Maybe spend more time updating the roon kb?
Yeah, I donāt rate.

While there sure is a lot of bloviating and skepticism about the whole EtherRegen thing, they have a 30 day money back guarantee.
So Iām going to order one and check it out.
Why not? The worst Iād be out is shipping.

How would a correct measurement be performed in order to please (or justify) better SQ ?
I also like to hear your opinion about John Swenson white paper.
Been there done that a thousand times. Itās always confirmation bias that audiophiles āwith more money than senseā hear things that āarenāt actually there.ā However, itās miraculously NOT confirmation bias that ASR and his ilk donāt hear any difference when measurements are equivalent, despite the fact they donāt actually listen to any of the gear they test! Not sure why itās controversial that the human ear is influenced by more things than SINAD. A turntable measures infinitely worse than a 30 year old CD player. Are we still going to argue that the CD player sounds better? News flash - those measurements are useful to an extent but do not represent the full spectrum of how human hearing works, nor do they consider that different people have different tastes. Just like how we donāt all like the same tastes, sights, smells, and touches. Itās quite simple, really.
Iām waiting for ASR to start Food Science Review. He can go around to restaurants and order a bunch of food, dump it all into a machine to spectrum analyze it, and proclaim what food is better based on fat content and sodium level without ever eating anything. Sounds thrilling.

Well, thatās wrong, so what else in this post is wrong?
Of course we are. Thatās why CDs killed off vinyl. Only nostalgia brought it back.
Now, reel-to-reel tape, on the other handā¦

Have you read the ASR EtherRegen review?
I agree with the fact that Amirās measurements donāt always show the full story - Iāve seen stuff in his videos that may apply to the US, but not in the EU (discussions about house grounding) and some gear that measured well but interacted poorly with other gear.
However, the EtherRegen is just bull. I consider myself an audiophile and many times I do exagerate stuff and use overkill gear, but at heart Iām a computer engineer and I have a relatively good idea about how networking works. Iāve read the EtherRegen whitepaper and other than noise injected through ground connections (which can be eliminated by using a wireless connection), there is no proof in there on why their gear works. Any decent computer engineer can tell you this.
Then you have people saying they hear a difference as if the human ear/brain combo is a highly precision instrument. It is not. For most people I can play an E note on my guitar or piano, wait a minute (like the time it takes to switch switches, pun indented), and then play an Eb. The regular audiophile will tell me itās either the same note or a different noteā¦ but the ratio is 50-50 because itās all random. Except for the lucky few that have absolute hearing, you canāt tell apart two notes a half tone apart unless you play them one after the other (or you have another fixed reference point). Audiophiles somehow think that if they have spent so much on gear they have absolute hearing.
Also, itās funny how people can trust someone has an interesting in selling something over someone that is completely unbiased (like meā¦ I donāt care if you spend your money in the end, thereās no gain or loss for me).

listening and measuring are not in conflict- the 2 inform each other.

lol stop lying
Then Iām sure he also can tell you why phase noise matters in digital transmission, and why stressed eye pattern testing is used.
Have you tested the EtherRegen yourself ?
Like you, Iāve been enjoying my ER delusion since Jan ā20. Curiosity got the better of me 60 days ago though, so I tried the ENO Ag Ethernet filter from Network Acoustics which lām sorry to say brings even greater sonic benefits.
ASR will really hate this passive device with no complicated explanations or White Paper to justify the expense.
My Uptone has been moved to System #2 where it is still doing whatever it does to enhance realistic music reproduction.

This is why I specifically stated computer engineer. Not all engineers are equal - we have wildly varying fields of expertise.
Now, getting back to your question, I can probably tell you in not the most scientific terms whatās up with jitter (since thatās what your basically asking). The only problem isā¦ itās not really applicable to Ethernet (not in the way you think). Youāre confounding buffered/packet based transmission (which is networking) with bitstream (which is USB audio, S/PDIF or I2C). Just like not all engineers are the same, not all digital transmissions are the same.
I am happy to go into detail about this if you want.
Back to the bigger picture, itās easy to measure if a device does a job properā¦ especially when the manufacturer says it improves a specific metric. You measure that particular metric before and after and if the difference would be there, youād be able to measure it. If someone gives you a ruler and says itās 12ā, someone can take another ruler (a certified one) and check on video. If itās not 12ā, thenā¦ itās not 12ā. I donāt need to use it in my home to valide that it is or it isnāt 12ā. Do you see the difference here? Someoneās measuring a claim about a ruler, while someone else is just using the ruler to draw straight lines thinking their lines are straighter because the ruler is 12ā. They refuse the first personās findings because they tested the ruler and the lines come out straighter.

Thanks and spot on. But even when evidence punches some audiophiles in the face, snake oil sellers will keep thriving. Itās ridiculous. But hey

There should be no offence in this discussion at all.
Somebody will continue with eR to purely enjoy listening a music
and
Somebody will continue to purely enjoy reading measurements
Win -Win for All of Us.

Ah yes. It it only were that simple. Enjoying music means you enjoy āthe musicā and not fret about minute details that require absolute critical listening or else you miss them. Saying this because in the audiophile world ādramaticā started to mean ābarely noticeableā awhile back.
Someone asked above why do people like to rain on othersā parades and tell them how to spend their money. I feel thatās missing the point. Oneās free to spend his/her hard earned cash the way they see fit. My problem in particular is when they start advertising their subjective experience as absolute despite tangible scientific evidence to the contrary. People without technical knowledge in the computer networking field will read this as true, due to many peopleās testimonial towards this. Itās a bloody dangerous snowball effect. Sure, you have 30day money back (if youāre in the US I assume)ā¦ but for some itās just as Mulder used to say: āI want to believeā

Make no mistake, there is no change in the soundwaves reaching your ears. Its your brain interpreting all inputs (not just sound) and telling you its better. You put your money in it, someone told you its better, it looks nice etc. Sometimes your just concentrating more trying to hear differences and focusing on parts of the sound that hey magically seem better.
There is a whole field of psychoacoustics on this. A proper blind test will be enlightening.
The guy who has been doing this for years, has āexperienceā, tells you you cant hear properly or your system is not resolving - run away!
I have a buddy who makes cables and has made a fortune from these guysā¦

These guysā¦ which guys? Are you saying your buddy was making fake cables charging a fortune that did nothing, or all cables in general do nothing?
Does your buddy have a website on his cables? Or was he just duping family and friends through word of mouth, making a fortune in the process? Very interesting life story of yours.

Recently I have been decorating a utility room we had built and my attention to inconsequential detail has been brought to the fore of my mind along with the analogy of Ethernet switches, uber exotic cables and mains conditioners etc.
I am so close to the work, I could spend a lifetime touching it up and fiddling about, when actually I am completely out of touch with reality. Step back, It looks greatā¦
Once the room is fitted out, we will just walk in to use it with out even noticing a paint ripple here or a small plaster bulge there. Wether the paint colour (spelt correctly) saturation is greater on this wall or that, yet my focus been drawn to it for now.
Itās time for me to let it go and enjoy the fact the room is built and we can appreciate the function it allows.
For for Uber critical listeners to their already amazing Hi Fi systems, I would suggest the same 
Just a few thoughts as I wait for the paint to dry ā¦
