Looking to set up separate circuits for my system

I used this doc in my power upgrade: https://forum.msbtechnology.com/t/in-wall-power-improvements-for-high-end-audio-systems-its-big/300

• 8AWG copper braided hot & neutral 28’ runs, cryogenically treated
• 10AWG copper solid ground, cryogenically treated
• Furutech GTX-D NCF(R) Ultimate Nano-Crystal Rhodium-Plated AC Duplex Receptacles, cryogenically treated
• THQL1120 - GE - 20 Amp Circuit Breakers, cryogenically treated

The result was a very noticeable improvement in clarity and microdetails. Well worth the $5k upgrade.

I would recommend something a bit between @elliottbnewcombjr ​​​​@goleksiak 

Run 10 g dedicated lines, one for digital and one for analog.  Electricians will tell you 12g is fine.  Use 10.  I did this and ended up going back and running two more, so 2 for analogue and 2 for digital.  I use less than the 8 outlets that provides but more than the 4 that two runs provide.  Don't just run one wire, two is little more trouble.  For me:  Analog: two Amps and a Preamp.  Digital : DAC, Streamer, Clock.  

Keep the audio lines on the same leg of the box so the grounds match.  Keep the audio lines OFF the leg with big stuff, especially HVAC.

Lots of outlets to choose from; I was not a fan of the fancy Furutech outlets, and recommend upgraded ones like Hubbel or PSAudio which are reasonable.

8AWG wire isn't much more expensive than 10AWG - I needed 180' and it only cost $120 more to go from 10AWG to 8AWG. The trick with 8AWG is the only outlet that will natively accept 8AWG is the Furutech GTX-D NCF(R) and those are howlingly expensive. You can pigtail 8AWG down to 10AWG for use with a normal outlet and that is acceptable practice code-wise. 

I have found separating the digital and analog front end gear beneficial. I have four dedicated lines with four dedicated circuit breakers for audio only, one for each mono amp, one for analog and one for digital. All four dedicated lines use steel case MC cable 10AWG solid copper. I prefer the MC with metal boxes for better shielding. I would run at least two dedicated lines with two dedicated circuit breakers, depending on your total power consumption requirements.
