The Stack Audio VOLT is an audiophile linear power supply that provides an upgrade in performance for the Roon Nucleus/Nucleus+.  It replaces the standard external DC adaptor.

The audible benefit of a pure, smooth power supply has governed every aspect of the VOLT’s development, from component selection and electrical design to eliminating physical vibrations.

Switch-mode type power supplies can produce high frequency noise that can washback and affect the performance of other components in a hi-fi system. In addition, any computer-based system used as a server can generate electrical noise that can leak onto the mains supply and affect other components in the hi-fi system. The VOLT both replaces a switch-mode power supply and filters other mains induced noise two ways (in and out) for a cleaner sound.

The VOLT is a linear design built specifically for high quality audio systems that benefit from smooth, clean, DC supply. The result is tangible, with subtle details and nuances revealed in your music for a more engaging experience.
