The new English Electric EE1 Plus Ethernet Noise Isolator is designed to eliminate noise and interference at the network level, according to the manufacturer.
In most cases, the English Electric EE1 Plus Ethernet Noise Isolator serves as the final touch for a high-end hi-fi setup. The device aims to filter out noise that may be present in your wired (home) network, in a completely passive manner—meaning it requires no external power source. You simply place the filter between the Ethernet cable from your router or switch and your audio device. The filter’s housing is made of aluminum, and it comes with two decoupling isolation feet.
Relatively speaking, the EE1 Plus is not exactly cheap, priced at £600. However, as mentioned, it could be the final step in achieving an “ultimate” high-end system. Additionally, it may come in handy if you’re struggling with persistent noise that cannot be eliminated by other means, such as upgrading to higher-quality Ethernet cables.
These filters are much too expensive.
The few parts inside are mostly not more than
50 -100€ worth. The rest is only marketing.

Wow… again same way of thinking: “This is not worth it… the parts are only…”. Please. Start your own business and try to make it cheaper and still earn a decent way of living. I challenge you.
I am surprised that you are reacting so extremely.
Did I perhaps hit the nail on the head with my statement?
For more than 50 years, I have been involved with high-quality hi-fi equipment. Starting in 1975, I financed my studies by working as a high-end consultant in a very good hi-fi studio. Even back then, it was noticeable that under the label “high-end,” especially in the accessories sector, a lot of money was being made, while the ratio between performance and value was steadily declining. Today, so-called high-end accessories are sold at completely inflated prices, often failing to deliver what they promise. That is what I wanted to express with my criticism.
I understand that Alpha Audio must remain reserved when it comes to pricing policies of manufacturers, as cooperation with hi-fi companies is essential for Alpha Audio’s continued existence. As a user, however, I do not have to impose such a restriction on myself!
Best regards,
Michael
Michael, which similar type of filters have you tried?
I ask since my experience is that they sometimes offer good value for money, compared to spending the same money on a streamer or DAC to combat the same noise.
£600 might sound steep, but it depends on the level of impact it does.
Hello Tobias,
I don’t deny that these filters can have an effect — depending on the system and HiFi setup, more or less. However, I’ve often found that the advertising claims are exaggerated. I’ve tried several of these filters (iFi LAN iSilencer, iFi LAN iPurifier Pro, Baaske Medical MI 2005, English Electric EE 1, Stack Audio SmoothLAN), with the last two performing the best.
Currently, I’m using the ethernet-sound.com LAN Isolator V1 — essentially a DIY product — which, at least in my setup, completely outshines all of the above-mentioned products in terms of sound quality, and at a fraction of the price.
I’m using the Furutech LAN-8 NCF Plus network cable, the Innuos Pulse, and the T+A DAC 200 as the DAC.
Hi Michael,
The ethernet-sound.com LAN Isolator V1 how/where cac I get one?
Hello Ed,
go to ethernet-sound.com and ask,if somebody of the members would like to sell one.
The price is around € 60,-
And I bought an even more expensive filter… For the record, my system is far from ‘ultimate’ 🙂
What filter are you using?

That is a nice filter. Hans Beekhuijzen uses one as well, I think.
Could be the final step in achieving an “ultimate” high-end system!! Big words!! I thought i was finished with building a network and now this comes along. Just spoke to my local dealer and he one for demo. Can’t wait to try it.
Hope to hear from your experiences.
I have a mass-produced medical isolator and even these small things are not cheap (> € 100).
At some point in the network it degraded sound quality a tiny bit, but now I use it to isolate my Roon Nucleus One from the switch with great result. An audio designed isolator like the EE would probably work even better.
My conclusion is that it works really well on cheap to midrange ethernet cables, and hardly if any noticeable effect on more expensive cables. It made absolutely no difference in my system. Still fun to test. 🙂
