What SnubWay does
What SnubWay does
You know how most modern gear—TVs, chargers, fridges, even that smart light bulb—runs on switched-mode power supplies? They’re efficient, but they dump a ton of high-frequency noise back into your mains.
That noise leaks into your audio chain—even if your setup’s ‘separate’—and messes with dynamics, clarity, texture. SnubWay acts like a noise vacuum for that mess. You plug it in near your system, and it passively clears out the crud those appliances feed into your wall.
It’s not voodoo. It’s science. And once you hear what your music sounds like without that everyday noise riding the line… you don’t go back.
Avoid getting down the rabbit hole —$2,000 power conditioners, regens, audiophile cables with ‘tuned’ dielectric geometry. Some were fine. Most just looked impressive.
What makes SnubWay different? It does not re-invent your power. It just targets the *actual* problem—noisy signal from SMPS and household junk. And it does it without drama. No switches, no LCDs, no ‘smart’ circuits trying to justify the price tag.
SnubWay’s like a silent worker. Not glamorous. Just clean, effective, and reliable. And for once, you won’t feel like you are paying extra for marketing fluff.

How It Works
Watch this SnubWay prototype (ParaSnub) demo by Dr. Viet Nguyen and discover how it can transform your setup!

"First, I'd like to thank **Mr. Ace**. He was a great help with the delivery.
The **SnubWay - Noise Defender** has enhanced the audio system. A new level of sophistication has been added to the system, which was previously a straightforward 'Main Stream' setup.
Firstly, I feel like the **soundstage is wider**.
And I feel like it has captured the **subtle vibrations and noise**.
Frankly, I had been briefly tempted by Chinese-made products due to their price advantage.
However, **vera-fi-audiollc** clearly demonstrated the **technical gap** between those products and this one.
Thank you."
Made a huge improvement in my system.
Placing the SnubWay into my high end system reduce the background noise .It has made things a lot darker ,everything is quite and it make the music much more enjoyable. I have had a few of my audiophile friends over and we listen to my system with it in and out. Everyone of them left my house in disbelief that it made that much of a difference in. Now they are all thanking me and purchase the SnubWay for there own systems. I highly recommend trying the SnubWay. Happy listening 🎶.
I took a flyer on this during one of the occasional price reductions by Mark. Given the glowing reviews, Vera-Fi's generous return policy, and the reasonable cost, I decided, "why not, can't lose?"
So, I received the SnubWay, popped it in the the second outlet of the duplex that feeds my power conditioner / transformer and promptly and completely forgot about it. I didn't listen closely much that week, my system was mostly providing background music during several jam-packed days.
7-8 days in, I sat down and played some Pat Metheny, Beach Boys, Coltrane, and a bit of Yes. Sitting in the sweet spot, but working on the computer while doing so, I suddenly looked up and declared, "Wow - great clarity!" I don't think I've heard my system sound quite like that before.
Delighted, I started working less and listening more. A few records later, all sounding fresh and unveiled, I remembered the SnubWay. Coincidence? Who's to say? My system sounds so great these days, I haven't yet chanced removing the SW to test my impressions. I'm afraid of breaking the magic :).
When I finally do, I'll report back. But for now, this silly thing seems to be providing some serious good sorcery on my electrons...
Snubway improves sound stage and details and placement of the instruments on the sound stage. Using the combination of the Snubway and the Mainstream even further expanded the width and depth of the sound stage. Micro details become more evident.
Using both of these in the home theater provided better color saturation along with better overall sound!
In my 2 channel system the sound the sound became more holographic. A definite win-win for me. The more of these you add the more you'll gain.
Clearer sound and better separation of the music, heard more of the music.
This is my first Vera-Fi product. My system, except amp, runs through a 25# noise reduction Topaz transformer. The SnubWay still made a sonic improvement. There is a band of hash and grit in the lower highs that is greatly reduced. The system sounds so much more pleasant and relaxing.
This works so well, I purchased a 2nd SnubWay for the amp and a Main Stream for the complete system. Amazing improvement. The system now sounds the same day or night. I can listen for hours without fatigue. Highly recommended.
My Main Stream and SnubWay filters arrived a week ago today. I plugged both into the back of my power conditioner replacing one of your older Puron filters. (I was so impressed with the performance of your older filter that I decided to gamble on upgrading to this pair of filters.) They have been in my system now for about 140 hours. Listening at my normal level to my favorite tracks, the music was noticeable louder. As I listened, I realized that the overall volume had not increased but the dynamic contrasts within the music were greatly improved. I assume this was due to a further reduction of the noise floor. The other thing I noticed was that very subtle details in the background, bells, brushes on cymbals, wood blocks, while clearly resolved in the past, were part of a “sonic fabric.” That fabric was now gone and each of these delicate sounds now existed in three-dimensional space with a sense of air around them and their own dynamic range. For a guy like me, who loves hearing these inner details, my listening engagement went off the charts. Long story short, this pair of filters made my system more transparent, more engaging and brought me closer to the experience of listening to live music. If anyone out there is fence-sitting, debating on getting these, ORDER THEM! I have spent thousands on cable upgrades and not heard as big an improvement as these filters provide.
MIT Z-1 and Blue Circle BC86. Highly recommended!
WOW! 💥 I added the Main Stream unit first. After a good amount of break-in time, I started hearing the backgrounds in the music sound quieter. Instruments are a bit more focused in their own space. A subtle but noticeable improvement overall. Now I decided to try out the SnubWay. 48 hours in, no real change in things. Fast forward to about 500 hours of being in my stereo system (with the MainStream still in place) and I cannot believe what I am hearing! I have a much bigger soundstage right-to-left and the same for depth front-to-back. There's a greater separation of instruments & voices and yet there's more layering and detail in between. Anyone who cares about their music and optimizing the way your stereo sounds needs to contact Mark L. Schifter at Vera-Fi Audio. Of course, YMMV in your system. Tell Mark that I sent you!

Frequently Asked Questions (FAQs)
What is the SnubWay - Noise Defender?
The SnubWay is a device designed to reduce AC noise in your audio system, enhancing sound clarity and overall performance. SnubWay works on eliminating Switch Mode Power Supply Noise which poisons your AC Mains.
How do I install the SnubWay in my audio setup?
Simply plug the SnubWay into an available outlet on the same circuit as your audio equipment. No additional setup is required. We prefer any open Duplex on the Wall, but can be used with Power Conditioners if no open Duplex exists.
Will the SnubWay work with any audio system?
Yes, the SnubWay is compatible with a wide range of audio systems and components. If you have a Flat Panel TV in your home or use Wall Chargers for Mobile Phones, you will benefit from having a SnubWay.
Can I use multiple SnubWay devices in my setup?
Yes, using multiple SnubWay devices can further reduce noise across different circuits in your audio setup.
Why doesn't the SnubWay have an indicator light to show it's working?
The SnubWay operates passively to filter out high-frequency noise from your power supply. It lacks LED indicator lights by design, as its effectiveness is instantly reflected through improved clarity in TV screens and improved audio performance of the system rather than through visual indicators on the product.

I bought these because I have been in love with Rosewood veneer since I first saw it as an extra cost option for some $5000 speakers in the '90s. Never expected to be able to afford a pair of Rosewood veneered speakers, but then found these for under $300. I pulled the trigger, ASAP.
When they arrived, I gave them >50 hours of 85dB in room playback of the radio with them facing each other under a comforter and wired out of phase to damp down the noise. After this, I gave them a listen. Beautiful, and they sound spectacular for their price point. I felt like I won the lottery; a scratcher, not the PowerBall, but still :) I was used to a bookshelf pair w/ lite mid-bass response and slightly "crisp" highs, and these (in direct comparison) had excellent mid-bass response and are just a bit laid-back in the very highest registers to my ears. I use them with a 500-watt RMS ported 12" subwoofer crossed over at 100Hz and get good output from them with an 80-watt per channel RMS amp. Like easy, no strain, >90dB at the listening position 12' away kind of "good output". For movies, tv, and music. Plenty for me.
If you like beautiful speakers, good sound (though not detail monsters like the AMT-tweeter based speakers I have in the bedroom), and spectacular value don't be afraid to pull the trigger on these Vanguard Scouts. Just please don't expect "giant killing" sound quality for under $300, and I promise you'll be happy with your purchase.
I’ve never had good speakers to listen to music on, so this was a big leap for me. I bought the Vera link combo and the 10” caldera to go with them. Mark has answered every question of mine personally and he advised that I connect the vera-link to the high pass input and then out put with some cables to the speaker and it works like a charm! Even though I am listening to music through my bluetooth on my iPhone, it sounds absolutely amazing!!
Excellent built quality, a ported sub that sounds closer to sealed sub and for only 348 euros? Insane but true, the Caldera 12 will sound just as good in my room for music or home theater, i cant recommend this sub enough! Go dual for bombastic room filling low notes imo. The only gripe i have is the auto on off which turns the sub off after only 10 seconds, i would recommend at least 1+ minute of inactivity to turn off so lets hope they boys in the lab will sort this out on the next batches! Excellent job Vera Fi team!

This is my first Hi-fi set of speakers I have ever bought. Before this, I listened to BOSE speakers.
WOW.... what an upgrade these Vanguard scout speakers are!!
I had to wait a couple months to get my order (because of tariffs), but Mark and his team were really amazing at answering all of my questions and updating me with the progress of my order.
I ordered the Caldera 10 sub, vera-link amps, and the scouts and Mark helped me to understand how to plug the vera-links bluetooth amps into the subwoofer through the high-pass input and output through the high-pass directly to the right scout speaker and it works like a charm! I couldn't be happier!
You will see two pics in my review of the back of the right vanguard scout speaker, because I wanted to show you that if you have to peel the velcro off of your speaker and place it elsewhere, it doesn't leave any residue to clean up! It's not a huge deal, but it certainly made my life easier.
I am a fan for life and will be ordering some of the new things they are working on in the future!
I purchased three Caldera 10's to go with my three pairs of Scouts. I love them, so I purchased 4 more to get small rooms 2.1 & large rooms a 2.2. I love speaker systems but I haven't had a good set up for years. I looked into this for months. I didn't know what my sound system was missing till I got the lower end filled in.
Great speakers, right in my budget. I purchased one pair, broke them in, loved them, and then purchased 2 more pairs. I had the option of ceiling speakers but bookshelf sound so much better. The Scouts allowed me to get great sound and budget. I have them in several rooms now. 2.2 in the main rooms and 2.1 in the small rooms. When connecting a Caldera 10 it was suggested to put a HPF 70h on the Scouts. I haven’t been able to find a good low cost 70h, closest so far is 80h $25. I purchased (3) pairs of Scouts and (7) Caldera 10. So HPF is important to focus more on the mid and high’s. Really really like Vera-Fi Scouts and Caldera’s!!!
Great product , great prices and good follow up when required.
Good price, looks great, well made -suits the scouts perfectly
I had my eyes on a Caldera 10 subwoofer for quite a while before I decided to take the plunge, but I'm really glad that I did. I initially had reservations for how low the price was for what it claimed it could do, but eventually a sale came along that was a little too good to resist and I purchased it for $149.
I imagine myself and quite a few other people ended up ordering around this time and it took some time before my order was fulfilled. Additionally, there were significant delays in shipments due in part to ongoing changes to US import policies, but Vera-Fi diligently kept me updated throughout the process, even responding to my emails I sent with questions. In hindsight, I am glad I was patient and waited to receive mine.
Though it took some time, in the end, I received a cute little compact subwoofer to pair with my budget living room setup and have been very pleased with how musical and quick it is, as well as how much it filled out and enriched the music for a pair of smaller bookshelf speakers. I don't think there is a better budget sub for a 2.1 stereo setup for this price. The Caldera 10 is a product that knows what it is and does it damn well.
Highly Recommended.
