Audio PC

“Is it very expensive to hire an electrician to install audio friendly outlets in your home/studio?”

I wouldn’t hire electrician for changing out an outlet. Watch this video, if you still need help, PM me and I can walk you through over a video chat.

“Is cross talk between PC parts common in terms of creating noise that will be audible through monitors or headphones.”

I wouldn’t worry too much about the internal noise in a PC, they are not designed for optimal audio output in first place. If you want to still use PC as your primary source for audio, try AQ Dragonfly or JitterBug.

Hope this helps!

The big issues tend to be the PC's power supply injects a lot of noise into the AC line, and ground loop noise over the USB connector.

From the computer, I would connect a OPTICAL cable to a external DAC this will eliminate/isolate any electrical noise between the computer and the rest of the system :-)

Build an AMD processor computer.  Add a Pink Faun card of your choice (USB / SPDIF / I2S).  Then get a dedicated linear power supply for the Pink Faun (such as Farad Super 3 or Teddy Pardo or some others). 

I would recommend using a higher end power supply such as Seasonic or similar to get the least amount of noise.  You are pretty much stuck with switching power supplies in a computer unless you try to build a small format music server (there are linear power supplies out there that support PC motherboards).

I built my own Music Server/HTPC and use it for streaming music DSD & PCM and surf the web with the same Windows 10 PC. It has only 8GB of RAM, an Intel i7 Processor (2018 Vintage), and a Fanless Power Supply ( Seasonic X-400 Fanless PSU), and Fanless Heatsink for the i7 CPU. The motherboard is an ASUS Gaming type.

Extremely quiet and as added insurance, I have a solid wire 12AWG/20A AC circuit for the PC & TV while the Audio Rig has a dedicated stranded wire 10AWG/20A.

Hard drives are of the spinning type (1TB, 1TB, & 6TB). It sound good to me. The noise floor is low enough for me.
