Ethernet over power line - noisey?


Have any of you actually tried using Ethernet over power lines in your home? Did it affect the sound of your stereo or cause other mischief?

In these discussions on Audiogon there has been mention of this issue but I've not found any actual users describing their experience pro or con taking into account possible effects on power quality and hence sound quality.

Here's your chance!

I use it in both of my systems and I am unaware of any audible effects, even when I turn it on/off/on.

I use it for audio - a NAS in one room with one adapter, another to a Mac Mini connected to my DAC. I did get some network lag at times, which required some network tinkering (prioritizing traffic between the two powerline adapters in question, as I have another elsewhere, which helped a lot). I also use software capable of memory playback to minimize whatever is left. I'm very happy with the results.
