Ethernet

Ok I've got the TP link configured into my wifi system powered by an Anker battery pack and.... 

Wow, I do hear an improvement in all areas. Clarity and detail. I already had a super black background. Sounds like everything is just more focused. Imaging is a bit tighter. Like the bass in Diana Krall’s Temptation. The bass is smaller and tighter now, which is good, before it was large and kind of diffuse. That’s just an example. Wow. I’m a believer.

Excellent comments by mswale, all of which I agree with and are relevant to my system.

I currently have a whole house wired with Cat5, but to the theater/audio system there are several switches along the way.  I plan to run a Cat6 cable directly from the Wifi 6 MESH router to one switch which will connect to 12 units requiring internet in the theater.    The router  is connected to a good 1 GB modem, 1.2 GB internet service. I have good ceiling access, making this an easy task.

This is a tweak, and I am not expecting a big difference.  Why bother?  This is a simple and inexpensive upgrade which will also be a step towards future proofing the system when I upgrade the internet service, modem and router.

I purchased a LKS LPS based on your post so thank you for that. I know one could go crazy in filtering. The power supply to the 10Gtek is also a 5v/ ( x 2 of them) I was wondering if there would be any value of getting a second LKS to power the 10Gtek as it has two 5v outs.  The 10Gtek is in the signal path . How does one decide what should be filter and what is ok to use the OEM wall wart ? I agree the noise from the house/modem should be filtered. I guess it comes down to how crazy you want to get with this. Again I appreciate your post. I am always looking for tweeks to make the streaming better.
