  Use 10. Sounds better.( I have been told by someone I believe).

Breaker:  I went standard here, but did use some silver conductive grease when installing.

I think dedicated circuits are very worthwhile, and you are correct; one for the amp and one for the front end / digital.

My final advice:  Run three.  do it now while easy.  You never know...monoblock amps, other stuff.  Ask me how I know this!

Thanks for all the responses. The Torus all in one looks interesting but at 18k it ain’t happening. Because of local code I’m going to have to use tamper resistant outlets which I will replace after the job is finished. Any special wire from the breaker box to the outlets? Any special breakers?
