“Ones and zeros are just ones and zeros innit?” challenge objectivist Plebs, stage left in a Mockney styley
Who knew there was either a need or a market for an audiophile network switch? Until very recently such an idea would be in the realms of fantasy but there is now a burgeoning market as streaming becomes the norm for high quality audio. Your old scribe last investigated any kind of switch back in 2008 when questioning the audibility of selector switches and reviewing an audiophile selector switch from DACT.
“What is an audiophile network switch?” enquire Plebs, stage left
It is a misleading term outside of the context of ethernet LAN's. The best summary was offered by the designer of the Reiki Audio Superswitch, that it is fundamentally a galvanic isolator. Your old scribe recalls the potentially floating ground of transformer coupled balanced analogue connections. And like those transformer coupled balanced analogue connections, rejection of noise and interference are the big advantages.
The key to understanding the technology is that it is entirely passive in the signal domain (despite being powered). In the audio context the design intention is fundamentally different from other ethernet contexts.
Network switches are usually festooned with ports and LED's because their purpose
is to network. Thus the usual network switch looks like a junction box for ethernet
connections. Nigel Bell has rethought the network switch to suit audiophile use.
For this purpose, the typical 6 or 8 ports are superfluous, as are the LED's.
In the world of audio streaming, these superfluous ports are just holes in the screening.
The LED's simply double the number of these holes in the screening.
These are not tiny perforations to let flavour flood out (British tea bag slogan) but they are gaping orifices (fnarr fnarr - quoth gutter oriented Plebs) to let noise in.
While such features serve a purpose in the IT network world, from which primordial swamp such switches emerged,
in audio contexts the ports serve no purpose, but impede a switch from performing at is best.
At least they either allow ingress of external RFI (Radio Frequency Interference) and at worst the LED's generate additional RFI noise
themselves.
So Nigel Bell founded Reiki Audio Limited, a British startup company,
expressly to create and sell a range of high performance audio-optimised Superswitch Master and Servant ethernet switches.
Like many start-ups Reiki Audio Limited hope to disrupt the burgeoning market for audiophile network switches.
Is this a why-didn't-anyone-else-think-of-this? moment...?
“Or what snake oil is this?” challenge Plebs Chorus, stage left,
Another brick in the wall of audiophile wire, magic crystals, smoke & mirrors?
This is another TNT-Audio exclusive first listen to a new product from a new company.
Your Old Scribe is a sceptical listener, neither wooed by marketing spiel nor
persuaded by freebies & advertising budgets. As yet to join the streaming community,
your Old Scribe travelled one beautiful Summer day to the stunning landscape of
the
Lake district to visit designer Nigel Bell in his
modernist lair. Perhaps nominative determinism led Mr Bell's determination
to break new ground in communications and audiophilia,
Bell Labs having been a pioneering force behind the
invention of stereo and of signal transmission. The two operations share a tendency to
limit outsourcing to local manufacturers, eschewing the low-cost labour global markets.
Hence, the Reiki Superswitch range is designed, engineered and hand-assembled
in the UK The sleek 3mm milled aluminium case, the presentation box, the packing cases
and even the recycled foam enclosures are UK sourced.
Two factors led to this commercial decision. The UK is blessed with a huge number of
small specialist manufacturers. From the Little Mesters&apos workshops to the
SME's (Small & Medium Enterprises, not the pickup arm manufacturer
Scale Model Engineering) of light industry that survived the slaughter of the 70s
& 80s. In 2023 established custom & practice has been to outsource
manufacturing to countries of questionable worker welfare but if a new company wishes to
disrupt the market, this can apply to every aspect of the business.
The local supply chain has benefits in quality control too. Nigel could see and touch the
every part (including the packaging) before committing to manufacture. Reiki
Audioalso appreciated faster comms by dealing more locally. Smaller manufacturers
work in smaller batches so if Reiki Audio grow as planned, the onus is on their
suppliers to keep up. This does mean customers may have to forego the instant
gratification of the 21st century. From the trend for artisan everything, from bakery to
bespoke training shoes (sneakers in transatlantic English) we might infer that despite
austerity, there are customers for whom all good things come to those who wait with
apologies to Violet Fane.
The Reiki Audio Superswitch is an almost obsessive pursuit of noise exclusion.
The Superswitch Master is dual-shielded by its 3mm aluminium case backed by a
copper lining. The Master is for before and close to the streamer. To minimise post
Superswitch pollution, the Master should be as close as possible to the
streamer, hence comes packed with a 0.5m ethernet CAT6 cable and the1m is a backup for those not blessed with such proximity.
“Why not The Mistress to provoke some difficult to explain
browser searches?” ask the more mischievous Plebs, stage left.
The aesthetically identical Superswitch Servant, while a high performance network
switch in its own right, is primarily intended to be installed post-router to separate the audio
network from non-audio devices like computers, printers & TV screening. There is a
hierarchy of options. Both the Superswitch Masters and the Servants are available in
three versions:
Thus customers have a clear upgrade path from £649 Standard to full
£2999 Pro bundle with two linear power supplies, one each for
Master and Servant.
All this attention to detail will amount to nought if this makes no difference.
Nigel was good enough to refrain from any suggestion of what differences there might be.
Obviously past experience of reducing RF interference and minimising ground loops will set up some kind of a priori expectation in listeners.
Your Old Scribe listened to some familiar material to become accustomed to
Nigel's system. Your Old Scribe asked Nigel to cue up Pink
Floyd's Animals as a familiar go to test of system set up and resolution.
Even without the Reiki Superswitch in place, Nigel's system is sufficiently
revealing to notice that this was the 2018 remix within a few seconds.
With the Reiki Audio Superswitch in place, two things are immediately obvious.
The soundstage becomes deeper and more 3 dimensional. This is a typical phenomenon
expected with improved high frequency resolution, so could be an artefact of
confirmation
bias. It soon becomes sufficiently obvious that the difference is consistent to the extent that
it would probably be noticeable in a double blind test.
The second difference is the decay of notes and percussion. It becomes easier to
distinguish the natural decay of notes from the subsequent swell of ambience. The
phenomenon is similar to the difference between Red Book CD and HDCD, the briefly
available back compatible higher resolution CD format. We only had time for Pink
Floydand Lhasa de Sela's from the 1997 album La Llorana,
a spectacular Latin foray, especially revealing of percussion.
The track El Desierto was another example of the difference between the switchless configuration being
obvious from the Reiki Audio Superswitch Master set up.
We were listening to the Master and Servant from the middle of the range
Plus configuration, so it is not possible to comment on the Standard or
PRO versions.
In terms of cost vs benefit, the Plus is the kind of wedge that folk will happily
pay for an interconnect based on a favourable review. The sound quality gain is equivalent
to a better DAC up one level in a manufacturer's range.
Superswitch Masters and Servants are available in three versions: standard with a stock low noise SMPS;
The Plus version comes bundled with an iFi iPower PSU;
The PRO models have a custom-designed linear PSU.
Prices range from £649 for a standard Superswitch Servant to £2999 for a Master & Servant PRO bundle (2 switches and 2 linear PSUs).

The Reiki Audio Superswitch Pro bundle compares to the direct rival Innuos PhoenixNET at almost £3k.
If streaming is now your primary source, value consideration will be different from those
who use streaming for background. You pay your money and you make your choice.
Reiki Audio hope to shake up the infant but growing audiophile network switch market with
the various options of Master Superswitch and Servant Superswitch.
These first production units are Artisan audiophile products of fine fit and finish, made in small batches.
The high quality audio market is changing fast and Reiki Audio are confident that any customers who do have
to wait a few weeks will find the wait was well worth it.
First impressions are favourable so a more in-depth review will be appropriate in due course.
Nigel Bell is somewhat design obsessed and these products show it.
The designer's IT background ensures that the Reiki Audio Superswitch does what it promises.
This product is also evidence that improving the signal path for ones and noughts can be an effective upgrade.
