I used Powerline Adapters for several years, including the models mentioned by the OP. Eventually they all crapped out. It turns out that in my 100 plus year old home that there are several transitions in zones in the fuse box to get from the router to where the various equipment rooms are, and there is a 40 watt drop across each zone. The Adapters eventually give up the ghost trying to negotiate this. Eventually I bit the bullet And paid a few hundred bucks to have someone ethernet wire the place. The cat 5 is all out of view and everything has worked flawlessly in the years since, with much better performance than WiFi
Comparing Powerline Ethernet to WiFi for streaming audio
Thought I would share my findings.
I have a ROON based music server system with Tidal and Qobuz streaming services. Using Small Green Computer’s SonicTransport i9 Optical as ROON Core, connected via optical cable to a Sonore Optical Rendu (powered by Sonore Linear Power Supply) acting as ROON endpoint. This then connects to Chord Blu Mk 2 via USB, which upsamples and connects to Chord DAVE DAC via dual BNC.
Until very recently, I was connecting my ROON Core to my cable modem/router using Google Mesh WiFi. I was and still is very happy with the sound quality. My audio system is too far from my cable modem to run an ethernet cable from cable modem/router to it. So, I relied on Google Mesh WiFi with a seperate pod situated close to the ROON Core and connected via ethernet. The Google Mesh pod itself had a linear power supply instead of the stock wall wart.
But I just tried a Powerline Ethernet adapter. This uses the home’s internal power cables to route ethernet from one room to another. I always thought that running digital data on power cables was going to be noisy. I bought a NetGear Powerline 1200 (1200Mbps speed). There are more expensive and newer powerline ethernet models available up to 2000Mbps speed. But these come with dual ethernet ports and pass through filtered power outlets. I though for dedicated audio purposes, better to keep it simple and minimize electronics.
Bottom line, I was blown away by the improvement in audio quality of the NetGear Powerline Ethernet connection over the Google Mesh WiFi connection. Mind you, I was very happy with the quality from the Google Mesh kit but the NetGear Powerline ethernet kit was clearly better.
The sound quality improvement was immediate and very evident. More space between instruments and notes. Smoother, more image depth and more air around the notes especially the trailing edges. So, no doubt, the Netgear Powerline 1200 was far superior to the Google Mesh WiFi. I then swapped the Netgear for a similar powerline ethernet product TP-Link AV600. This was recommended by Small Green Computer. The TP-Link is smaller and has 2 pin power prongs. The Netgear Powerlines has 3 pin power prongs, so it has a ground connection to the power outlet. I found the TP-Link to take a step backward in sound quality. The image depth decreased. Soundstage was flatter and there is less air and space between notes and instruments. The TP-Link Av600 was sounding a lot closer to the Google Mesh WiFi. Just my observations, FWIW.

I have been using Netgear power line Ethernet adapters in different parts of the house for the last 6 years. For the most part I have had great success, but learned early on that what works well on one outlet or room of the house may not work so well for another room or set of outlets. So I think that this is case where very much one’s mileage may vary. |
Several years ago, I mentioned to my retailer that I was using a powerline adaptor and he said I should replace it with an Ethernet cable. I said it was ’impossible’ because my living room is on the opposite side of my house from my router and there is no way to install the Ethernet cable. He explained that even if I have excellent electrical wiring in my home, a powerline adapter can never be as reliable as an Ethernet cable. A powerline adapter lets the signal travel through electric wiring, but it is still not a physical connection between my computer and my router, like an Ethernet cable is. A powerline adapter is an EXCELLENT option for hard-to-cable structures or where installations are too costly or time-intensive. Plastered walls, brick or cinder block can present a formidable challenge. I asked the retailer to inspect my house and he said they could run an Ethernet cable under the floor, in the crawlspace, from my living room to my router. He went on to say that an Ethernet connection would result in a much better sound quality when streaming music from Tidal, Qobuz, etc. The retailer installed the Ethernet cable and I have to agree the sound quality was much improved. I hope this helps. |
