Regarding direct comparison between SR Master Fuse & SDFB, I posted this last year.
I’ve tried Orange, Purple & Master Fuses from a well known company. I’ve been a fan of this company’s products because it has been my experience that most of them do deliver on their promise.
For me, to my ears, in my system & despite my unwavering optimism, exotic fuses like these have not been decent perfomance vs price upgrades. Only the Master fuse provided a discernible change to the SQ, but not nearly enough to justify the expense.
Yes, I could’ve returned these fuses before the generous return policy expired, but I was hopeful, that with time, each one would have a positive impact. The Purples will remain in several power supplies, but sadly, I will be reselling the gently used Master Fuse for significantly less than what I paid for it.
Meantime, I discovered several products being offered by Verafiaudio including the highly regarded plug-in mains filter Puron, of which, I have a total of 4. One pair is plugged into a quad wall receptacle & the other 2 reside in the first pair of receptacles of a Powercell 8SE made by the same well known company behind the exotic fuses I tried. The addition of the Purons made further improvements to the the overall noise floor while adding body, resolution, separation & depth to the soundstage.
Enter the Swiss Digital Fuse Box! This is a simple, easy to install, professionally calibrated breaker that allows each component to operate at its full potential. Simply put, you have to try this affordable device that punches well above its cost. My ability to describe the game changing improvements does not begin to capture the newfound enjoyment I have listening to my favorite tracks for hours on end.
Recently, I read in a forum someone’s description of depth as the ability to see & feel the other side of each note of music. That resonated with me as I struggle to describe the incredible dynamics the Swiss Digital Fuse Box unlocked & revealed.
All I can say is don’t knock it until you’ve tried it, but by all means, try it & experience the difference it will make in your system.
Oh, by the way, Mark & Lynn provide superb customer service!
PS- You have a choice of several different sluggos depending on your preference. Also, if you don't have an available power cord to go between wall socket or distributor, the upgraded piggy tail is high quality.
