The Solo started life in 2001 and has seen a decade of continuous improvement, and on its way What Hi-Fi? gave it five stars, warning customers to "be prepared to buy it there and then", if they dared audition it.
The Solo Studio Reference "Green" Mk.II — SRGII for short, is the result of 10 years of innovative headphone amplifier development.
The Green power supply described on our product pages for use with our budget stages or as entry level option for our flagship products, is a switched mode technology plug-top design.
It complies with EU Eco-design requirements on external power supplies (EPS), as well as many other carbon reduction laws around the world, including Californian CEC. It also complies with safety laws including UL, cUL and CCC.
The power supply itself does not contribute any audio properties - it is the modifications made to our range of products that has made it possible to successfully use low carbon switched-mode power.
Our investigations, which started in 2006, into making highly sensitive audio circuits successfully work on switched-mode power have led to a greater understanding on how to obtain a great sound from our phono stage preamps and headphone amplifiers. Even our highly sensitive moving coil phono stage preamps, the Gram Amp 2 Fanfare, the Reflex and the Revelation C, and the Elevator EXP flat gain moving coil step-up amplifier work without problem and deliver the sort of performance the Graham Slee name is famous for.
The Green power supply is self adjusting to mains voltages around the world and supplied with the appropriate plug-head to fit UK, European, Australian or US power outlets.
Its efficiency is due to it operating at an ultrasonic frequency instead of the mains frequency. This means it can use a tiny transformer for a similar amount of power as a much larger conventional transformer.
The Green power supply along with some of our earlier linear plug-top power supplies are the only products in our range not manufactured by us.
