Consider that your power is shared with fellow apartment-dwellers or houses sharing the same utility transformer. Every device in their home with an on/off switch sends spiky transients and noise through the system while spraying RFI around creating distortion. Air conditioners are prime culprits; lighting dimmers are distortion-producing machines, not to mention cheap wall-wart chargers greedily feeding only at the top and bottom of the 60Hz AC wave causing ripples of distortion when they all "bite" at once. Surges, phase distortion, over-and under-voltage conditions. imagine all that going on while they're trying to listen!
Bel Canto's current power supplies are praised for their low noise and instantaneous power delivery. Put that down to custom power supply rectification and filtering that vastly increases energy storage, lowering noise and reducing sensitivity to power line fluctuations. But since you always want to be in on the latest and greatest, Bel Canto is pushing the leading edge of eco-friendly, efficient power supplies with its newest development, the VBS1.
VBT? The Next Step In Pure Power Technology
Our Virtual Battery Technology is the next step forward in low-energy-profile, extremely low noise, ultra-efficient, integrated pure power supply designs, providing all the advantages of a 12 volt lead acid battery without the lead, the acid, or the battery for smoother, even-tempered, well-adjusted DC than previously available.
You techies will want to know that extreme isolation and tight regulation of 100 Joules of energy storage plus high current capacity provide unmatched transparency, dynamics, low frequencies gravitas, and even greater image palpability. You might also want to know the VBS1's power supply transformer is surrounded by common-mode and differential-mode filtering plus massive energy storage making for extremely quiet, well-regulated and isolated 12 volt DC power for the circuits to feed on. The VBS1 provides over 100dB of isolation and filtration starting below 100Hz up through the audio band and beyond into the RF region. For more, see Nuts and Bolts below!
The Nuts and Bolts
As mentioned, for the techies, the VBS1's power supply transformer is surrounded by common-mode and differential-mode filtering plus massive energy storage making for extremely quiet, well-regulated and isolated DC power for much improved sound. The VBS1 provides over 100 dB of isolation and filtration starting below 100Hz up through the audio band and beyond into the RF region. The result is up to 100 times lower noise than traditional linear supplies in the audio frequency band.
What's important to know is the Virtual Battery Supply powers up to three Bel Canto music products equipped with the 12 volt VB internal power supply board for an incredibly high-value upgrade path. These include the DAC3VB, PRE3VB or PHONO3VB, or any future Bel Canto product with VB 12VDC input compatibility. The VBS1 is designed to only power the Bel Canto e.One series as designated above and will not drive or connect to the power amplifiers
The Sound
Breathtaking results, a real and obvious overall improvement in sound that you can hear. You'll find greatly enhanced transparency, palpability, soundstage integrity, bass control, midrange texture, treble extension and sweetness.
