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.

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!

Over the years, I have put the majority of my audiophile / videophile time and money into the audio side of things. On the video side, I have a great LG TV / Monitor with a decent amp and speaker combo for sound. On a lark, I decided to pull the trigger on a Vanguard Caldera 10 sub, figuring that for the price and with Vera-Fi’s generous return policy, I couldn’t go wrong. Frankly, and in spite of the many favorable reviews, I really expected nothing more than thumpy, one note bass.

Surprise! The VC10 is tight and tuneful and highly adjustable. I was able to dial in the sub quite easily to add the bottom octave / octave+ to my video system, without overblown low-end out of sync with the rest of the frequency spectrum. It’s a remarkable phenomenon, but as I have experienced with a much more expensive sub in my audio system, adding the bottom octave or two somehow brings a greater clarity to mid and high frequencies. Part of this I suppose is the fact that I can eliminate the bass boost on my main speakers I had dialed in an attempt to get more satisfying sound. The mains are not working as hard now with the sub in place, greater clarity is the result, or so it seems subjectively.

Anyway, this sub is a winner. Can’t go wrong in my humble opinion…

I have a Snubway Noise Defender and a Main Stream conditioner in my system for a while now and they definitely improved the sound quality. However I recently added another Mainstream and placed it in the electrical outlet near my broadband router. I noticed another improvement in SQ almost immediately and it seemed to gradually get better and now about 150hrs in it is truly amazing. The sound from my system is gone to a whole new level, especially the bass which seems to be much tighter and is a joy to hear. Overall a major improvement. It is astonishing how these little units are capable of giving a lift you would expect from a component or cable upgrade

I have 2x Snubway + 2x Mainstream plugs connected to my Ansuz power distributor. My system never sounded better!

I was initially skeptical, but there are really safely amazing to use...even in very high-end systems.

It is a incredible improvement in quietness

I was curious to see what such a little "device" might produce in my system, if anything.

Opening the very nice Asian inspired packaging revealed a little creature about as big as my thumb. Very nicely finished with a chrome spike for it's tail (where a ground is to be attached) it certainly qualifies as "cute", but not so inspiring as an audio tweek. The mystery is enhanced by the fact that no literature is supplied or even referenced in the product description, so I had no idea what sort of change I was listening for. And THAT might be the magic - ANYTHING sounding different can thus be attributed to the Meow?!

What I'm getting at is that my expectation bias was very low. I couldn't fathom how this cute little chunk of metal with a ground wire mashed to its butt would accomplish anything. More $ wasted on foolishly audio pursuits? Again?!

As soon as the lights went low and the music came up from the black velvet background... "WAIT A MINUTE! WHEN DID THEY ADD SPOTLIGHTS TO THE STAGE?!"

I was caught off guard when I sat down to listen and noticed a distinct highlighting of solo instruments or whatever the central attention point was! Not just a constant illumination of center stage, but anywhere between the speakers that the main instrument or voice is featured. For me, it was an interesting and ''illuminating" experience that has continued to elevate my sonic enjoyment.

Highly recommend IF you've maxed out your system and can afford to play with mystical (possibly stupid) quantum theory based tweeks!

I bought the Snubway to improve the sound in my mid-fi setup. When I plugged it in, I immediately noticed a lower noise floor. Within a few hours, I began to notice increased sound stage as well. Another unplanned benefit was increased definition on my LG OLED tv. This thing works as advertised.

Mark and staff were a pleasure to deal with. Great experience!

The first 30 hours I heard the potential but the tone seemed off. Now about 60 hours in I am totally blown away! The biggest improvement is the soundstage and imaging. The SDFB on my amp has freed the music from my speakers. It is just there, in front of you. The speakers disappear (hard to do with 5 foot tall, 2 feet wide Acoustats). The depth is incredible! The background is quiet and black, details just jump out of the mix. Amp seems more powerful, more dynamic.
I still think it would be even better without having to use another separate power cord, and I intend to try to use adapters with the SDFB to compare against the Piggy. But the Extreme Piggy is very good.
This is one of 5he best tweaks I have tried. Highly recommended!
