Thread: Network Acoustics Eno Streaming System

Next level in sound quality, a passive network filter

Better then the audio network switches known so far. Think I will sell my almost brand new Bonn Linns for this one. A step forward in network streaming. Anyone tested this filter already?

Hans did a thorough review, but personally, I'm not a fan of putting anything with chokes, coils, or inductors into a digital signal path.

Stephen,

Why would you focus on chokes and filters in this device as things you don’t like? There are dozens of things in everyone of our pieces of equipment. Who cares as long as the SQ gets better?

I hope to see more of these devices make it into the wild so we hear more reviews. While I think Hans B is a straight shooter, I would like to read more reviews from others with differing systems. They are pricey.

I have had the Acoustic Networks ENO ag bundle for about a week and its has made a worthwhile improvement to my sound. More density, less electronic glaze, better tonality and detail. Easy to hear. I first swapped the in Acoustic Network cable and that made a noticeable difference without the filter, and then I added the ENO filter. The sound has fleshed out even more, with very nice harmonic improvement. So you can count me in the yes column. I also own an ethernet regen (about 6 months). I think it's a very good product too. It improved PRAT, imaging and texture. I saw Han's you tube review so I have only used the ENO on the 'A" side of ER. That seems to be a good combo so far. I have not tried the ENO on 'B" side yet which Hans suggested was subtractive. I have no opinion on that point. FYI - setup is Orbi Satellite and one meter runs between ER, Nucleus+ and Rossini DAC, transparent ethernet is the other cable, (and LPS's on Satellite, Nucleus and ER). I was so impressed with the Acoustic Networks ag cable that I have two more 1 meter runs coming.

Hi Craig,
You raise some relevant points. Certainly we have chokes, coils, and inductors in our various components, notably choke filters in the power supplies of various amps, etc., and certainly, the inductors in crossovers in speakers.

But, I'm not a fan of them in power distributors or as "RF or EMI filters" for digital interfaces.

Agreed markramler. Alan Sircom has a very favorable review of the ENOag in the current issue of hi-fi+. He says "...ENO is one of the best things you can do to your audio system if you are streaming..."
I am interested in experimenting with switches too, I had not heard of the EdisCreation as an option. I will be interested to know what you think of it.

Yes exactly right. I ideally starting with a switch and the ENO ag bundle is a short 1.5 meter run directly to your source (dac or streamer).

I also have the ER and only use the A side into the ENO which connects directly to my DAC. The A side is superior to just using my Pakedge switch alone. I am using a Keyes P8 to power the ER. I found the B side changed the tonal balance somewhat, over emphasizing mids and upper bass and limiting upper range and deep lower bass. I ordered the EdisCreation Silent OCXO switch and will experiment with that switch and the ER.

Mark, when you say "Keyes P8" are you referring to the "Keces" power supplies? I have a Keces P3 that supports powering two devices independently and have been meaning to try it for powering my ER.

Yeah, those Keces power supplies are great. I use mine for my SOtM SMS-200 UltraNeo network bridge with a Ghent Gotham DC cable.

Yeah, those Gotham cables from Ghent are the best DC cables I've used, they won't pass leakage current. Actually, I need to order one with a 2.5mm ID DC barrel plug; the one I'm using for my ER is 2.1mm and it won't fit in the Keces; I'd like to try using the Keces for it, as you have.

Cheers.

BTW, just for edification of the gang, the Eno is an RF filter for Ethernet cables; if you are using a run of optical in your system, e.g. with a Gigafoil or Optical Module or ER with SFP/optical transceiver, you won't need it. It's function is to mitigate RF that can pass in copper Ethernet.

And, as the Eno costs about $1435, you can put together an optical solution for quite a bit less money than buying an Eno.

Cheers.

Puma - not trying to be difficult but you seem very against the Eno? Have you tried? Ive always admired your posts as you seem to have quite an open mind. But on this product it doesn't seem to be the case.

Based on this thread i bought one last week. It was delivered yesterday and i have to be honest, straight out of the box it made a difference and sounded better to my ears.... and my digital system is quite good and quite tweaked .....

I'm not against it at all. What it does is prevent passage of a noise factor that has an audible impact. It's just that there are other ways to accomplish exactly the same thing it is doing; stopping the passage of RF on copper Ethernet. Less expensive ways. These less expensive ways also don't allow the passage of high-source leakage impedance current to pass, as well, which the Eno does not mitigate.

If you're happy with yours, that's great. My perspective is you don't need to spend 1400 bucks to obtain the benefit it provides.

Don't know where "1400 bucks" is coming from. ENO is about 800 USD Products – Network Acoustics and doesn't require power. By the time one adds Keces or simiiar, plus maybe an aftermarket PC, to a Gigafoil or similar, one is at $800 or more.

I was referencing the €1183 price provided by Hans Beekhuizen on his channel, which includes VAT. Link here:

I just wanted to point out that RJ 45 sockets in Ethernet devices such as routers and switches have isolating transformers at their inputs and outputs, which are made from coils of wire, and some more advanced switches have chokes, or inductors. So you can’t get away from them.
