Product Description

Reference V2 QPG Power Supply

The Reference as been designed to offer the very lowest noise levels from a power supply. Pushing on the technology in our other psus we have managed to create something that works brilliantly with the very best audio equipment on the market. The Reference can be upgraded to Signature spec by purchasing our Vref module.

From the large transformer and big smoothing capacitors chosen for their low ESR and ripple rejection to the
multiple precise vref circuits, QPG technology and onto the ABT monitored low noise output this PSU really does stand head and shoulders above anything out in the market today in both design and performance. You wont find this level of quality PSU in anything manufactured at the high end of the audio market.

Please enquire about different voltages and connectors
