Vera-Link TWS - Pair
David Tyler (Canal Winchester, US)
Great Company Great Products

These Vera-Link TWS Pair amps drive my Polk Towers well. The Bluetooth is seamless and connects perfectly.
Most impressive is the A+ care their management gave to me to satisfy my particular needs.
Thanks!!

Amazing transformation. Soundstage widened and was like a whole new system, for the better.

Oh my fuse !

I have experimented with many SR fuses and put SDFB in all components. It is like a new system after break in. Run don’t walk. Best enhancement possible, allows you to get full potential of your components. Best kept secret in audio. I’m in heaven and mark and team have enlightened hospitality and offer value in audio and don’t try and take the last nickel.

This is the most efficient way to enhance SQ in a system ilo of super expensive fuses.

SnubWay - Noise Defender
Andy (Sonoma, US)
Transformation In An All Streaming System

I just installed my third SnubWay, this time in the outlet directly adjacent to the one powering my Xfinity cable modem which is located in my garage. Wow. While I noticed a positive difference with the first two which are installed in each of the two 20 amps circuits feeding my system, but the impact of this third one in this location was off the charts positive. Powerline noise is insidious, and it's negative effects are really only apparent in your system when you take steps to significantly reduce it--the background becomes darker, revealing much more unforced detail and ambient cues, the soundstage expands in all dimensions, bass becomes tighter, deeper and more textured, etc. Highly recommended, and you have thirty days to experiment with it in your system. A no-brainer if there ever was one...

Immersive passion, exceptional quality, memorable experience...

It is truly a pleasure to listen to your favorite music and imagine being the original performance location, thanks to the outstanding performance of the Swiss Digital Fuse Box. There is hardly anything more to add, except for the impeccable accompaniment by Mark and his team. Excellent work!

Excellent hybrid decoupling

I didn't use the small spikes that came with the product, since I used mine in front of my PureAudioProject speakers.
Effective decoupling, thanks to the damping system under each VBH, a kind of rubber ring that stabilizes perfectly.

Sluggo - For Use with SDFB

Graphene Sluggo

I believe that it is the best accessory available to get the maximum performance from the SDFB.

Excellent

Nothing better at this price and I agree, you’d have to pay way more to get better or equal performance. Just prior to this I had demoed a JL Audio Dominion at five times the price and there was no contest between the two, the Vanguard was demonstrably better.
I use this for music only and paired it with some Gallo A’diva SE’s. IMPORTANT: this sub requires extensive break-in and didn’t sound its best until after about 100 hours and the change was dramatic.
The reason why the sub is so good for music is because it excels in medium and upper bass(where most music is played) yet still goes deep and clean providing a nice visceral and “chesty” feel that you expect with better subwoofers.
The sub is well-made, is not overly heavy and is easy to move around.

Very Good Sound Improvement

Nice contact, good shipping quality and good quality of devices.
I already own 4 pieces, and sound quality continued to improve.
Overall highly recommended!

SnubWay - Noise Defender

SnubWay Works

I installed my Snubway on the first outlet of my Niagara 1200. The reduction in noise floor was instantly apparent. It did not reduce music dynamics. Very happy!

Vanguard Scout - Pair
Peter Halliday (Scottsbluff, US)
Amazing for the price!

Surprising amount of bass. Definitely need the recommended break in period. Treble is "gritty" when playing loud. Work well with a sub woofer. Sound good in my surround sound system. I just ordered the Bluetooth amplifiers so I can use them in my kitchen.

Vanguard Caldera 12" Active Subwoofer
Peter Halliday (Denver, US)
Pretty Good!

I bought the vanguard caldera subwoofer to complement a pair of vanguard scouts. I connected it to my hifi rose ra280 via a skw rca to xlr cable. Signal sources are from an old, but good, denon cd player and an eversolo dmp a6 streamer/dac. All the vanguards look good in the rosewood veneer. After more than 50 hours of break in the subwoofer blended well with the scouts and didn't draw attention to itself after I played around with the volume and crossover settings. My only very minor criticism is that the red and green on/standby leds are too bright. I haven't yet finished moving my audio system around and settled on a location, but so far so good.

Just Amazing

I can't believe how much better my system sounds using the Swiss Digital Fuse Box. I have one on my PS Audio P-15 regenerator and on on my Holo Audio Spring 3 Dac.

The music has really opened up and so much more detailed.

Thank you!

Sweet Sound!

Major sound upgrade, super easy to install. I bit the bullet and went with the "Graphene Sluggo". Sound is simply amazing. Huge difference in soundstage and imaging.

swiss digital fuse box.

With 3 (so far) swiss digital fuse boxes used to power my Decware Torii Jr. amp, Decware CSP3 preamp, and PS Audio power regenerator the sound is breathtaking. I've heard from several friends that it is the best sound they have heard.

Fantastic

I was not expecting much, since I already had two Purons in my system. I took the Purons out as was recommended and I was so wrong. The Subway and Main Stream are fantastic. Took away even more grunge, that I didn’t even know was there until it was gone. I’m hearing so much detail that was buried far in the mix of so many songs, that I can’t stop playing music. Fantastic and amazing products.

Increased energy overall and bigger sound stage.

Love them. The improvement in the sound stage in width and depth is incredible! Definition and imaging is increased, The amps seem to be playing with much more energy. A real pleasure to listen to familiar music and hear the improvements. The SDFB's aren't leaving here!

SnubWay - Noise Defender
Christopher Porada (Winston-Salem, US)
A truly amazing device!

I was not expecting much, as my system is already very heavily tweaked with respect to noise elimination. Boy, was I in for a surprise. With just 24 hrs of settling in after plugging the SnubWay into my Torus RM20, my system now delivers that magical sound that normally only occurs during rare moments in the middle of the night, but now it sounds like that all day! This device is a real no-brainer, especially with VerFi's very generous return policy. Give it a try - I'd be willing to bet you'll keep it!

Mind blowing. The Graphene Sluggo and SDFB on my amp have added that little bit of magic I was looking for. Mark and the crew are great to work with. I ordered 2 more SDFBs and a Snubway after hearing for myself what Marks designs are capable of.
