Digital isolation between Ethernet hub and streamer

@audioman58 So what do you think that a "filter" does to a digital signal?  Don't answer, you post makes it clear that you  don't know.  there is an endless procession of magic boxes that make your system sound like Solti is conducting the orchestra in your living room and this one fits right in line.  Now I've explained my skepticism but I doubt you feel any better.

Filter means to clean ,look it up !! 

I have 4 decades in Audio ,and owned a Audiostore for over a decade 

carlsbad2 what have you done ?  Unless you have  anything of quality or otherwise 

in your system for a few days to actually compare ,to make Any comment without trying ,then you speak out of ignorance .

I can honestly say it does make a SQ difference. I have my Ethernet cable from my router to my Synergistic Research switch then the long thicker cable of the Muon Pro from the switch to my Aqua LinQ transporter connected with the Muon Pro shorter and thinner cable and the LinQ connected to my Weiss 501.Network Acoustic offers a 30 day no questions asked refund if you are not satisfied, so for the skeptical people it is a no brainer. I have been experimenting for years and honestly this is the best i ever had. How can we make a judgement without even trying?

There was a long thread started by Ozzy late last year on the Smooth Lan; seems a few members tried and liked what it did. (myself included)

As far as I can tell, these filters provide galvanic isolation in one of two ways, by either using transformers (i.e., the NA filters) or optical isolation (i.e., GigaFOIL and others).  Don't most good servers/streamers also provide some form of isolation?

The last cable my streamer sees is a fiber optic cable but, even when it was an Ethernet cable, none of this stuff made a reliably discernable difference in the sound of my system, and I have owned the NA eno and muon systems (including their Ethernet cables), GigaFOILv4-INLINE, and others. I could say I heard differences, but that would require talking myself into it, YMMV.
