The Graphene is a worthwhile upgrade from the copper or brass SLUGGOs. I've got 3 and will order 2 more. Highly recommended!
These Piggy Tails are Excellent. You might think adding them to your favorite Power Cords (I use Rick Schultz Emersion), will be a little of a downgrade but, you will be gaining a HUGE BOOST in performance because of the Sluggos passing on that Sweet Power to your Electronics.
A Win Win all the way.
I had ordered 2 SDFB for my Amps. Due to some confusion, I received the wrong ones. I checked back with Mark and, I was instructed not to use them and to send them back. Vera-Fi will ALWAYS make sure that, you are using the correct Spec items. They took care of me all the way.
The SDFB Really adds that extra layer of Life to my System. There is Excitement when every I listen.
Good Company… they deliver
Let me start out by saying I'm not an audiophile, just an old guy who had the chance to buy some decent speakers. I shopped around watched hours of YouTube evaluations and made my choice. These are very solid speakers that look good anywhere.
As I said, I'm not audiophile but these things blew me away with the room filling sound from a compact size. I also added the Bluetooth amps so I can put them in any room by just plugging them in.
I would recommend these to anyone looking for great sound at a great price.
Fantastic: Mark is the Boss
It took a while to get them, but it was definitely worth the wait. For the price, these were way better sounding than I was expecting. Beautiful heavy wood cabinets, excellent range, tone and quality construction. I don’t think you’d need to, but a nice addition that I purchased was the Vanguard Caldera 12 inch subwoofer. It certainly complimented the system well. I didn’t want to spend a fortune and these fit the bill perfectly.
The customer service response was outstanding and prompt. I haven’t seen this level of personal customer attention in a long time. Highly recommend.
I have mine for a week or so; I have more on order, including the Snubway. But just this one unit has made an impact for the positive, so I am hoping to build on this. It is outlet d, and depending on which outlet it is plugged into, the results can vary, depending on the outlet position in the room. I put my in the Garage by the 1st AC outlet n to the fuse box after reading on that would be a good place for one unit, and they were right, right away the TV Sound bar and the 3 subwoofers connect sounded more dynamic, and the sound was more natural and with more body, what surprised me was on the 2nd level where my Stereo is it made a positive impact there also, I went down and unplugged it and went up and listened again and there was a drop off in presence, body and weight to the music as well as lacking the detail, piano is what I used with a stand up bass, to keep it simple, all sound more real with the one unit plugged into the outlet by the fuse box, so one is staying when I get the others I will built from there and see the extra ones impact, Mark is going to send me a package that he feels will work best for my system, Mark been great even took the time to call me to answer some questions on his products and which would be best for my needs. So try different outlets, let the unit burn-in for a week or so, the only time it hurt the sound was when I put it in the outlet before the Core balanced line conditioner; those two did not play nice together at all, lost mid-bass and bass, sound was thin, but that was the only time, I will try a Snubway there when I receive it. A good product, give it a try.
Really good uplift in soundstage, tonality and dynamics! No doubt about it or placebo!
The sound feels more pure!
At around 300 hrs like clarified by mark , the effect becomes very obvious!
I will probably go one for amp and one for streamer .
Bravo!
