REFERENCE Low Noise Power Supply

Reference Power Supply - Our lowest noise and best performing power supply to date

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.

From the large transformer and big smoothing capacitors chosen for their low ESR and ripple rejection to the precise vref 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.

With it in place the difference is profound. And I tried feeding the 5V PSU into a usb power line with USB being input source instead of spdif (and the other PSU feeding into the PC USB card) and it sounds incredible. I could never get on with the USB input but for the first time ever I love it. I'm revelling in detail.
