In my listening tests, ethernet always beats wi-fi. I don't have any deep understanding, but I have read explanations as to why:
1. A wi-fi receiver receives all the wi-fi signals inside the home, and from outside the home from neighbours' systems. The correct address for the actual device has to be separated out from the various signals that are present. This extra processing causes digital noise. Ethernet sent from a switch is already sorted by the upstream switch, therefore less processing required in the device closer to the DAC.
2. A wi-fi radio is a digitally noisy device, and digital noise gets folded into the data signal. Wi-fi waves can also infiltrate cables and components in the audio system causing RFI.
A wi-fi system is galvanically isolated, which is great, but the above disadvantages overwhelm the advantage of galvanic isolation, IME. Fiber optic combines the advantages of both systems, but that's another story.
When I've compared wi-fi vs. ethernet cable, the biggest difference I hear is a more solid or present sound through the copper cables. The sound from a wi-fi system is more ethereal.
Hello and good morning to you,
@audiobomber. I am assuming that your modem/router is in very close proximity of your source gear?
My experience differs from yours BUT, I do have a possible different situation than yourself when testing. My modem/router is about 90 feet away from my source. There are brick walls, interior walls and other obstructions that present "issues". After flying through multiple thousands of dollars worth of experiments/gear, my best case scenario was to upgrade both the cable modem and the router to a mesh system. The E cable between the modem and the Router is a Shunyata Alpha with the C-Mode filter on the cable itself.
I have a very extensive and rather complex setup upstream of the streamer but in my particular case? Wi-Fi beats out any configuration I had ever tried with hard wired. I have 3 moats total that isolate any upstream noise, plus two more C-Mode filters and then the Muon Pro along with a plethora of other noise reducing kit.
The mesh system communicates to and from the router on a completely separate band than that of the rest of the house and I have prioritized the 2.4Hz to only run the streamer with a non-limiting 1Gb port. Everything else in the house runs on the other bands. With a 100' Ethernet cable (
regardless of type), I found the sound to be not as good. My guess is that over a 100 foot run, the E cable picked up noises along the way and getting a 100' Shunyata Omega or like cable would prove to be way too expensive to even try out.
I know that there are many different configurations and ways to clean up the noise and while I may be alone in my thoughts on this. I do not believe that there could ever be a single, solid and concrete way to optimize a signal to the source. There are way too many variables within people's systems that would sway one finding/observation to another. In my case, it is distance, obstructions and the noise that the E cable picks up along the way when hardwired.
Yes, I do know that I could simply move the modem/router closer to the system but I would have to turn around and move it back to where they are now when the new stereo room is built out in the current shop (separate building), otherwise, the signal would have to travel around 140 feet and two more exterior brick walls, plus be exposed to outside elements. Where they are located now, I will simply get another satellite for the mesh system and the distance would be reduced to about 35-40 feet.
I might entertain the thought when it's out there to install RG-6 cable from the road to the new room, place the modem and router in the new room and beam all other signals to the house. But for now, I have no noticable deficiencies running things the way I currently am. Time will tell.
