BS Node 2i: WiFi or Ethernet..?

FWIW in my situation my small music room has a very great bass problem at around 61Hz. I have built massive bass traps and lots of other treatment to tame it. However the most successful measure to treat it  was? To use WiFi instead of ethernet. Now it could well be the ethernet introduces some additional 60Hz artefact, it could be that WiFi delivers a signal with a deficiency of signal at 60Hz, I'm not really bothered what it is but the 60Hz booming has gone. So each of our systems react differently in different circumstances and of course what some people consider bass booming some people like. So my observation is that some things just need to be a matter of trial and error. Try it both ways you never know.

I had very occasional dropouts with WIFI on my Node 2i (Amazon HD).
I switched to a Cat 8 cable and have not the problem again. 
I am using a Cullen C7 power cable and DH Labs D750 Coax to CDP Dac.
 

Hi guys, if you own a external DAC, it is better to Connect using Coaxial or Optical ?

thx !

I thought coax sounded better than optical when I connected my Node to my DAC.

Optical was thinner sounding. I was surprised by the difference.

As it turned out, different coax cables also altered tone in my system whereas optical was consistent with a few different cables I tried.

I mostly liked an inexpensive Blue Jeans Cable the most out of some fairly expensive coax cables I compared against. It sounded most natural/neutral.
