New Network Acoustics eno2 system

Found the installation instructions chocked full of great tips! https://www.emosystems.com/wp-content/uploads/Datasheet_EN-85e.pdf
They do a wide range of units for different situations, mostly aimed at the medical market, but also the general computing market, train systems and audio. Many different specs, speed from 100mbps to 10gbps.

I think these also units reduce RFI because the LAN transformers only operate at the data signal frequency band, any other frequencies can't get through.
The unit recommended for audio is this one.
Specifications here

The one you picked out makes sense because you can never get a reliable wireless signal in a hospital. Much medical equipment is mobile or on wheels and the last thing you need to do it damage the RJ45 socket by accidentally moving the unit whilst plugged in, hence an auto-release LAN isolator.
 
I get your point. Problem is, a network has many variables on how its set up. And having the foundational infrastructure correct is important. It has a profound impact as you get closer to your streamer. Most ethernet devices plug in between you playback device and the ethernet jack in you room. So people like to clarify you should set everything up corectly before that jack in the wall. Then test the device in hand. Most serious audiophiles are going to utilize high quality routers, switches, power supplies and vibration control before the ethernet jack gets to the room. If someone were to give there opinion of what the Eno2 does without addressing the foundation of their data stream, then their perceptions don't have merrit to someone who has spent the time and money to do it right.
Agree. Who reason for my original post. The likely worst supply would be in a room in a hotel at an audio show.

No one needs to tell you that electrical systems have to be designed as a system, not sections in isolation. Same with ethernet, although it is vastly simpler in most domestic settings. An RFI filter makes no sense for optical cabled systems.

I don't even have a wall jack to contend with. I have one central switch for the house, the relevant devices are connected to that with 1m CAT6a (modem, Mac Mini hosting Roon Server and HQ Player, SATA network library). A fibre cable runs from that to the audio system through wall conduits and out a cable plate without any break. It then goes into a media converter (battery powered).

Hi Tom,

Thanks for your reply and good afternoon/evening I guess to you. It's evening here in London but I guess there's a good chance you're in the US.

I appreciate and agreed with the majority of your reply. And FWIW I'm not arguing for stronger/tougher moderation. These forums work best when people self moderate in my experience.

My annoyance (and perhaps my post was a little punchy) was that one person posted the advert for the Eno2. Kudos to that person so sharing the news and making people that might have otherwise missed it aware of the new product. But after that there is literally no discussion about the Eno2 and instead people started banging on about audiophile routers and ISP providers. I'd be genuinely interested in reading about that. But on a thread about Audiophile routers. It's not thread drift when the thread literally doesn't discuss the stated topic.

I just bought a Tempus. It's fantastic. As are Network Acoustics. But the Tempus thread really didn't help with my decision because they haven't discussed the actual Tempus for like a year now. Hence my frustration at this thread.

I also own the Muon Pro which is likewise fantastic. But honestly it was Audiogon rather than this forum that drove that decision.

I understand I'm not winning any friends here but there's a difference between thread drift and free association just posting whatever is on your mind currently. I think that's what Facebook is for.

Meantime if anyone has actual experience with the Eno2 then it'd be great if they can share that.

Apologies for being a grumpy Scotsman but such is life.

Cheers,
Alan
Here in London it's now 1:33 am.

Perhaps you could share a description of your data network from the street onwards (do you have fibre or copper ethernet?) and where you put the NA devices that made a difference.

As I'm sure you are aware, but maybe not those in Texas, here in London and the UK generally we have a mix of old BT copper networks being replaced by fibre, conversion now about 50% complete, and competing fibre networks, most installed over the last 20 years. I'm signed up with fibre. It makes a big difference.

Running the data through more devices also has an effect. The only one I can measure is speed. Ubiquiti networks are superb, but in my house it almost halves the speed. This is not critical, it's plenty fast enough, but who knows what various devices do.

I was actually local to EMO's US distributor (in N Texas) for several years. They told me that the en-85e is actually best suited to audio use. I tried the en-70HD and a few others (en-30, etc) and found that the en-85e was by far the best. Electrically, it is also the most efficient.

I have several en-85e's and they work very well where full gigabit speed is needed. Not as well as a Stack Audio SmoothLAN, but better than a iFi LAN iPurifier (non-pro).

I think the Stack and EE-1 from English Electric (Chord) are fine devices.

I haven't used the EE-1 in my systems, but I've heard one in a buddy's and they work really well.

The SmoothLAN has offered superb performance in my system. Besting some much more expensive Ethernet filters. The only downside for the SmoothLAN is that it is restricted to 10/100. Fine for an endpoint, but I use an EMO EN-85e (full gigabit) for my Nucleus Titan because I don't care to restrict my server to 10/100.

If they made a Gigabit version that sounded just as good, I would buy at least one tomorrow.

You really are not restricting it as your server only uses so much bandwidth. Work great in my system I left the Roon platform long ago for Innuos.

for $175.00 I am going to give one a spin. They are just the next town over from me.

Yeah I spent a few years in McKinney. They are good folks and it's 100% worth the effort to try it out.

We were practically neighbors. Allen is great.

I changed jobs and was forced to move to Houston. Not ideal. But the job is great so far.

When I replaced a Shunyata Venom cable connecting a modified Meraki switch to my RPi4 streamer with the eno2 system two months ago, I worried that music became too relaxed, without enough of an edge. Now I’m used to what I initially thought was “polite”, realize that dynamics haven’t been compromised, and am happy with the sound…

The EMO EN-85e and EN-70HD are both gigabit capable, but the 85e has lower insertion loss.

I'm obliged to use Innuos and Roon, as I use Innuos Pulsar in HQ Player endpoint mode and the best control point is Roon. As Roon Server resides elsewhere on the network, it has no impact on sound quality. I was using an Innuos Zen Mk3 before with Roon Core onboard and using Innuos Sense instead of Roon was better because it uses dramatically less power and generates far less noise.

Innuos is really optimised when used in endpoint mode, whether running Sense, Roon or HQ Player. That's why they have two RJ45 ports so you can connect another Innuos device directly using an ethernet connection. I did that for a while, Innuos Zen Mk3 to Pulsar in Sense endpoint mode. The Zen was at the other end of 40m of fibre cable. It is excellent but was overkill for me and I use HQ Player now anyway.

Okay so let’s get this thread back on track. I think the OP was talking about the ENO 2.

OK. It's an RFI filter. I don't understand the claim by NA that only half the channels in other devices are filtered. They all are.

This is the inside of the Delock filter, next to an EMO (impossible to crack open).
The Delock contains a $1 chip the has a transformer for each channel pair.

Some of these devices have been tested. The results are here. The $10 Delock does as well as $150 Pink Faun.

If you read the comments on the review thread, these filters are particularly effective when placed between a wifi extender or a computer. These can be very noisy devices.

If there is an RFI issue to solve, it's likely the connected devices and the streamer itself. Hence Innuos is popular because it is extremely low power and low noise, and well shielded inside, the Taiko Extreme shielding looks superb, second only to the Marantz SA10.

Besides the casework, not sure what NA adds to known technology.
I would like to use them on the mini PC server. I think they also work well on routers and switches. Have you also tested them on small electronic devices like these?

This tape costs $15 and is easy to apply, took me 10 minutes to line a switch. Several brands available on Amazon.

Any decent CAT cable has a copper braid shield, one of 2 or 3 layers, wrapping a cable in this stuff is totally overkill.

Exactly, and they aren't saying. As I understand it, the original Eno and Muon used the Networks Acoustic version of conventional LAN filter technology. The Muon Pro and Eno II contain that tech, but add something else.

Medical and life sciences equipment users have known this for a long time and companies, mainly in Germany, invented devices that galvanically isolate and voltage protect wired digital technology. Specifically, Intona did usb and EMO Systems did ethernet. It's cheap, effective and they are the world leaders. So excuse me for being sceptical . I'm often interested in new technology. I'm skeptical about such claims being old technology dressed up.

It's easy to see what these products do and test them. Archimago did a test of an Intona USB isolator here:
It works

I referred to ethernet isolators tested here:
They work. You can get them for $10 or $150 and they work just the same.

I just installed the EN-85e in my system and quite honestly I can not tell a difference between this unit and the Stack SmoothLan. Going t listen a bit and look at installing a second 85e in my modem/switch room across the house. May be selling a SmoothLan.
