Bel Canto’s e.One Virtual Battery Supply (VBS) technology combines low noise switching technology, multiple stages of isolation, filtration and regulation to create a highly stable low noise power base for the VB front end audio components. The VBS1 supplies power for up to 3 front end VB designated components providing the cleanest power possible. The compact, heavy gauge, all-steel chassis provides additional isolation establishing an ultra low noise power foundation for building the ultimate audio playback system that brings music to life with extraordinary nuance and power.
-
Low Noise Switch Mode Power Supply (SMPS) provides over 90% energy efficiency, specific control over operating parameters of the supply, and high levels of isolation with significantly lower audio band noise than traditional 50/60 Hertz transformer based linear supplies
-
Extensive input filtration, low noise rectification and high energy storage prior to the SMPS
-
Massive bank of LC filtration using compound inductors, parallel electrolytic capacitors and final stage polypropylene capacitors to ensure hundreds of amperes of peak current capability and low noise across a wide frequency spectrum
-
1⁄2 of a Farad of total capacitance (500,000 microfarads) and over 100 Joules of energy storage 10X to 100X lower noise floor than traditional linear power supply
-
Provides over 100 dB of isolation starting below 100 Hz
-
Compact SMPS isolation transformer for superior isolation from the power line
The greatest reduction in noise occurs in the lower region of the audio frequency band in the critical midrange where the ear is most sensitive to noise and has the greatest impact on micro dynamics that lets you experience the subtle changes in timbre and a deeper more powerful bass. Reducing noise from the power line is critical to the overall performance of your audio. Eliminating the negative effects will allow your equipment to function at its optimal level.
Combining low noise switching technology, multiple stages of isolation, filtration and regulation, the VBS1 provides a highly stable, isolated and low noise base for precision digital and analog audio circuitry.
The VBS1 is designed to provide the ideal power source for up to 3 VB equipped products (DAC3VB, PRe3VB, CD2, Phono3VB, etc).
Bel Canto VBS1 Virtual Battery Supply Reviews

Can it get better than this? No doubt, no doubt. But, given a well-recorded and engineered CD, I don't believe I've ever heard any stereo, anywhere, that's impressed me more.
Inevitably I've begun to get used to this level of sound quality, though every so often I am still astonished. I suspect that, if there were a way to conveniently step back to the pre-VBS1 DAC3, I'd be pretty shocked at the change.
It seems there's really a lot more music on a CD than we're generally able or used to retrieving ... as I've played additional CDs from my collection, I've been astonished (yes, that's the word) at how real the music seems sometimes. Recordings I'm totally familiar with stop me in my tracks.
You might call the Bel Canto VBS1/DAC3VB a sort of truth machine. You get more of what's really on the CD. So that I've said a number of times, “It's as if I've never really heard this before.”
With the Bel Canto Virtual Battery Supply powering their DAC, the idea of accuracy has taken on a new meaning. A truth machine indeed.
