Correct for the most part. I just wanted people to realize that prioritization is a thing on modern networks. Time delay sensitive data is managed.

How did you control for sighted bias in your tests?The measurements do not show a difference but the actual sound reproduced with the EtherREGEN was improved.
That OSI terminology is decades past its expiration date.Q/CoS at Layer 2, DSCP at layer 3.

We could have many debates about audio gear performance. In this case though, no argument even rises to the point of debate. This device cannot, and will not make an audible difference. I will bet you any amount of money that the sound has not improved.I was still in the 30 day audition period and was actually hoping to not find an improvement so I could send it back, save money and reduce my box count but no. After hearing the improvement I could not listen without it so it stays.

I implore you to perform the above test I suggested blind. Have a loved one switch the cables for you when you are turned away. At stake is $640 and lifetime of new outlook on audio performance. Please don't let the opportunity pass you buy. It doesn't get simpler and easier than this scenario.
I haven't heard these ethernet transports, But I always thought the concept was a little silly - in terms of things sounding better. Ethernet packets transmissions are simply immune to jitter. Otherwise we wouldn't be able to have 4k streaming video or pretty much the entire internet. I think you very thoroughly explained that there could not possibly be any kind of measurable difference as there literally isn't any.Most excellent. Thank you very much.
Don't you people understand anything2. He says some of us don't listen. I listened. I heard no improvement.
Have you never heard of Schrödinger's cat5 cable ?
But you can not be sure it has disappeared until we all lookMy cat shredded mine then disappeared.
That is the native Roon streaming protocol. That is what I used in this review to stream to Matrix DAC. I have also used it with other streamers in other reviews. It is one of the best streaming protocols I have seen as far as reliability.Do you think you could perform some sort of measurements on Roon's new certified transport mechanism I think it's called RAAT.
I called my audiophile friend and he is coming over tomorrow. We will conduct the blind test on each-other and let you know the results.
Good report.That was interesting.
Blind testing the ER against a "generic" Netgear switch.....two of us were not able to consistently pick one switch over the other but there was a slight preference for the ER in the overall results. We just could not reliably pick the ER out each time. Doing a "sighted" test I did have a preference for the ER each time.
I have Kii Three DSP active speakers that up-sample the incoming data and process it with proprietary DACs / DSP modules. They sound very good with just about any input. The built-in power filtering renders the Kii immune to external conditioning and cable swaps.
Bottom line: The "sighted bias" is a real phenomenon that must be addressed when testing. Also, audiophiles like to tweak their systems which explains the availability of all the gadgets to try - some more effective than others. It's a hobby that we enjoy.
When you make a change to your system, if you think there is going to be a difference, you will hear it. Your brain hyper focuses on the music and now digs deep to hear note decays, silent background, etc. All of a sudden a "veil" is removed. Detail becomes luscious and more "analog like." More lifelike.
Now being assured that the change made a sonic difference, you go back to the old setting assuming it is going to sound worse. And worse it will sound.
This has happened to me countless times. I too can swear there is an improvement and a big one. Then I realize that what I thought could not have been there as often, I realize I had not made any changes!
Play a piece of music once. Then go back and play it again without changing anything. But now focus on it to hear more detail. And more detail you will hear. You will hear it even though I just explained, and you know there can't be a change. Yet there will be.
The common retort is that people hear these differences when they are enjoying gear, not testing it. Problem is, they make the initial assessment when comparing gear, not enjoying music in a laid back position.
With the effect not being real, it will wear off. Then comes the next tweak/"upgrade" that triggers the cycle over again. Take notice that the people who "hear" such impossible things, have tried and swear by many impossible tweaks. The ethernet cable. The power cable. The stand. The footers. The tweaks to the OS. The special media player. Heck, even what SATA cable is in the computer!
They are living an illusion and simulation and not able to step out of it to see the reality. They could if they just listened to us once. Just once perform the same test blind. Alas, just like the movie matrix, they don't want to know. Knowing means eating crow. And eating crow is not what folks rather do with online reputation.
