Thanks Mark for the clarification update. Still have some questions as to how do these relate to the use of Puron, Mainstream, Snubway and power conditioner? Are they replacement upgrades or additions? Also, how does the new fuse black box relate to the SDFB? Just trying to understand the ideal usage set up.
Question Thread - NEW Line Noise Black Hole and Snub Station Zero by Vera-Fi Audio
Here for questions on these two new products - CE and FCC Approved (all 16 parts) Multi Voltage - 85v ~ 240v 50/60Hz
Our Two New Solutions to worsening Power Grids.Everywhere - Maybe our most important products we've ever produced in our 6 years.
Line Noise Black Hole
Product Description
The Line Noise BlackHole (LNBH) is a compact, plug-and-play EMI/RFI sink filter designed to passively clean up noisy AC lines. No current limitation, no sonic compression—just quieter backgrounds and more revealing sound.
The Power Noise Problem
Power lines today carry more than voltage—they carry noise. Routers, chargers, appliances, and dimmers inject electromagnetic interference into the AC line. This affects the transparency, dynamics, and clarity of your audio system.
How the BlackHole Works
Unlike series filters that can choke current, the BlackHole connects in parallel to your circuit and absorbs high-frequency EMI/RFI through a 2-stage filtering network with:
- High differential and common mode attenuation
- Surge protection (8–15kA)
- Ultra-low leakage (<0.5mA)
It’s quiet, effective, and doesn't get in the way of your gear.
No Power Restriction, All Gain
Plug the LNBH into any unused wall or power strip outlet on the same circuit as your system. It cleans the entire line—without restricting current flow to your components.
Real-World Results You Can Hear
When installed correctly, it's designed to deliver:
- Lower background noise
- Sharper imaging
- Improved microdetail and texture
- A more natural, relaxed sound
It doesn’t color the sound. It clears the path.
Technical Specs and Safety
- Voltage Range: 85–230V AC / 10A
- Certifications: CE / FCC / RoHS / REACH
- Construction: IEC inlet + fused switch + NEMA outlet
- LED Indicator: Green glow confirms power is active
Safe for most HiFi systems, not suitable for medical equipment or high-leakage circuits.
Set It and Forget It
Once plugged in, the Line Noise BlackHole works silently in the background. Add more units across your home for cumulative noise reduction. It's the easiest upgrade you'll ever hear.
The Line Noise BlackHole is designed in the USA and assembled in China using only premium-quality components.
Snub Station Zero
Product Description
Snub Station Zero (SSZ) is an all-in-one mains power conditioner for audio/visual components that provides a state-of-the-art DC blocker, high-performance EMI filter, and an automatic soft start circuit that uses a solid state relay (SSR) to prevent large in-rush currents that can damage your equipment during the power-up phase.
Understanding In-Rush Current and Its Impact
The in-rush current spike inflicted on a toroidal transformer often used in high-end audio amplifiers can be up to 20x the nominal rated current, and this large current spike causes magnetostriction—or mechanical stretching in the copper windings every time it is powered up. This is the quickly dissipating buzz sound one often hears when switching on an amp containing a large linear transformer. Over time, this mechanical stress can cause the copper windings in the transformer to fail.
DC Blocker Benefits
The DC blocker uses four premium EPCOS 22,000uF capacitors with audio-grade discrete TO-220 rectifiers in series. These components are designed to handle and eliminate unwanted DC offset in the mains power, protecting your equipment from potential damage.
Custom EMI Filter for Noise Reduction
The custom EMI filter uses two large gauge copper wire CMC chokes and premium film capacitors to block unwanted EMI noise. This ensures cleaner power delivery, which enhances the performance of your audio/visual components by reducing interference.
Soft Start Circuit with Advanced Monitoring
The soft start circuit is unique in that it utilizes a precision Hall-effect current sensor to monitor, in real-time, the instantaneous current flow. When a significant change in current is detected, a solid state relay utilizing low on-resistance MOSFETs are employed to serve as non-contact solid state switches (which never wear out or arc, unlike mechanical relays) to bypass a pair of NTC (negative temperature coefficient) variable resistors that serve to slow down the in-rush current. Once the MOSFETs are engaged, the front panel 'SSR' LED glows to indicate that the SSZ is providing full current to the system.
Main Power and Additional Outlets
The main soft start circuit path can be used to filter a single device up to 10A of current. There are two additional NEMA outlet sockets that can provide power for smaller accessories that do not need the soft start feature but will benefit from the DC blocker and premium German-made Schaffner integrated EMI filter module.
Ideal Usage Scenarios
With three outlets total, the SSZ is ideal for powering a main power amp with the soft start outlet, a preamp and a DAC, etc. with the additional non-soft start outlets.
The SSZ is designed in the USA and assembled in China using only premium-quality components.
