ETHERNET CABLES

@jerrybj 

Then I found out that you can use a phone cable for ethernet, so got my electrician to change the plugs. That was a problem solved.

Wait, what?! Please explain.

Extended the house in 2009, and had a telephone line put through to the lounge. Most probably Cat 5 cable. Phone is no longer...

Was easy for the electrician change the wall outlet from phone to ethernet cable.

Thanks for clarifying. Glad to hear it wasn't old 4-cond phone cable from 40 years ago.

I've used a similar kit by TP Link between my router feed and Node N130.

The best improvement I achieved with my Node 130 was to replace the AC power board with a DC power board and a 5v iFi audio iPower X Low Noise Power Supply.

I had pops and noises when switching digital sources.   I removed the CAT 8 between Aurender and DAC , problem solved.  Also set up the TP Link rg45 to Optical converters and system is free of pops and noise when switching. 

Someone mentioned CAT 8 is bad for audio a while back.   Apparently the metal shield of the connector can cause problems with audio gear on the network
