Network Switches

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.

If I continue to hear deficiency of new switch, along with it's improvements, the question becomes. What would a much more expensive switch like the Innuos bring to the party? Is lower noise floor sole improvement, or are you paying that extra money for something more, meaning more natural sound vs. lower cost switches. Assuming Innuos is superior in any parameter?

Which network switch do you have now ? @sns
