I always thought that was why they were called white papers.

I listened as well. Try the test I used:As someone with both an academic and industry background in networking, I can sympathize with this skepticism. Not that many years ago, I too scoffed at the notion that any part of the chain of digital components upstream of a DAC - not just switches - could have any impact on SQ. It was only when I actually took the plunge and started listening to gear that I realized the upstream chain could profoundly affect - both positively or negatively - the SQ of the system.
As a practicing network engineer and architect I find people claiming "A background" in any such thing to be dubious at best.

As someone with both an academic and industry background in networking, I can sympathize with this skepticism.

It was only when I actually took the plunge and started listening to gear that I realized the upstream chain could profoundly affect - both positively or negatively - the SQ of the system. On the networking side, this includes switches, routers, and even Ethernet cables, which I admit I found very disconcerting. I did my own experiments using OS monitoring tools to look for errors, retransmissions, or any other indications of functional misbehavior, and found none. All I could conclude was that we were hearing some orthogonal phenomenon - unrelated to the actual digital function of the device - which was not yet understood.

I had to check because I had forgotten: yes, the Uptone does cost $640. All that for doing nothing (if you're lucky!).Unwittingly and unsurprising they wrote a white paper that defeats their own product:
Low/High impedance leakage currents: Great use WiFi or Optical. Both are faster, less expensive, and offer far more isolation than your 100Mbit only port.
High speed, low jitter clock: Ok then simply use a playback system that takes advantage of as much wire speed as can be provided. In my setup that was a 480MB album all transferred over to my computer using JRiver in less than two seconds. The entire album played with the network cable unplugged.
the eR: $640
My 10GBe setup (server nic, workstation nic, fiber transceivers, Cisco 2360 with 10Gbe) all in was $210 and I was getting 332MB/s on my lowly Celeron 3150 based system.
AC-REGEN device to de-jitter AC power? Air molecule ISO, to block air molecules from hitting the ear drum and increasing noise floor? Quantum REGEN to eliminate vibration and jitter at the elementary particle level? I dunno. It's going to be exciting, whatever it is.

UpTone Audio EtherREGEN Review and Comparison
UpTone Audio EtherREGEN Review and Comparison Rajiv Arora Introduction The UpTone Audio EtherREGEN (shortened to eR for the rest of this review) is a diminutive Ethernet switch with a bold value proposition. UpTone claims it “...is capable of producing surprisingly audible sonic improvements in f...audiophilestyle.com
Summary
The UpTone EtherREGEN is one of those rare products that delivers high-end audio performance at an affordable price. Not only does it deliver “surprisingly audible sonic improvements” as claimed, it holds its own against the best-sounding competing products out there, that cost 3x its price or more.
Furthermore, unlike any of its competitors, UpTone have attempted to demystify the technical basis for the product, and are to be commended for that. Whether or not it convinces the skeptics, I for one applaud their transparency in the matter.
For a modest investment, users can start with the sonic benefits out of the box, and extend these benefits further over time with upgrades to the PSU and clock. With this stepwise approach, users can achieve similar absolute performance as the best of the EtherREGEN’s competition.
I don’t use the word “bargain” lightly, but in this case it’s true. The EtherREGEN is one of high-end audio’s bargains. If your audio system uses Ethernet for streaming audio, you owe it to yourself to try the EtherREGEN.
