Live Stream Switch Test - Paul Pang - NuPrime - English Electric - Cisco - SOtM 

Thank you for making such a great test.

From your recommendation, I bought the Netgear GS108 to replace the TP Link. I also added the ifi power supply. Finally I added Audioquest Cinnamon. Delighted with the result. A very nice difference allround

Interesting test. Thanks for making the test. Ansuz have some interesting switches. It would be fun to see what they can bring to the table.

Wow, even on laptop build-in speakers (ThinkPad T480s) I heard a difference when you plugged Paul Peng switch. Amazing!

Congratulations again, to all of you!!

I am more than happy to have both my Ferrum Hypsos's (had and still have the Farad Super3) instaled one on my DAC and one on the Melco Switch, both products are a no brainer.

power is everything! good power = good audio.

Great work and thanks for doing this test. Hearing is believing!

Finally had a chance to hear an LPS with my EE 8 switch tonight. Definitely improved the sound vs an iFi switching supply or the stock one. I am using a Nuprime 205 supply.

Обожаю эту аудиофилию! Love that audiophilllllia!

Interesting that one person was talking about hiss during James Taylor's piece. Um, yes, welcome to early analog multitrack, especially using no noise reduction during the recording. So, you ARE hearing what's there. Early noise reduction encoder/decoder in the studios, like Dolby A, wasn't all that great, so most of us didn't use it.

Great test guys, what is missing here is a Luxul av switch e.g Luxul ags-1016

sorry ik vroeg mij af weer deze dingen voor gebruik werden maar dat is inmiddels duidelijk nogmaals bedankt voor de reactie

It sounds (!) professional and "genuine".

it's a pity that you didn't uses in your test the SOTM with add-on sCLK-EX module with also and additional Master Clock connection that would have been a better comparison to the more expensive Pail Pang which also re-clocked the signal just like the Uptone EtherRegen and others

You could have borrowed my EtherRegen :) Any experience with that meanwhile or any idea / guestimate where it would end up in the test? For me the effect was very subtle, maybe a bit more relaxed sound but again, very subtle difference. Have it still on standard PSU, will upgrade some day.

Question. When you did this test, were you using power conditioning? I’m wondering if part of the change was noise being kicked back into a shared supply for the other components.

What kind of modem and router do you suggest, I have some strange intermittent noise coming from my speakers that is heard while listening its only in the high frequency range, sound like hissing and digital distortion cracking noises. It's not loud but it's there. Do you have any idea what it could be? Thanks

Fantastico...................!!!!!!!!!!!!!!!!!!!!!!!

Vanavond de test opnieuw bespeeld via de setup in de woonkamer. Wat gelijk opvalt als je van kale router naar tussenkomst met switch gaat, is het aangenamere geluidsbeeld dat ontstaat. Het klinkt "analoger" als ik dat zo kan omschrijven. Bij de cisco viel bij gebruik van de betere voeding, gelijk een strakkere laagweergave op. Zit nog in de test te luisteren, maar had nooit gedacht dat een switch en/of voeding nog zoveel kan verbeteren. Zonder switch klinkt echt niet lekker! Btw als het op power supply's aankomt, is er ook nog weer veel verschil onderling. Kort geleden een klein testje gedaan met 2 verschillende lineaire voedingen, en een standaard switching power supply. Als je een oscilloscoop aansluit ben je snel uit de droom, en wil je echt geen switching power supply meer! Zelfs tussen liniaire power supply's zie je verschil in ac rimpel over je dc spanning...

Hello gentlemen, which switch is better in your opinion Paul Pang single or NuPrime omnia sw 8. They will be powered by a linear power supply. Thank you for your help.

Alpha Audio -- Thank you so much for posting this information! It's very helpful! Has anyone compared using a LAN isolator, vs. a Network Switch? (Pink Faun LAN Isolator or iFi LAN iSilencer) I wonder how a LAN Isolator would compare to using a (non-audiophile) Network Switch -- such as the Netgear GS108E combined with a linear power supply? Any experiences with that?

Loopt er een weg langs het pand? Ik hoor in de achtergrond auto's voorbij rijden? :) De mics pakken alles op. Dank voor de test. Het heeft me overtuigd om niet al teveel geld te steken in een switch, maar wel te zorgen voor een betere power supply.

Hi Alpha. Did you mod the Meraki Switch afterwards?

In fact! If I only use the built-in SSD to listen the songs and tidal (Auralic Aries G2.1) , can I just to use wifi? Then no need audio grade switch / Fiberbox / hi-end lan cable....etc >>> (Does NAS only need these equipment?) Thx !!

What kind of Ethernet cables did you use, the red ones looks cool. Thanks

I've been using just a router! Then I watched this clip and learned alot. Just bought a secondhand nuprime sw8, is it worth buying an ifi ipower as a power supply upgrade or save up for an sbooster?? Fantastic demo. keep up the good work.

Net klaar met jullie video die duidelijk de verschillen laat horen tussen de verschillende switchen en voedingen, knap gedaan!! Nu gebruik ik zins kort een op een RPi gebaseerde Ian Canada streamer setup die mijn inziens de verschillen die hier naar boven komen gewoon onboard goed aanpakt doormiddel van een volledige galvanische scheiding van de RPi (inclusief zijn netwerk aansluiting) en batterij voedingen aan de schone kant, in de toekomst verwacht ik dan ook dat we streamers gaan krijgen waar dit soort toch wel prijzige oplossingen (als je het beste wilt) tot het verleden gaan behoren.

What kind of ethernet cables did you use?

Its crazy but I preferred the Meraki overall. I felt it has more holographic imaging and I wonder what a good ac power conditioner would do for the piano notes ( admittedly not the best).

I prefer the single Paul Pang with Hypsos for musicality with better bass articulation. I assume the quad was not with Hypsos power supply but with the pang supplied one? If so, would have been interesting to hear the hypsos and quad together

Apologise for going off Topic. I was just wondering is there a way to measure the noise floor 🤔 many thanks

Chaps, could I ask why did you not run a blind test, say out of 10?

Mooie en interessante test, mag ik vragen wat in detail jullie recording setup is in deze test?

i like Meraki MS220 with fiber

can Quad can be improved upon linear connection with SOTM supply?

do you think the paul pang switch is better than the melco s100?

I already bought the Paul Pang Quad, and if it sucks, I’m coming to Denmark to complain in person! 😂

which version of SOTM you used? 7

What do you currently recommend in the $500 and below price point? Been looking at the Gustard N18 or LHY SW6 or Netgear/Dlink with LHY LPS.

I tried to purchase a paul pang single switch as that set up with the hypsos power supply was my favourite from this demonstration but he no longer sells them and I couldn’t find one from a reliable source elsewhere so I decided to Play around with which of the eight ports on my ubiquiti basic switch my router, Nas box and switch were plugged into. I got this idea from seeing how Paul Pang seems to use specific ports. My apologies in advance to the flat earth society Tyre kickers Who may read this and say impossible it’s all in my head but I found every time I switched ports around the sound changed quite dramatically given what a small change this is. The good news is that a lot of the improvement in sound I was looking for I eventually got from aparticular combination of ports. I do have a fairly high resolution system but the differences were very obvious including a big difference in how the bass was reproduced. Much more grip and articulaion I also on another tack Rearranged my gear so that I could plug the router Nas box and switch into a totally separate power point which like my hi-fi PowerPoint is dedicated back to the switchboard and this also made a huge difference to the point where When I played the Ultravox track Mi-Sex Which has fairly deep bass the drivers on my right hand speaker were over driven by the signal which was much more articulate and detailed and controlled especially in the bass which was where I really was looking for improvement. I can only speculate that in their original mix down they panned the bass a bit to the right as the left-hand speaker has no issues and I have no issues another bass heavy tracks. My point to the open minded is you don’t need to spend money just try different things even just plugging things into different power points in different groupings. Thanks alpha audio again for this demonstration which inspired me Actually the only sunk cost when I think about it was years ago putting in dedicated power points each to their own individual switchboard trip switch using heavy cable which itself was a worthwhile upgrade

So I used to stream with internet over the powerline as I did not have a dedicated cable into the room I listen in. I have now implemented a direct connection using a switch from the wall socket in an adjoining room, and a second switch by the Hi-Fi. The joining cable is a home made Cat8 with Telegartner connections. I have yet to improve the actual shield as the switches at either end (Netgear GS108) are not themselves connected to ground (I will do this directly on each unit) I did not turn off the internet over mains just unplugged the CAT cable to my streamer I have yet to try improved power supplies for the switches. I expected to hear an improvement even in this form......but alas I preferred the original set up 😞 do ethernet cables need time to run in like other cables? Thoughts?

Goeie tip om de audio te scheiden van de rest van het netwerk. Zelf ben ik een stap verder gegaan en houd mijn Word-documenten op een apart netwerk tov mijn video's. Zeker als die hele lichte beelden hebben, zul je de documenten minder goed kunnen lezen. Jaaaa, data is data. Het gaat hier natuurlijk om de ruis. . . . . . . . 🤦‍♂️🤦‍♂️🤦‍♂️😂🙋‍♂️ Ik ben via via op deze review terechtgekomen: www.alpha-audio.nl/review/multitest-de-beste-switch-voor-streaming-audio/4/ Erg vermakelijk, maar er klopt natuurlijk niet veel van. "Data is data, maar het gaat om de ruis", wordt er gezegd. Maar ja, als je audio over een netwerk streamt is de audio zelf de data. Dat is alvast de grootste fundamentele denkfout. Stel dat dit waar zou zijn, dan zou mijn muziek beter klinken als ik het vanaf een netwerk afspeel dan vanaf de interne schijven. Beetje onwaarschijnlijk, is het niet? :) Dat beetje ruis, dat overigens absoluut meetbaar aanwezig is, zal een fatsoenlijke verbinding niet verstoren. Het heeft geen enkel effect op de dataoverdracht. Als het wel effect heeft dan uit dat zich effectief in dataloss. Hoewel je bij UDP dan gedropte pakketjes zal krijgen, zal bij TCP een pakketje alsnog verzonden worden wanneer het verloren is gegaan. Maar een gedropt pakketje zal ook bijvoorbeeld effect hebben op video. Het is onjuist om aan te nemen dat een betere swicht de bron verbetert. Het signaal komt in het ideale geval onveranderd aan, anders is er sprake van een verstoring. Verder is de luistertest niet goed uitgevoerd. Om enige vorm van bias te elimineren zal er altijd dubbelblind getest moeten worden. Echter is dat in dit geval niet eens nodig. Een simpele null-test zal uitwijzen dat er geen enkel verschil zal zijn. Ook is de gebruikte termologie totaal nutteloos. Er worden bijvoorbeeld hele subtiele oordelen aan gekoppeld. Omdat deze voor iedereen een andere betekenis hebben zijn ze totaal niet concreet. Ook worden er dingen geroepen die totaal de plank misslaan. Kom op joh, een andere switch zal geen effect hebben op een S-klank. WTF 😂 Dit is gewoon de hoeveelheid energie in het gebied rond, breed genomen, 3-8kHz. Met een simpele eq kun je dit versterken of verzwakken. Dit kun je meten en verifiëren met een simpele analyzer. Maar goed, als je concreet gaat meten zie je al gauw dat een andere netwerkswitch geen andere resultaten zal geven en dan wordt de marketing-bullshit onderuit gehaald :) Het blijft fascinerend dat mensen zich zo om de tuin laten leiden op het gebied van audio. Ik kan iedereen het boek the Audio Expert Second Edition van Ethan Winer aanraden. Wanneer je de kennis hieruit hebt opgedaan, is het vrij eenvoudig om door alle mythes zoals die over magische netwerkswitches in deze video heen te prikken.

Paul Pang his equipment is quite good although I had my server go back twice and the switch once. The service however is really bad. He won’t respond to emails even though I reached out 4 times now. The disk which broke in my music server was probably under warranty but as he never responds, the warranty is now gone.

Waar gebruik deze Switch voor

I think its funny how all say keep computer away from gear... Meanwhile all recording studios have computers in the mixing room lol .. enjoyed video

How to react when someone produces detailed measures that show there is 0 impact ? Is this placebo ?

I wouldn't be here if I hadn't plugged a $2000 power cord into my $12 ethernet switch and it doubled the sound quality

Was curious after seeing this video and so I tried something else..before my streamer was directly wired to the modem (Telenet, Belgium) and I used a Ifi Ipower x with this modem. I now power the modem again with the orginal power supply and used the Ifi for a Linksys network switch, so I go from my modem to the switch and then to my streamer. I was surprised by the difference 😳 everything sounds fuller...very strange. Maybe it is part placebo effect but now way I change it back as before 😅👍

This would be worthwhile if it were blind or double blind tested. So this is a fail guys.

Doesn't Meraki require a recurring license?

"D-link on the stock powersupply" meaning what ? Does the Cisco have a separate powersupply? And can you attach a D-link to it? And what is a D-link? It did made a distinctive difference for the better.

Waar zijn de metingen?

The SOtM will sound much better after staying on for 2 hours. not just a common design, have to warm up.

A switch will make no difference to the sound of audio. ! You need to do the test double blind. Some times change nothing, and people will still perceive a difference. The brain changes from listening to analyzing, and both a very different. Enjoy the videos even if the tests are flawed.

When streaming, the data isn't being sent just in time as it is played, instead, it is being sent in chunks of data that get queued up on the streaming device (clock and jitter from buffer to DAC is only related to streaming hardware). Unless the network connection is so bad that it can't keep the buffer full then there is no difference. If for some reason you are having issues then you can enable the QOS settings in your current network hardware...... After watching a bit further, it seems you think a better power supply is required. This doesn't make any sense as ethernet is a galvanically isolated connection. A side note, did you know that when reading data from CDs/HDDs/etc that a good chunk of the data is read wrong and algorithms recreate the bit perfect data to send. As the data gets sent through the network, it is constantly queued and buffered at each switch or end point including the streaming device and algorithms (error checking) can determine if the data is 100% or not.

I don't see any data. All your tests sound just like my computer speakers. Without objective data this is not a test. Why don't you run multiple blind A/B/X listening tests, I would like to see you statistically prove you can hear ANY differences between these switches and a generic switch. Without a way to eliminate placebo and bias effects, there's no way to show that these expensive products have any REAL effect other than to enrich their manufacturers and retailers.

literally didnt hear any difference on any of them. nice snakeoil
