The addition of the PSU1 instead of the “green” power supply makes for a lift in performance as well as a greater sense of scale and openness.

The PSU1 power supply circuit has a precisely optimised Kelvin-current ground return and therefore has superior regulation. This leads to an improvement in stereo precision. It also has a combination of reservoir capacitor types to give the best sound quality.

Please Note:

The Novo, Solo SRGII “green” and Voyager are sold complete with the switched mode power supply.

The Solo SRGII is also available complete with the PSU1 power supply instead of the “green”, and the Solo Ultra-Linear is only sold complete with the PSU1.
