Fantastic. Amplifier producing bigger sound stage and instrument separation. More resolution but not harsh. Less tense, more musical. Makes me want to listen.
This is my second Snubwayand I have had one for my audio system and it made an audible improvement. This second one is for my new tv and soundbar. Again a visual and audible improvement. Smoother clearer sound and sharper and clearer picture. Well worth the modest cost. Highly recommended!
Include instruction to handle graphene sluggo with minimum contact when installing
With so many portable plug-in noise filters on the market, some of which I have tried and implemented in my system(s), I was leery of the SnubWay but decided to give it a try. I was not too impressed at first when implemented in my 2nd system as it caused an upper frequency glare when placed in the outlets in the listening room. With some experimentation, it became clear that placement was the key to extracting its full potential with one place being most effective and that was in the dining area where we have our laptops. Placing a SnubWay on that circuit had a substantial improvement on the systems resolution and noise floor. Unplugging the laptops was also shown to reveal additional reduction in noise. Highly recommended but experimenting with placement in one's home is key to extracting its full potential.
I have had the Snubway and Main Stream plugged in my system for about 2 weeks days now. On the first day I was not blown away by what I was hearing. I did notice some improvement in clarity and reduction in noise floor, but it kind of left me feeling underwhelmed.
Fast forward to three days later and when I sat down to listen I was like "Wow". Something had changed for the better - by a lot. I was now hearing much more clarity and the reduced noise floor allowed me to hear more low level detail in recordings. I noticed for the first time room ambience in some jazz recordings that I had not picked up on before and the music overall seemed to reach out and pull me in more than it had previously.
I tried various positions for the devices and for now have settled on the Snubway being in the duplex outlet that my power conditioner is plugged into and having the Main Stream plugged into the first outlet on my power conditioner. This configuration was recommended by Vera-fi and seemed to work best for me. When I removed either one of the devices the result was less than when using both.
Mark from Vera-Fi was very helpful with any questions I had. Highly recommended to try.
In a nut shell: Snubway and Mainstream combination has cleaned my audio as much the best painting with excellent details and texture covered with dust for years comes to life when the dust is cleaned. Picture hasn't changed, its the appearance that is now more appealing. Just this way these devices makes music pop up.
I wouldn't give what has improved on which of the track, because every track sounded awesome, very detailed to me. I don't want to leave it to your imagination rather wanted you to experience it.
While some may consider the effect to being bright due to increased resolution, but truly that is how probably your system with good power supposed to sound.
There may be several other products with similar offerings and if you have time to experiment, fine try your best fit, otherwise these are real stuff at a very affordable price. And if you are a person like me, would spend time enjoying the music then think no further, just add Snubway and Mainstream. Mostly you will not regret with your decision.
I would say buy it, plug it, sit back and relax for a week and then thank yourself for the decision to buy it otherwise avail the 30 day money back guarantee. Whatever don't decide to unplug it without running atleast for 100+ hours, 10 days to the best.
Detailed review:
Friends if you have time read thru the entire review to get a feel of my experience.
I am a real person, an audiophile, paid purchaser of the products, not a reviewer paid or affiliated to any publication nor have any affiliation with the product(s) or the company nor here to influence your decision.
My setup has power conditioner (Synergistic Research Powercell SX) and multiple power enhancers (from High Fidelity cables, Add-Powr Sorcer 4 and Synergistic Research various products) including the well acclaimed power cords (Synergistic Research SRX and Galileo) that are supposed to eliminate noise. Absolutely no product using SMPS, only LPS from Sean Jacob and Farad even on network devices including modem, router and all network switches in the chain. All external PSUs use Core power technologies Diamond xtreme power cords. And most importantly the entire audio network is on a seperate circuit with 30A breaker on its own. I was very happy with my setup.
In my interactions Mark recommended to try Snubway. I mentioned to him I already have several power enhancers in my setup and will these really add or do anything different. Mark very confidently responded, based on what his customers experiences was it will, give it a try. I very reluctantly ordered to give it a try, not because they are expensive but because of the efforts and time involved to spend on it.
Here's the summary of my experience:
Upon plugging Snubway and Mainstream to the main power receptacle that feeds the entire system, I heard something different happening.
At first the change I heard was in the lower frequencies, which was also my observation with most other products that are made of pure copper. The experience was OK as it isn't the final state, results can go either side after few hours of listening. The best part even at this stage is nothing is added or removed, I could enjoy music as before.
Day 2 (after 30hrs+), I haven't heard what my experience has been the first few hours of plugging in. Music seems to be sounding more closer to how it was before adding these devices, but a little more details poping out from a very far off distance. Day 3 thru 5 (36hrs to 100hrs), gradual improvement especially tigher bass compared to the previous days as well as details popping out closer as it aged connected and powered. I don't shut my audio equipment, leave them on always except when away for more than a day or bad weather conditions.
I usually play audio at moderately higher volumes especially when recordings are too good and wanted to enjoy every detail. At about 100hrs+ of use, due to an unavoidable situation I had to play music at considerably lower volume, almost 2-3db down from my normal listening volumes all that day. Interestingly, in my listenings that day I never felt a need to raise volume even for those existing moments. Every detail popped up crystal clear, just like how a painting would show cleaning dust from it. Imagining and soundstage from my original audio equipment is unaltered, just the stress is relieved.
As days passed it just added more excitement forcing me to listen again every track I previously enjoyed. At this stage I decide to go back to earlier setup, so, unplugged both Snubway and Mainstream from the chain. I could hear the difference immediately, but this time felt it a bit dull.
Not being sure, to double verify whether it is a placebo effect or real, plugged Snubway and Mainstream into my multi-channel HT. My HT setup too is equally powered with power conditioner, enhancers and power cords similar to audio setup. Surprisingly, same impact on audio there too and interestingly video improved to a gr...

Purchased two of these. One for my integrated amp and one for my DAC. In the end, floored by what it did for the amp, opening up the air, solidified the bass kick and added lower mid-range weight. My DAC was another story, sound got hard edged and a little too shouty for my tastes. Another reviewer stated that someone may or may not like what it does. So, as the title suggests, take the time to listen to what it does before making a judgment. That said, another 5 stars for Mark at team at Vera-Fi. Answers email questions quickly, fought through the CA fires, and still did their best to take care of customers.
This is an excellent purchase for the price. It added the additional bass I was looking for and has its own volume and bass dials to adjust to your taste.
Marvellous. It’s improved the sense that even at higher listening volumes, I can still hold a conversation with someone next to me. Less wall of sound, more clarity. A nice improvement indeed. Once you hear it, you can’t “unhear” it :)
I have 2 Caldera 12 subs. My wife think they look great and I love the sound of them. They blend so seamlessly with my Spatial Audio open baffle speakers. My only issue is with the auto on/ off…. It cuts off too quickly when no signal is present while the music is playing and then it cuts back on when signal is present while the music is playing… the problem is the switching on/off is audible. It distracts from the illusion of musicians playing in front of me. Of course I just leave them on now for a work around. Other than that it is a great piece of equipment that I am proud to own… to say nothing of its price/ value and quality. It sets it apart from a lot of budget subs and on par with the best
今天对 MainStream的位置进行了AB交换比较：
从数字播放线路（数播、解码、usb重组）的总墙插 挪到 耳放线路总墙插后，与SnubWay#2 搭档（同样数字播放线路也有 SnubWay#1设备），效果还真有点让人惊喜。
低频明显沉得更深了，不是那种轰头的胀感，而是扎实又有层次的下潜，听着挺舒服。动态也更有活力，声音的力度和起伏都更清晰，尤其是听大编制或者鼓点强的曲子，能感觉到那种冲劲。
空间感也开了不少，声音不再闷在一起，定位清楚了点，空气感也好了一些。
刚换上去一耳朵就能听出差别，虽然不是翻天覆地的变化，但这种细腻的提升真挺抓耳的。降噪做得也稳，背景干净了，低频和氛围感都有加分。
对喜欢低频质感和宽松听感的玩家来说，这俩组合还挺值得一试，性价比挺有吸引力。MainSream在我的系统中更适合耳机放大线路。
Awesome…brilliance that’s shines through and through … lows are superb and mid range is spectacular … never overbearing and true to the original recording …Simply outstanding !!!
I wanted to share my impressions of the SDFB. I’ve ordered one SDFB (20A) for my Sanders Magtech power amp. I ordered the box with the graphene sluggos.
I’m using SR Research fuses in my entire system. Mostly Masters and some Purples. So below impressions are vs these SR Fuses and not vs stock fuses.
A difficulty here in Europe was the US socket on the output. I was only able to use the SFDB with the provided pigtail. This silver plated pigtail didn’t do it at in my setup. Timbre was synthetic and images were flat.
So I ordered a Schuko to IEC adapter. With the adapter I was able to connect the SDFB directly to the outlet in my power bar. Also, I ordered a US male to Schuko adapter for the output. Now I could connect any power cable at home finished with Schuko plugs. None of the adapters was „hifi-grade“. Just standard products from the electronics shop.
Using these adapters instead of the pigtail completely transformed my experience with the SDFB. I strongly advise anybody to use such adapters. I think Mark and the team are currently working on hifi-grade adapters With the adapter I was absolutely blown away by the result. The soundstage had increased a lot in terms of height, width and depth. Better than with the Master and significantly better than with the Purple. While the Master fuse tends to suck out lower mids, the Purple fuse emphasize this specific frequency range. So in combination this works but it needs attention and the willingness to balance things out. The fuse boxes frequency range remained neutral in the best sense. So there is no need to compensate anything in the process, like maintaining body and musicality with switch of cables, tube rolling, etc. It is thus a very clear improvement over both SR fuses.
Also seperation was clearly improved without loosing musicality.
The timbre was phenomenal: organic and natural. The sound had body and heft if the recording allowed for it. With leaner, airier recordings, it was open and spherical. There was a significant increase in micro and macro details.
The fact that the fuse box outperformed the SR Master and Purple in my amp, makes it very appealing. Also, fuses have blown in the past increasing the costs.
After the positive experience, I ordered more SDFB to upgrade the entire system. I observed the same improvements with every change. Maybe just slightly less of it the more I swapped but every single upgrade was very well worth the price.
I can strongly advise anybody to check these out. These are a phenomenal improvement for a very fair price.
我的系统有两条HIFI专线：
A线路：Aurender N150，Innuos Phoenix USB Reclocker，精音DAC-D1000 MK2（R2R）。
B线路：小不点LD-Y3全平衡300B胆机耳放。
从国外论坛中了解到Vera-Fi Audio的SnubWay和Main Stream这两款降噪新品后，我联系了Mark。在30天免费退货的条件下，我尝试了这两款产品。此前我用过日本Furutech NCF Clear Line电源净化器和美国Shunyata Research Venom Defender电源优化调谐器，但效果不够明显，也不够理想。按照Mark的指示，并联设备需要通电400小时才能达到最佳状态，目前我的通电时间已接近400小时。
由于SnubWay和Main Stream体积较大（三角形设计），如果和电源线一起插入美标插座，空间不够，所以我自制了几条公母转接线来搭配。我将SnubWay（2个）和Main Stream（1个）放置在以下位置：
SnubWay #1：插入A线路的Sierra 20A镀金背插座，通过Hubbell橡胶插头转接线与CARDAS Clear Power电源线并联，供电给Aurender N150数播。
SnubWay #2：插入B线路的A&H-H 6262-2 DELUXE电木插座，通过电木插头转接线接入，与A.R.T. AC-8 G1电源线并联，供电给小不点LD-Y3耳放。
Main Stream：插入B线路的Hubbell 9595 + HUBBELL BK-12433总墙插。
听感上的变化：
加入这三个并联降噪设备后，我试听了熟悉的曲目，包括交响乐（如马勒《第二交响曲》）、人声（如蔡琴《渡口》）和爵士（如Dave Brubeck《Take Five》）。整体听感提升明显，背景黑度更深，细节更清晰。以下是具体变化：
背景黑度更深，细节更清晰
在A线路加入SnubWay #1后，数播端的背景噪声明显减少。播放《渡口》时，蔡琴的呼吸声和低频鼓点之间的空隙感更强，细节浮现得更为自然。以前偶尔能察觉到的微弱“沙沙”声几乎完全消失，背景变得像“墨汁般黑”，让人更专注于音乐本身。
声场扩展，3D感增强
Main Stream在B线路的加入对声场影响显著。听《第二交响曲》时，乐团的纵深感和定位更立体，弦乐组与铜管组层次分明，仿佛能感受到乐手之间的距离。相比之前，声场宽度和深度都扩展了不少，3D包围感让人有种“置身现场”的沉浸感。
低频下潜更深，纹理更丰富
SnubWay #2和Main Stream在B线路的协同作用，让耳放的低频表现更上一层楼。《Take Five》的鼓点下潜更深，力度感更强，同时低频的纹理和扩散感也更自然，不再有那种“糊在一起”的感觉。尤其是Main Stream加入后，过滤了家电电机噪声，低频的氛围感更浓厚，整体听起来更松弛有力。
人声情感更细腻，动态更宽松
人声方面，《渡口》中蔡琴的声音轮廓更清晰，情感的起伏和喉韵细节被放大，显得更有温度和感染力。动态范围也有提升，弱音到强音的过渡更顺畅自然，没有之前那种轻微的“压迫感”，乐感变得更抓耳。
整体氛围感和乐感提升
三者搭配后，系统整体的氛围感明显增强，音乐不再只是“精准还原”，而是多了一份活生生的生命力。无论是大编制的恢弘，还是小编制的情绪流淌，都让人更容易沉浸其中，长时间聆听也不觉得疲惫。
Vera-Fi Audio的SnubWay和Main Stream作为并联降噪设备，在我的系统中发挥了“锦上添花”的作用。SnubWay的高频噪声过滤能力让前端和放大环节的背景更干净，而Main Stream在低频和动态上带来了惊喜，两者协同工作将系统的潜力进一步挖掘出来。这三件“手雷”性价比很高，绝对是“调音利器”。
在使用这三个设备的过程中，Mark非常热情，有问必答，让我感到很亲切。我愿意尝试更多Vera-Fi Audio的产品，Mark很专业，同时也要感谢Mark的同事Peter。有时候对于Hi-Fi玩家来说，有些东西看似玄学，但其实背后有更多科学技术的支撑。Vera-Fi Audio的产品物有所值！
Very happy with this purchase. It gets better and better with time after 150 hours. Blacker and more live sounding background with details sounding more present and perfect. Would recommend this Snubway and Mainstream for a perfect combination and experience.
Really impressed by the addition of this box and a graphene "fuse."
A wider and deeper soundstage, instrument separation with fuller bass and crisp treble, and much more detail.
Installed on my Nadac Merging, I've ordered a new one for my amp.
Thanks, Mark.
Thank you Mark and your Teams,
I have received the amps yesterday evening.
After about 2 hours playing ,the amps were
Synchronized to my system.
Honestly I have played quobuz and Tidal
from my iPhone 15 to the amps by Bluetooth
But they are so great almost closed to my Stello
Class D 15 years old. My speaker are Tekton Perfect Set 12.
This is the great pleasure to know You and your Teams for new experiences in my audiophile’s journey.
So Could I play with android phone to these amps in future?
Replaced all fuses in my system, about 10 in total. A very worthy investment. Thank you Mark
Greetings to all the HiFi aficionados, Mark and his team regarding the SnubWay and Main Stream have conservatively promised but in fact have over delivered. Prior to purchasing both of the foregoing units mentioned, I spoke with Mark.
He made the time and on a weekend no less to speak with me and called me back immediately and personally after receiving my request. Mark took the time to explain the units and should I not be satisfied a refund will be issued.
Let me say this, Mark's kind and easy going demeanor as if we had known each other for years made my decision easier. That said, both these units have proved to be one of the best, if not the best upgrade to my high end system. I typically do not write any reviews and can count them on one hand.
The units immediately delivered what they were designed and built to do. In fact having them now in my system for about 7 weeks have exceeded my expectations and their very own marketing. This entire review although is my respectful opinion it is not based on subjective perceived results but rather results well grounded in reality.
My system although high end had immediate and marked auditory improvements including but not limited to, clarity, width, height, depth and the extra details revealed by lowering or eliminating significantly the noise that inherently exists in all our power lines.
Mark and his team have made a believer out of me and I applaud them on their integrity and delivering on the promise to better our listening experience. What more needs to be said!!!
I have bought the Mainstream AC conditioner and the Snubway as well a few weeks ago. I can say that I was a little sceptical because I have a very high revealing system ,so how much better can it get? Well the first 150 hours were very subtle in audible differences but something was going on as I was starting to feel the music differently.The week after, I started to play some vinyls and WOW! I was so excited that I had to write to Mark to tell him he’s got 2 great products.The music sounded more live and detailed with a great soundstage pinpointing the instruments a notch above before. I need to mention a thank you to Mark, a real gentleman. He will answer any questions you may have regarding any issues you may have.I recommend both products as they complement each other.Thanks again to Mark and can’t wait for his next winner.
Excellent product yielding much better results than expected. Especially when paired with a Snubway noise defender. I am definitely considering another pair in the near future.
Having already experimented with a range of aftermarket fuses in my system, including the AM Ultimate Premier, AM M1, SR Orange, SR Purple, SR Pink, SR Master, Hifi-Tuning, and Gustard, I have developed a particular fondness for the SR Purple, Pink, and Master fuses, owning multiple units of each. After encountering several positive reviews about the SDFB, I decided to try it paired with the Graphene Sluggo in my Lampizator TRP II DAC.
The Lampizator TRP II is highly responsive to tuning components, making it an ideal candidate for the SDFB. The results were nothing short of remarkable. The soundstage expanded, the dynamics of the music became even more pronounced, and the spatial depth of the audio improved significantly. Additionally, all frequencies seemed to receive a more balanced enhancement. It was as though the SDFB took an already exceptional-sounding system and elevated it across every dimension.
Impressed with the performance, I immediately ordered additional SDFBs. In summary, the SDFB is an outstanding tuning component that delivers impressive results at a very reasonable price, making it a highly recommended upgrade for any audiophile seeking to refine their system.
Cheerz over the pond

I’m hesitant to assign a star ranking since my experience could be anything from 3 to 5 as you will see below. In all the many years that I've been seeking the absolute sound, I've always been hard-put to hear what reviewers called jaw-dropping improvements whenever they added some new something to their systems. I have the same difficulty with wines and with coffees; I simply don't pick up on the subtle differences that apparently are obvious to other people. And so it has been with the SDFB and the three different Sluggos I have used with it. To be fair my Gato 150AE and Aerial 6Ts already sounded far better to me than any amp/speaker combo that I have had in the past, so that it would have been asking a lot to for me to expect any profound improvement by adding something else to the mix. I like to think that I heard something new when I plugged in the SDFB with the copper Sluggo I started with, yet my jaw remained where it has always been. Don’t get me wrong -- everything sounded really good, just not bowl-me-over good. The thing I did hear, however, was a new glint, twang, sharpness (I’m not really sure how to describe it), something whenever a singer or a brass instrument hit high notes. Nevertheless, I didn’t want to risk losing even a subtle improvement by returning it within the 30-day window that Verifi graciously allows its customers. After a couple of months’ listening, I went back to their website and discovered that, according to Verifi’s description of it, I probably should have ordered the Super Sluggo to get more warmth from the fuse box. Hoping it might solve the problem with the sharpness I heard in high notes, I ordered a Super Sluggo. Unfortunately I honestly heard no difference between the two Sluggos. I suppose I should have returned it for a refund at the time, but for 30 bucks I didn’t want to look like a complete cheapskate. Another few months passed before I decided to go for broke with a Graphene Sluggo. (The discount at the time and Verifi’s praiseworthy return policy decided it for me.) I am happy to report that the Graphene so far seems to have resolved the harshness I was hearing with the highs in my system. As I said before, I don’t have the discriminating hearing that other listeners seem to have when they describe seismic improvements with every new addition to their systems. Your experience could be much different from mine. In all I’m happy with the way my system sounds now and while I might be slow to appreciate improvements that the SDFB and Graphene Sluggo offer, I wouldn’t remove them from the whole on any count.
I addded this to my system that already had the Swiss Digital FuseBox with an and a SnubWay, and I was already super happy with, then I saw Mark had said the Main Stream and SnubWay work great together and as usual he was right!
The MainStream added another level to the complete absence of interference with my digital gear and creates absolute inky blackness with added clarity.
Thanks for another great product Mark!
