Has anyone tried the new Synergistic Research UEF Performance Enhancer - Ethernet Filter?

For copper, digital zero is <300mV, digital one is >3.8V. That means anything below 300mV is ignored. Plugging into an unused switch port is ignored because the switch is 1) ignoring a passive component component. 2) Because a switch only allows one port to port connection at a time. This isn't up for discussion. This is just basic Ethernet operations. When you bounce any Ethernet tweaks or cables against reality, there's nothing there. 

I think all these Ethernet discussions are pretty mind blowing. People who argue for these devices and the companies, know nothing about Ethernet or how related protocols work, not a single person have demonstrated even basic knowledge. This is exactly what these companies count of, and why these companies harass people who perform objective tests, and refuse to have their products undergo any testing at all.

it is super simple, test the product by measuring the output from the speakers. If there is a difference, it will show there, but Uptone, SR and other absolutely refuse to submit their products to this type of testing. That alone, should tell you everything you need to know.

Yawn

I ordered two of these and they should arrive some time next week. I've had good luck with SRs somewhat unconventional products in the past (fuses and ECTs). On the other hand, my ethernet setup is on the other side of an optical network bridge (EMM Labs NS1), and in the past I have heard little difference with Etherregen and fancy ethernet cables with this particular setup. There was a big change from network stuff when I had DCS Bartok connected directly via ethernet, but I didn't like that DAC.

I have come to the conclusion that ethernet brings quite a few digital nasties along, and I have noticed some improvement using similar devices on USB busses.

I also find that the power or grounding systems may also be implicated in this. For instance, my current setup is largely impervious to ethernet cables and Etherregen makes only a small difference. But switching between a copper and silver DC cable from my LPS 1.2 to Etherregen did have some notable qualities. It seems extremely improbable that any change in the signal chain happened, so it would have to be related to the mains or ground noise. Having had a few experiences like these gives me some hope that these tweaks will have an impact on my system, despite the apparent odds. I'm hoping to bring noise contamination down from the system as whole from my router and Etherregen, but I dont believe these will effect the linear signal chain in my case.

We will see...
