Stack Audio-SmoothLAN Network Filter- WOW!


I just received this item that I purchased from Stack Audio after being impressed with the AUVA 100 Speaker footers.

For any of the Audio Streamers out there, my initial comment as to this item: The SmoothLAN Network Filter is WOW!

From first plug in, the soundstage deepened and widened immensely. How the heck this occurs is nothing short of amazing. I have tried many of the major brand ethernet filters, and some of them, maybe, did something. But not enough to keep them. I either sent them back or sold them. I did however keep an iFi Silencer unit.

My digital streaming consists of an EtherRegen sending out the signal via Fiber to my Lumin X1. I have the Stack Audio device going into the EtherRegen from the Modem.

And, since I have my Apple TV coming out of the EtherRegen it will be interesting to see if the Video improves.

@maxwave Sorry: no, I don’t. Suggest you get in touch with the guys at Uptone directly. They are very responsive.

I think the change to the EthereRegen 2 is because some of the original parts that were used in the original EtherRegen are no longer available.

Not sure if this means it will sound better.

ozzy

What you guys said about the ENO having reduced dynamics is exactly what I would expect having seen a picture if it’s internals - it just has each wire pair wrapped around a potted ferrite ring.

My experience with testing ferrite rings (for signal and power) is they clean up the high frequency noise but reduce transient speed and dynamic impact. They give but take away more. I don’t like them.

With all due respect, what audible effect ferrites have in an analog cable (signal or power) would not necessarily be consistent with how they may work with digital cables. They would still reduce high frequency noise but how that may impact the resultant sonics could be entirely different. Just something to keep in mind.

@ozzy

On their web site .   : 1000mbps  capability on both side , 2nd SFP cage on side B , etc .

 

Therefore we now expect first shipment of EtherREGEN Gen2 will not take place until September 2024.

If , 100 mbps is the best for audio , I hope UpTone Audio will not take the 1000mbps road ....

The back to back Ethernet filters containing ferrites and caps are well established, so filtering on Ethernet lines is effective.

Conducted emissions are below 30MHz, above that frequency are your classic RF interference. I think you'd be unlucky for such a frequency to enter the copper bits of the Ethernet, the impedance is all wrong.

The case with the 20 screws can certainly keep the paths in, but won't radiate out. I wonder if plain Cat5 cable on the input 'will do' since screened Ethernet cables require a specific grounding scheme to be effective and ground loops are too common and difficult to solve. 

The supplied CAT7 would work since the shield in that cable connects directly to the SmoothLan filter, but beyond that to the source; maybe effective to remove the screen at the other end.

I've been using the DX ISO filters for some time cleaning up Ethernet, they work quite well and are half the price of the SmoothLan. Screened cables are not used in my network.

Still considering the SmoothLan, awaiting opinions from others.

The back to back Ethernet filters containing ferrites and caps are well established, so filtering on Ethernet lines is effective.

Well established to work by who? This it not IT networking, but audio. The ferrites not only will choke the signal by creating a magnetism effect, effecting not only the insulator and shield in the cable, but start to magnetise the connecting components. This is why no serious high end equipment uses ferrite chokes, only cheap stuff and the products by EE types who design by theory alone.

With all due respect, what audible effect ferrites have in an analog cable (signal or power) would not necessarily be consistent with how they may work with digital cables.

In the days of SDIF cables (and later USB), I noticed ferrite had the exact same effect as signal/power. And they are considered a digital signal, although possibly not the same type of digital signal as ethernet.

 

 

 

Thanks, Ozzy!  I have had the SmoothLan for a couple weeks and I believe different systems will see different results.  For me, it quieted the streamer so it now sounds smoother, more like an R2R.  I haven't noticed any difference in the soundstage, but the presentation seems less digital than before.

@agisthos, I apologise for the error in describing the back to back Ethernet filters.

The circuit of the Halo HFJ11-1G46E  Ethernet jack as found in the DEXE-ISO filter contains inductors, both air and iron core types, caps and resistors. They don't include ferrites.

The reason for the well established is how many of Ethernet RJ45 jacks contain noise suppression elements are available. 

Some interesting comments, perhaps starting to get off topic a bit though.

boxcarman,

I wish you could, or anyone else try a 2nd SmoothLan just to validate my own sanity. Contrary to what my wife says...

To me, adding the 2nd unit takes away all things that were digital sounding. Most impressive!

ozzy

Hey @ozzy, I have two SL's on the way. I'll give you an update once they're embedded in my system. 

@rms456 Sure, and I am not having a dig at the DXE-ISO filter, I am sure it does something positive. It probably is best to compare that one to the cheaper iFi iSilencer filter tho.

@ozzy if having 2 SmoothLAN's in series is only additive, with no negative effect, then I am sure Stack Audio will release a more powerful version of the SmoothLAN in the future. 

Well sometimes one is just cursed by the delivery Gods.  Order not originally shipped due to fulfillment system glitch (my order only), called after a week of no tracking and Josh apologized, item in black was then out of stock due to orders after mine being filled, back in stock several days later, Josh sent priority Fedex scheduled to arrive Friday 7/5, delayed a day in Memphis, further delay locally rescheduled for Monday 7/8.  All one can do is laugh, say “ ..it” happens and hope it is not a sign I should not have ordered the device.

campo007,

Please do so, so I can show the wife..

agisthos,

I sent an email to Josh about using 2 in tandem or perhaps create one super unit.

tksteingraber,

I hate it when that happens, I’ve been there too many times. Hang in there, hopefully it will be worth it.

ozzy

When waiting for a new audio toy I refresh the shipment tracking page like 50 times waiting for it to come.

The SmoothLAN was delayed from even shipping in the first place due to high demand. But it ended up being worth it, unlike many other tweaks that mostly are a let down.

Well miracles do happen…the SmoothLAN arrived after my post…Yeah! Well, right out of the box this was an “Oh My” moment. Everything improved on my modest system. The deep piano and guitar strings it’s as if you can feel the resonance and vibration. Separation of instruments clearer, improved 3D depth and bass just to mention the main takeaway. This is another winner recommended by @ozzy 👍👍. Thanks. Well worth the wait!

My hookup is Mesh Router-ethernet cable-FMC-optical cable-FMC-ethernet cable-smoothLAN-SmoothLAN ethernet cable- Bricasti Network Streamer. Etheregan with ext. clock due on Monday to replace second FMC in the chain.

tksteingraber,

Congratulations! You never know about delivery these days. Give it a couple of days to break in. I think it improves further.

ozzy

Having tried so many filters over the years I think it's worth mentioning the evolution is exciting to see. The ENO was actually the very first generation and some kind of pioneer braking the barrier for further generations. iFi, SN and many more have tried to come up with their approaches. So a lot has happened over the years and the new ENO2 including many findings that went into the Muon Pro will be quite a game changer from what I heard. So for those deciding about where to go next think that should be on the list to try.

And if someone is looking for an EtherRegen, also with a Farad Super3, Level 2 DC cable with Furutech and SR Purple upgrades - I got one for sale :)

@jmfinney, I know it’s a unfair comparison, but as you’re the only person I’ve seen so far who’s used both a full Muon Pro chain and a SmoothLAN, I’d like to understand where and to what degree the Muon surpasses the SmoothLAN.

Hey @ozzy

My SmoothLAN arrived and I did a first listening session.

My quick impressions: more punch, better instrument separation, and increased feeling that the music is outside the speakers.  In particular, pianos seem to have more 'weight', like going from a baby grand, to a 9' grand piano.  Same for drums.  Vocals are generally cleaner, more articulate.

The interesting thing is, the SL doesn't seem to hype/tilt the frequency response of my system; it neither adds/subtracts/shifts the balance...it just seems to make the music feel more 'full'.  More 'in the room'.  Very enjoyable.

I'm waiting for a second ethernet switch, so I can separate my computer network from my audio rig, and once that's in place, I'll give the SL a run-in period.

Looking forward to more listening.  The SmoothLAN is definitely a solid improvement to my enjoyment of my system.  Again, many thanks!

Best, JAMES.

 

I am waiting on my second filter.  The one nice thing about this filter is that it does not favor any part of the frequency spectrum.  Really a noticeable impact on adding space, tonal density and impact.

jimboman, jaymark,

Congratulations! Pretty good add on device for not too much crazy money!

I am really interested in your take once you insert the 2nd one into your system.

ozzy

Just a quick question. My SmoothLan will be delivery in the next day or so.

Where in your signal path do you have the SmoothLan? Before or after your switcher? 

I apologise if this question has already been asked. 

I am using mine after my EtherRegen switch…🤪🤣.  Josh recommended to start by using it right before your streamer after any switch but to try it in different locations to see what sounds best. 

Very Good Point. You and Josh are right!

I am using the Fiber optic cable out from my EtherRegen to my Lumin X1 that is why I use the SmoothLan before the EtherRegen. But without that scenario, yes, use the SmoothLan on the ethernet cable before the input to the source.

ozzy

I have one on order. Will be piggy backed with an EtherRegen( Farad super3 etc). 
Love the fact that it’s passive   My bud ordered one also so we can check out what 2 in a system brings. 

Thanks. I am now leaning towards having 2 in line may be reducing the "air" a bit. So, I look forward to other opinions.

ozzy

I received two units the other day. Installed one after my switch and before my Gustard R26. Just like everyone here, i can report the same effects. More separation of the instruments, slightly more micro details and dynamics.

After @ozzy ’s last comment i’ll try installing the 2nd SL before my switches, rather than piggybacking. Let’s see what that does.

Thanks for that link. Using 2 SmoothLan's

Since I am using Fiber optic cable out from the EtherRegen directly into my Lumin X1, my connections are different. I have tried running 2 SmoothLan back-to-back out of my modem into the EtherRegen with the Fiber optic cable out to the Lumin X1. Even though there is additional improvement sonically, I think 2 of them is reducing the image air.

I also have an ethernet cable out from the EtherRegen that is running to my Apple TV, so, I placed the 2nd SmoothLan before that Apple TV.

I think with this connection I am getting more additional "digititis" removed and it is improving the picture quality and... there also seems to an improvement further in my audio streaming sound.

But I’m not sure how this is possible yet. Any ideas?

ozzy

The You tube fella has his set into the dirty side of the EtherRegen. He tried it the other way and liked this way better. Contrary to what Stack recommends. Guess I can try it both ways when it shows up. 

So i placed the 2nd SL from the wall socket, then it connects to my switches (yes plural). Then out of the switches into another SL, then into the Gustard R26. 

When i added the one from wall as the 2nd one, i noticed a difference, but not as much as when i installed the first one. 

After several days of listening and testing the SL in front of my EtherRegen switch and after my ER switch I definitely prefer it installed after the ER right before my network streamer.  It sounder veiled, less detailed and less dynamic installed in front of the ER.  The SL has found its home.  Really does improve the SQ.

The SmoothLan is AWSOME! Now my digital music sounds like analogue 😀  So  I ordered StackAudio´s AUVA´s also. And this also is better than whatever I put under my speakers before. So my GAIA III´s are sold now. The AUVA (50´s) makes every small detail come through, the depth and the speed of the tracks is really addictive to say the least. The combination of the SmoothLAN and the AUVA´s is not to be missed. Never ever will I use the 30 day money back guarantee.

Thank you knockknock12, it really is a very important add on. And the price of admission is not too steep. 

There seems to be many from the USA buying them. Having them in stock now seems to be the only problem because of the demand.

I probably should be getting a commission! LOL.

ozzy

Ozzy 

The link about two SL  was sent to me by a friend of mine   : @captainsteve.

He ordered one SL after reading your thread

Yes , you deserve a commission 😉

maxwave,

I am having a problem finding that video again. That link seems to be a dead end.

Can you provide another link?

ozzy

@ozzy

I have no issue , watching the video

I ´´ underline ´´the adress  as if I wanted to copy it ; and instead , I click on ´´ open in Youtube ´´

Been playing with the Smooth Lan for a couple of hours. It’s early but I think I like better before the EtherRegen. I also get the benefit to an 85” Sony in that configuration

I am hearing an improvement in instrument layering front to back. Strings on Stand up bass with more definition. Melody Gardot sounds even more lovely. Bass on Blue Tofu’s “ A battle between”is impressive thru the swarm system.

Nice little 2-3 percent bump but they all add up.

 

Didn’t think there would be much break in,but after 24 hrs I am really liking what I am hearing. Very well rounded improvement 

I received a Mail from Uptone Audio

The EtherRegen second generation will be availlable  early 2025 .

 

tksteingraber

I'm not sure anymore which way is before or after the EtherRegen. My set up has the etherenet cable going into the EtherRegen and then I am using the fiber optic out from the other side of the EthereRegen to my Lumin X1.

For my arrangement, I definitely prefer the SmoothLan going into the EtherRegen.

ozzy

maxwave,

From my understanding the EtherRegen production was stopped due to the inability to get parts for that design.

So, I wonder if the EtherRegen 2 version will be an actual improvement in sound or just different parts?

benzman,

I know I thought it sounded even better the next day too.
