To extend Ethernet to remote location, are Powerline extenders or Mesh systems better?

I used to have my ROON Core behind a Powerline network. I also had my living room system’s DAC streamed via this same PowerLine. I even have this PowerLine in my garage with a bunch of heavy-duty computer servers.

When the new George Harrision remaster of ALL THINGS MUST PASS in high res came out, I was getting some distortion at a particular part of a track, when George was whistling. I could ALWAYS reproduce the problem at the exact time in the music. So, this was very helpful for me to figure out the cause.

It turned out to be my ROON Core being on the PowerLine network side of my home network. I guess the Powerline’s bandwidth could not keep up to speed with the whistling bits. So, I moved the ROON Core machine to my non-Powerline part of my network and the problem was solved.

I now forgot if my living room system has this issue still, since it is on the PowerLine as a ROON-READY endpoint. I do not think so, which is interesting. I confirm this with another post.

PowerLine works for me when the ROON Core is in the non-PowerLine part of my network.

@yyzsantabarbara wow... i have heard that same sort of distortion at times in my system, a sort of ’brownout' on the upper(usually) frequencies.... i am sure it is caused by the main internet connection or my ethernet network...

Hello,

I found out that Nordost has this QBase power supply system that powers 4 QPoints and two other selectable pieces like a Roon Core and maybe your DC powered tt. I realized at that point that some of these Roon products are DC based power with basic switch mode power supplies or wall warts. If you are not doing the Q Nordost products then maybe get an SBooster linear power supply for you Roon. The SBooster is nice. When you power it down it can take a minute for the green light to turn off. This means there is a constant power to the Roon unit or your favorite DAC or piece of gear. Computers do not like interruption in power. This SBooster could really solve a lot of Roon issues. Plus you should get better sound. You do have to order the correct power output when you order one. These are sold all over. If you are in the Chicagoland area this store is a dealer.

So if you want to take out some of the Roon headaches and improve the sound for around $400 this seams like a no brainer. 
I hope this helps. 

My issue was related to the extra bandwidth requirements of hi-res. I had no issue in the past with non-highres. However, now I have solved the issue for highres.

Oh, yeah, Roon core really consumes the Wifi bits.  The issue is that it has to read and write at the same time, which bogs it down.  I keep my core on wired Ethernet and the devices vary from wired to Wifi.  All is good this way.
