Back at The Bristol Hi-Fi Show 2020 in February, Chord Company announced it was relaunching English Electric* to front its audio electronics business. It debuted the first English Electric product, the 8Switch hi-fi grade network switch – which, three months later, is now on sale.
The eight-port 8Switch has been specifically designed to act as a filter for streamed audio to remove unwanted noise and thus preserve music quality. Supposedly, the 8Switch lowers jitter by up to 90 per cent.
The 8Switch, which features eight 100/1000 Base-T gigabit Ethernet ports, is driven by a customised crystal oscillator that English Electric says allows for a more stable transmission of music data.
It uses a power supply and clock circuit that each have two electrical noise-isolation circuits for stabling network signals, as well as EMI (Electromagnetic Interference) absorber for further reducing noise from the digital circuit.
That's all housed in an aluminium enclosure to protect it from acoustic and electrical noise, with damped feet also doing their bit to reduce the effects of unwanted mechanical vibration. English Electric’s engineers even set out to improve the power signal by using a high-quality adapter.
The English Electric 8Switch, which launches alongside a dedicated English Electric website (opens in new tab), costs £450 and includes a 0.75m Chord Company C-Stream (opens in new tab) Ethernet cable worth £40.
*Founded in 1986, English Electric (as it became known from 1918) grew into a manufacturer of electrical equipment and machinery, specialising in motors, transformers, railway locomotives and traction equipment, before expanding into consumer electronics, computers and aviation years later. After several mergers, the name was lost in the late '60s – only to be reborn in the audio sector here in 2020, over 50 years later!

Let's go through the process of getting some music from one device to another over a network. The sound is digitised into whatever format one chooses - and here there is definite opportunity to lose or gain quality. But once it is digitised the parcelling up and unpacking of the digital stream into ethernet IP packets is carried out by the devices at either end. They are in control of how accurately or otherwise this process is performed and this is very well understood science. If this did not work correctly then we would not be able to use ethernet as a transport medium for anything as files would be corrupted right left and centre. That doesn't happen! There is error correction and error detection built in to the ethernet standard.
The switch sits in the middle of all the kit and has a minimal contribution to make, assuming it is doing its job correctly. It just receives packets and passes them on, and the bandwidth of any switch is generally vastly greater than is necessary in a home environment.
Where is the evidence that this ridiculously expensive and vastly over-engineered device makes any measurable difference at all to the sound when compared A to B?
Come on, What HiFi - where is your critical and sceptical journalistic approach when it's needed? Don't just swallow the hype - test the assertions! That's what journalism is all about. If you don't do this then companies can offer anything at any price and make mugs out of us all.
If you can measure a difference then I am prepared to eat my words, but I struggle to understand how it would be possible.
One of the main "advantages" of this device appears to be reduced jitter but, surely any decent DAC (or DAC equipped streamer, amp etc) will have it's own clock and kill jitter itself.
