"This hardwire connection can help tame the buffering issues that wireless connections can sometimes generate. In my home, the router is located two floors away from my listening room at almost 40 feet."

That's because he didn't setup his wifi properly. I've killer coverage with an average of 300mbps (38MB/s) with my, per Chris Connaker, cheap ass TP-Link Omada 1350 AC ($56 X 3 of em).

If he has a hardwire to that room for the SR EUM then he has a hardwire to put in an AC1350,1750,2400 or AX access point (aka wifi 6).

The connector design with a single LED behind a small hole is rather unusual. Of course, they could have both chosen the same one by random chance.
Ah, having looked at a higher-res picture, I see what you mean. It'd be hilarious if that's what they've done, rather than getting their own $2 PCB developed.

The ports of that 2300$ switch are indeed a perfect fit to the 14$ TP Link:

I'm pretty sure it's just the TP Link in a different case with built in power supply.
Well, that's probably better than that company attempting to build their own switch.

That's not far from being fraudulent.


>90% of the added bollocks is in the marketing schpiel, starting there with "billet." (Very familiar to me, bike performance parts. Often used together with "mil-spec" and "aerospace".)
At least for bike parts billet gives you a stronger part with decent grain orientation compared to cheaper cast and post machined part. In a switch box it's utterly utterly useless.

To their "credit," they did remove the power indicator LED. That's just got to make a difference.

You think? What do you bet it's still there, they just didn't poke a hole through to it.

Except in Audiophile La-La Land. Where grainy is bad but grain-aligned copper wires are good.

Don't hold your breath. It's well known that that etherregen does nothing for Any competent dac.

On another forum a member today recommended the Melco S100 switch, a USD 2,800. I suppose he would say that the $640 EtherREGEN just wasn't high enough quality to make a difference by comparison.

Interestingly a review with purported lab results suggests that the device might be superfluous with better quality DACs. ;)

Fell down a rabbit hole an hour ago and of course ended up here. Man, I love ASR! Only on page 4 here and have solid expectations this should get better. Just hoping Uptone represents and tried to defend this grift.

I have a lot of large hospital system customers (I deal with mostly fortune 500 type clients in general). Let's just say that getting FDA certification for network attached patient monitors is a non-trivial exercise for vendors. The technology is not going to be the latest and greatest and this stuff is not cheap. I'm not personally sold on ethernet isolation as something needed (and I deal with packet analysis solutions for security and operations anyways across all verticals - I'm not a health care specialist - just happen to have some big hospital systems as customers) but spending 100 extra bucks on a patient monitor that runs 5 or 6 figures on the theory that it could at least marginally improve patient safety seems orders of magnitude less silly than these audiophile applications.

Keep in mind that part of this is CYA from medical device vendors as well who will recommend things like "ethernet isolation" regardless of whether it's really needed or not.

My larger point was that medical grade ethernet isolation - which is designed (in theory) to improve patient safety - is still WAY cheaper than audiophile nonsense.
I designed this - You can see the 8mm patient barrier and the Y rated cap.

Vid of me machining the end plates of the first 20 for testing

We had to go thru some pretty rigorous test at Welch Allyn to get this approved for 60601 and EMI. The first one we did the W/A guy rec'd a chip that Lady Ada uses in her USB Isolator. Before Sanjay took it up to NY to W/A' EMI lab I mentioned that we should do a pre-qual. Turned on my spectrum analyzer and powered it up. The thing had as much RF as the SS radios we did for Hanscom AFB... good lord.

The EMI test guy at W/A came out, shook Sanjay's hand and mentioned it was the highest radiated emissions they'd ever seen. The W/A guy that suggested it laughed and said oh, well better on your nickle...

Ended up using a simple 19kHz design common in 422 power isolation. That low a freq its harmonics are well below what they care about. We did have add an additional common mode choke on the USB (to get the customer equipment to pass).


They still sell this thing... https://www.homscales.com/c-homwa-1/ wireless version: https://www.homscales.com/pelstarone/

As to Ethernet - the transformers used on 10/100 and gigE provide galvanic isolation. See attached... Tho it may not qual for the 60601 isolation spec...

And a 22M bridging resistor (R2) (which won't carry too much current, though). Normally, the RF bridging EMC-cap (which value?) is something we're trying to avoid in true galvanic isolation, isn't it?

We have spelled it out. We have shown how we deal with it. We have measured it. We will, when ready, publish some of those. But it won't matter to you flat-earthers. You are on the wrong side of history here people. :cool:
We flat-earthers , on the wrong side of history , are waiting for 2 years now for exact measurements from the house of Brothers Grimm (Swenson- Superdad).
