This is a joint review of the Mainstream and Snubway, purchased together. The units are substantial and very well constructed. Experimented with different placements, before settling with the Main Stream in first receptacle of my PDU for the sensitive analog units. The Snubway is plugged into the first receptacle of the PDU for the Home Theatre noisy electronics. Both are doing an excellent job in limiting noise from smearing sound and vision.
I already use several of the Mainstream devices to great effect. I bough 1 SnubWay at the advice of an audiophile colleague of mine. I placed it in the mains outlet under the AC connection to my Puritain 156 power and grounding device. I was shocked by the improvement in nuanced detail and a blacker noise floor. Just for fun I plugged 1 into my TV outlet, and wow. Now I have no choice but to buy another one. Oh well.
Excellent products that have improved the sound of my system. Not a subtle improvement, very noticeable and brings greater enjoyment to my listening sessions. Highly recommended.
Another outstanding value. Well made, well balanced cables. Everybody can have nice high end cables even those on a tight budget. Well done!
Thank you.
This company needs to be put out of business. Countless excuses why they could not deliver merchandise. Look up the owner, Mark Schifter, and you will see he plead guilty to scam charity schemes. How low can an individual go? The level of greed and deceit is legendary.
Noticeable improvement in sound quality - highly recommended
I pre-ordered a Caldera 10" sub during the 2025 Black Friday sale. I understood the product would have to arrive from China, clear Customs, and be delivered to Vera-Fi's warehouse, etc.
Time marched on but there were always excuses: problems at the factory, congestion at the port, the Lunar New Year holiday.
Finally, I got some good news: "Your order has officially left our hands and is now enroute to you." A check of the UPS tracking number showed a shipping label had been printed but they had not received the package.
More excuses: UPS won't send a truck to pick up the 90 subwoofers labeled and ready to go but we'll rent a truck and deliver them to the UPS distribution center ourselves.
Never happened. The UPS site still says "Estimated delivery date will be available when UPS receives the package."
I requested a refund. Instead of my money in "3-5 banking days" I got a request to leave this review.
Probably a scam. Still haven’t received anything.
Hi Mark, i’d love to post a five star review, but unfortunately, I never received my subwoofer!
Can you refund my purchase price or send out another unit? Please let me know if you need anything from me to resolve this. Thank you! John.
Superb product. Increase in transparency.
I ordered this item late last year, nearly six months ago, and I still have not received it. This delay is very disappointing, and I would appreciate an immediate update on the status of my order or a prompt resolution from the seller.
Waiting 5 months and still never received item.
Have not received it. I purchased it in September and still don’t have it.
C'est un tweak majeur qui se veut indispensable pour amener votre système à un niveau que vous ne soupçonniez pas, sans aucune contrepartie ; votre chaîne hifi est déjà d'excellente qualité, les SDFB la libère de tout stress, de toute crispation sonore, ouvre la scène, augmente la transparence, magnifie les ambiances sonores, révèle enfin le jeu des contrebasses ...Tout cela en protégeant vos appareils et en rendant les fusibles audiophiles obsolètes et ridicules ...
Pour moi , ce n'est plus du tuning , c'est une optimisation incontournable .
Ajoutons que Mark Shifter est très communiquant et bienveillant avec ses clients ; un vrai gentleman !
(1 SDFB MAX sur chaque amplificateur, 1 SFDB silver sur le streamer le dac et le préamplificateur)
I bought these speakers for a nice garage system but during the break in period they displaced some speakers that were in the house system. If verify developed a slightly larger bookshelf it would be ideal!
As with all of the Veri-Fi products, in my opinion, exceptional value. Good balance and very musical meaning all of the music comes through in a full engaging experience. Well done !
Despite the very long wait time to receive it (~2 months), it is just as described, seems quite well-built, and sounds quite good.
Great Product, highly successful in improving video/sound quality
So good I am going to order a couple more. I heard a difference when I let the current flow.
Received 2 SWDFs about 5 weeks ago with the graphene sluggos.
Things were sounding good before I introduced them to the system but there was a definite improvement in resolution and detail after I did - especially after several weeks of burn in time.
I purchased these speakers direct from Vera-Fi and I do agree with the great reviews out there. I have demo'd or owned many bookshelf speakers over the years so I do have some experience here.
The slightly boosted midrange makes these sound bigger than they are and that also makes them quite pleasing because the dialog from movies or tv are projected very clearly. The bass is also very good for their size.
Furthermore, I am also quite impressed with the veneer and fit-n-finish of the speakers for the price. I very much recommend them to anyone looking for bookshelves under the $4-500 range.
The Graphene is a worthwhile upgrade from the copper or brass SLUGGOs. I've got 3 and will order 2 more. Highly recommended!
This ac line conditioner has made a significant improvements on my already sonically upgraded cables and ac filtering on my two hi fi systems. Try it you’ve nothing to lose. Hear what you’ve been missing.
