The Sbooster Vbus Isolator is a "no-brainer" tweak to upgrade your self-powered USB-DAC.
The Sbooster Vbus2 is the perfect addition to USB-tweaks like the UpTone Audio Regen. The Sbooster Vbus2 also improves the USB-chain when you have upgraded your DAC or SPDIF convertor with USB B power supply solutions like the Sbooster BOTWS USB B or the AQVOX USB PSU.
The Vbus isolator disables the polluted power from the host PC/streamer, therefor it only works with USB audio devices, that do not need power from the host PC or streamer to operate.
The Vbus2 is not compatible with following USB tweaks:
- Wyred 4 Sound Recovery USB reclocker
- Intona High Speed USB Isolator
So if DAC does not need the polluted PC-power to operate, then make sure to disconnect it.
