I just did this last week. I used two 20A Hubbell Hospital Grade Isolated Ground Outlets. I ran one 12/2 wire to a separate 20A breaker. It was cheaper than one power cable
and unlike power cables, I actually think I heard a difference.
Looking to set up separate circuits for my system
I currently have the following set up:
- Power amplifier-Bryston 4B3 Cubed
- Preamplifier-Conrad Johnson ET7 S2
- Lumin U2 mini streamer with LHY Linear Power supply
- Weiss DAC 204 with a Modwright Linear Power supply
Looking to separate my system from other appliances. In short, not looking to have my system on the same circuit as my refrigerator. I also listened to a 4 minute You Tube Video by Paul McGowan of PS Audio and he recommended that components should be on separate wires not just separate circuit breakers. He also suggested that one can combine certain components together, for example streamer and dac together, preamp and power amp together. Not sure on how to proceed. Yes I will hire an electrician, but I believe that it will be my responsibility to advise him how to proceed. If I have a specific wish list I am sure he can carry out. Any suggestions would be appreciated.

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
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. |
