Really liking the Graphene Sluggos and the improved imaging and sound stage they present in my system.

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.

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.

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.

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!

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.

This improves upon my pretty decent Isotek power conditioner. I didn’t know the noise was there until it was gone.

Gorgeous !!!

An excellent product.
Highly recommended!

I first used it on my computer. I plugged it into a small power strip, which is plugged into the wall. another power conditioner/power srip is plugged into the same duplex. The picture on the monitor became slightly better, and easier on the eyes.
The sound is from a medium quality soundbar, and it too is more legible and a little less "tinny" sounding. Overall I like it. I will probably get another one for the opposite phase, which powers the main stereo system. This way both phases are equally conditioned, and should be great for the balanced step down transformer made by Richard Grey Power Company.

The Subway provides much darker backgrounds revealing more of everything

I got this subwoofer right off their site and am really impressed with the sound. I have it paired with two KEF bookshelf speakers and a Denon Home Theatre Receiver. Works super well in my setup.

I installed the MainStream at the beginning of my chain of two power strips feeding my router, modem and streaming source components. Results were fairly immediate and slightly more apparent over 2 to 3 days. There is a quieter background and more clarity to the music. This is one of my best bang for the dollar investments in my system.

With the installation of VBH my equipment is extremely stable which has broadened my soundstage and musical separation. One of most the cost effective tweaks I have tried along with their SnubWay filter. You can’t lose trying either product with their generous return policy and it is a pleasure dealing with Mark. Don’t take my word for it try them out for yourself
