Good advice here from @Soix, @audphile1, @Lalitk, @ghdprentice, @ghasley and others! If this was discussed I apologize! I would scrap the wall plate. It is nothing but a cheap connector stuck in a wall plate. You can remove the plate, disconnect the wire in the wall from that and then do much better. I like the JCAT Net Isolator as a good coupler. There are others. For esthetics you can pop out the stock connector and run the wall cable through that hole. Then I agree the cable from there to the streamer is most important I use a Muon Pro Ethernet Filter System which has their high end ethernet cables on each side.
Ethernet cables
Long time audiophile here but, more of a rookie regarding streaming. My basic question is should I upgrade my ethernet cables and what price point would be reasonable for my application.
The streamer is in a secondary system and is used only for casual listening. The streamer is hardwired to the system. At this point I do not have a streamer in the main system.
Below is a list of the gear in system 2.
The streamer is a Node 2i with the power supply upgrade from LHY (a DIY kit) sourced from Beatechnik out of Singapore. Not using the internal DAC but, feeding the digital signal to an outboard DAC.
DAC - Luxman DA-06
Preamp - Simaudio P5.3
Amp - McCormack DNA-500 (yes, way overkill power wise for the system but, I love the very relaxed sound of this amp)
Speakers - Dynaudio Contour 30i
Cables - Primarily Transparent Ultra mm2 generation.
Internet is from my cable provider via coax cable.
There are three short cat 6 ethernet cables (5'). One going from the modem to the router, one from the router to the wall connection for a 100 foot cat 7 run in the attic and one at the system end wall connection to the Node. The short cables are Amazon Basics cat 6. The 100 foot cat 7 was sourced from Amazon with one of those never heard of names - Snanshi which, seems to be fairly decent but, I wouldn't really know.
So, do I upgrade the Amazon Basics cables and if so, what would be a reasonable choice?
