I actually use both in the sense that I use a TP powerline for the ethernet connection to my DAC(main floor) but use comcast mesh for roon to connect to my core (computer in upstairs room). Router is in basement. It drops occasionally (connection to roon core) but sounds great. Big house so had to deal with distance issues. Wi fi for my setup for the DAC seemed to not work as well. If you are willing to make the effort you could buy both and do an AB to see which sounds better, then return the device you didn't want to use.
To extend Ethernet to remote location, are Powerline extenders or Mesh systems better?
I am trying to get Ethernet into a listening room that is not prewired, and it is not practical to run the hard cable through the old house into that room. I am planning to use a new music streamer that requires Ethernet connection (no wifi).
For hifi purposes, for passing the music signal, not just for computer equipment, are ethernet over powerline units better, or are wifi mesh router systems (which bring an ethernet port into a room using wireless transfer between the mesh devices) better?
For Ethernet over powerlines, I am worried about contaminating the power lines feeding the stereo preamplifier/amplifier, I don’t know if hifi power conditioners will filter out that super high frequency noise well enough.
For wifi mesh, it seems that the wireless handling of the music signal to feed the remote Ethernet port might somehow degrade the sound and introduce other problems that a connected wireline would avoid.
I am not a person that understands these technologies deeply, so I would value perspectives from others here who are users and who may be technically more qualified to understand this stuff.
