Anybody want a laugh?

So really nobody here has stepped forward and actually tested the highly modified switch manufactured or rather upgraded by a highly respected audiophile products seller. Snake Oil, snake oil.

The same switch which actually has these reviews...
as well as computer audio forums..

On the other hand, I also saw this review,
https://alpha-audio.net/review/review-fidelizer-etherstream-switch/2/


"Now we are curious what a nicer adapter would do on the SG110D-08. So the default switch. We’ll take a Sbooster 12-volt version and connect it to the switch. Poe: Yeah… that’s a step. And to make it even nicer: he immediately plays away the Fidelizer Etherstream. The Sbooster immediately brings an extra piece of peace and control. More than the Etherstream. Those who buy smart can find a Cisco for 40 euros and with 329 for the Sbooster you are 30 euros cheaper. Not good news for the Etherstream."

“Peace & Control”. 

Please, Rix, if any of us were to actually listen and confirm these findings, WTF would we be listening for? 

Don’t you see the problem with the use of these nebulous superlatives?

Yeah I'll agree that the "Peace & Control" verbage sounded quite a lot like bovine excrement.

However I did find the article that stated a good linear power supply into the switch yielded a better result.

I've not heard the switch you linked but I did buy an Etherregen switch and heard an obvious improvement in my system. I then changed the power supply to the Etherregen to a Paul Hynes PR3 regulated linear power supply and heard another obvious jump in sound quality in my system  I then put my old cisco 2960 switch in front of my Etherregen and another jump in sound quality..... 

I wish these things didn't make a difference but experience tells me they do.
