Network Switches

great thread, recent posts are an incredible sourcebook for improvement investment…..

I have had an Orbi mesh system for a couple of years now.
Although I run fiber from my main router to my main system and that works great, I operate my garage/outdoor system through one of the mesh satellites as described by @david_ten below with a 0.5M CAT8 cable from the Orbi satellite to a Metrum Baby Ambre then Jade DAC and it too sounds great with no issues (drop outs, etc.) whatsoever.  I use the stock power supply on the satellite with no perceptible detriment to SQ but I do use LPSs on both fiber converters associated with my main system.

Recently added network switch, has imposed sound signature. I received expected benefit of lower noise floor, more detail, resolution, transparency, didn't expect so much or any impact on the quality of sound. Just a bit less natural sound than prior, like a layer of electronic scrim added, quieter, yes, but like a haze added. I've improved other network equipment and cables in past, don't recall this much impact on sound signature.
So, in your experience, have network upgrades affected sound signature? I'm burning in network switch, new ethernet cable as we speak, eliminate this as culprit. I'm also going to try various power cables.

The only times I've had network gear affect sound quality seemed to be related more to their power adapters and whether they are in or out of the cleaned power zone. 

I've heard that prior to using LPS and power conditioner on every single network piece. I'm also thinking perhaps the signature thing was less noticeable in past since streaming solution not as mature, advanced as now. Past upgrades improved noise floor, resolution to such an extent, all my attention went there, not so much on sound signature.
This haze or less natural sound is a subtle thing, but still exposed on present extremely high resolution system. I know theoretically, network equipment shouldn't change sound signature, yet most of us have experienced theoreticals being broken.
I do know a lot of these audiophile switches use generic switch circuit boards with upgrades parts and LPS added. Perhaps I'm hearing generic board liabilities. In any case, it will take a few more listening sessions to get to the bottom of this.
I already know about placebo effect, expectation bias,  and how to adjust, this not the deal here.
