The Musical Fidelity V-PSU is a very impressive, robust addition to the V-Series of compact audiophile components. It is a high performance, choke regulated external power supply that will power up to three V-Series components. The V-PSU makes notable improvements to the sonic performance of the V-DAC digital-to-analog converter, V-CAN headphone amp, and V-LP phono preamp. Inside the sleek compact housing of the V-PSU lies a sophisticated DC power supply. The ultra compact high µ core transformer has very low hysteresis. The V-PSU has three completely separate power supplies, each with its own dedicated transformer winding, for powering up to three V-Series components. As a result, crosstalk between PSUs is virtually zero. Musical Fidelity has taken care of every detail so that the B+ from the V-PSU is very high quality. The low ESR high capacity power supply caps are complemented by milspec 'blue' PTCs. The whole system is tuned for optimally matched output impedance and power supply current capacity. In short the V-PSU gives a real sonic boost to any of the Musical Fidelity V-Series products. You don't know what you're missing until you try one, and you won't believe the sonic heights that V-Series components can reach with the V-PSU.
