Elevate Your Sound: Vera-Fi Audio’s Main Stream and SnubWay for the UK

Welcome to Vera-Fi Audio’s Main Stream and SnubWay – innovative AC line conditioners crafted to boost your audio experience. Designed for audiophiles and home entertainment lovers, these devices eliminate mains noise, delivering pure, high-quality sound. Whether you’re enjoying vinyl, streaming, or movies, they ensure clarity by filtering electrical interference. Tailored for the UK, each comes with a premium UK adapter plug for seamless compatibility.
Electrical noise from chargers, LED lights, and appliances often disrupts audio, adding hiss or dullness. The SnubWay targets noise from 10kHz to 2MHz, peaking at 400kHz-600kHz, where SMPS interference thrives. The Main Stream tackles RF noise from 10kHz to 20kHz, smoothing out hum and hash. Together, they create a cleaner, richer soundstage. Their parallel design offers flexible placement – use them in a power strip, conditioner, or wall outlet near your setup.
Encased in sleek aluminium with top-tier Viborg connectors, the SnubWay uses LRC filters, nano-graphite absorbers, and copper coils to “snub” noise. The Main Stream enhances detail and depth by reducing RF pulses. UK buyers get a reliable adapter plug, ensuring easy setup. Expect tighter bass, clearer treble, and stunning detail – all at a fraction of the cost of premium alternatives.
With over 110 years of expertise, these US-made filters bring professional-grade performance to the UK exclusively from Townshend. Upgrade your system today with Vera-Fi’s Main Stream and SnubWay – complete with a quality UK plug – and hear the difference for yourself. Great sound deserves perfection.

Why pick Main Stream?

Vera-Fi’s SnubWay and Main Stream offer premium audio enhancement at a fraction of the cost of expensive conditioners. While high-end units cost hundreds, these deliver top-tier noise reduction and sound quality. SnubWay tackles 10kHz-2MHz noise with LRC filters and copper coils, while Main Stream cuts RF interference at 10kHz-20kHz, rivalling pricier gear. Their flexible parallel design fits any setup, unlike bulky alternatives. With 110+ years of expertise and a UK adapter plug, they bring pro-grade results affordably. Upgrade smart, not expensively.
See the SnubWay Noise Defender in Action: Noise Floor Comparison Graph
Curious about the SnubWay Noise Defender’s impact? Our spectral analysis graph reveals its power in taming high-frequency noise for cleaner, clearer audio. Spanning 10 kHz to 2 MHz—the range where switch-mode power supplies (SMPS) like phone chargers and LED adapters wreak havoc—the graph compares your system’s noise floor with and without SnubWay.
  • Without SnubWay: The plot shows a jagged noise floor with peaks spiking across 100 kHz to 1 MHz, reflecting SMPS interference leaking into your AC mains. These spikes muddy your sound, masking detail and depth.
  • With SnubWay: The line flattens dramatically, dropping noise by up to 28 dB. Our four discrete LRC filters—featuring nano-graphite pulse absorbers, premium capacitors, and copper inductors—snub this chaos, leaving a smooth, quiet baseline.
The result? A darker sonic background, sharper soundstaging, and richer bass—proof that SnubWay transforms your setup. Plug it in and see the difference for yourself!

Impact on Headphone Audio

Impact on Headphone Audio Performance.” The x-axis represents frequency (in kHz), ranging from 0 to 25kHz, covering the audible range and slightly beyond. The y-axis measures noise level (in decibels, dB), from -80 dB (quiet) at the bottom to 0 dB (noticeable noise) at the top.
Two lines run across the graph. The first, a jagged red line labelled “Without Main Stream,” fluctuates unevenly, peaking around 10kHz to 20kHz with spikes reaching -20 dB, showing AC interference and RF noise like hum or hash audible through headphones. The second, a smooth blue line labelled “With Main Stream,” starts at a similar low level but drops steadily from 10kHz, hitting -60 dB by 20kHz and staying low. This illustrates how the Main Stream filters RF interference in the 10kHz-20kHz range, reducing noise significantly.
A shaded area between the lines highlights the “Noise Reduction Zone,” peaking at 20kHz, where the Main Stream cuts interference most effectively. Annotations note “Cleaner Soundstage” and “Sharper Detail,” linking the drop to improved headphone audio. The graph visually proves the Main Stream quiets AC noise, delivering a purer, more immersive listening experience.
 
 
 
 
 
 
 

Enhancing Your System with SnubWay and Main Stream

 
Vera-Fi Audio’s SnubWay and Main Stream AC line conditioners work together to transform your audio system by eliminating electrical noise that degrades sound quality. The SnubWay targets high-frequency interference from 10kHz to 2MHz, with peak effectiveness between 400kHz and 600kHz, neutralising the disruptive noise from switch-mode power supplies (SMPS) found in chargers, LEDs, and appliances. This results in a darker background, reduced hiss, and enhanced clarity, allowing subtle details in music or dialogue to shine through. The Main Stream focuses on RF interference from 10kHz to 20kHz, smoothing out hum and hash near the audible range’s edge. This delivers tighter bass, crisper treble, and a wider soundstage, making your system feel more dynamic and immersive. Together, they create a cleaner power supply, unlocking your equipment’s full potential – whether it’s a hi-fi setup, headphones, or home cinema.
Integrating them into your system is simple, thanks to their parallel design and the included quality UK adapter plug. Start with your extension lead (power strip) that powers your audio gear. Plug the SnubWay into an available socket on the strip – it doesn’t need to be in-line with your equipment, as it works by absorbing noise across the circuit. For best results, place it close to noisy devices like routers or phone chargers on the same strip. Next, plug the Main Stream into another socket on the extension lead, ideally near your amplifier, DAC, or primary audio component, to target RF noise at the source. If your strip is full, use a second extension lead connected to the same wall outlet and distribute them similarly. No rewiring or complex setup is required – just plug in, power on, and enjoy the immediate uplift in sound quality. With their sleek design and UK-compatible plugs, they blend effortlessly into any setup while delivering professional-grade performance.
 
 

I bought 3 of them, 2 for my desktop system and 1 for my surround system, all plugged into the first outlets of power conditioners. They provided clearly audible improvements in sound quality and enhanced my enjoyment of the music, more nuances, better dynamics, bigger soundstage…..For the money, they are an excellent value for upgrading highly resolving systems.

I am gobsmacked by the improvements in sound quality right across the board. The blacker background has improved clarity dynamics with more realistic 3D holographic imaging. The overall sound off my system is smoother but in a wonderful way, very addictive!
 At this price point they are a no brainier to try they have replaced in my system a highly sought after $9000 mains conditioner. 
 
they offer extraordinary performance and are an outrageous bargain!

The SnubWay reduces high-frequency noise (10kHz-2MHz) from devices like chargers and LEDs, delivering a quieter background and clearer sound. The Main Stream targets RF interference (10kHz-20kHz), enhancing bass, treble, and soundstage depth for a more dynamic listening experience.
Plug the SnubWay into an extension lead or wall socket near noisy devices (e.g., routers). Connect the Main Stream to the same power strip as your audio gear, like an amplifier or DAC. Both come with a quality UK adapter plug for easy use.
It depends on your needs. SnubWay tackles higher-frequency SMPS noise, while Main Stream focuses on RF interference. Using both provides comprehensive noise reduction, but one may suffice depending on your setup’s noise sources.
Yes, both improve audio quality across systems. For headphones, expect reduced hiss and sharper detail; for speakers, you’ll hear a wider soundstage and tighter bass.
Absolutely. At a fraction of the cost, they rival high-end units with advanced filtering (LRC filters in SnubWay, RF smoothing in Main Stream), offering exceptional value and performance.
While designed for audio, they can reduce noise in any AC-powered setup (e.g., TVs), though their benefits shine most with sound systems.
The effect is immediate once plugged in. You’ll hear a cleaner, more detailed sound right away, though it may take a few listens to fully appreciate the improvement.
No, they’re maintenance-free. Just plug them in and let them work – no adjustments or upkeep needed.
