Masterclass LA-4
The Sugden Masterclass LA-4 is a line level stereo pre-amplifier with authority, finesse and the capability to develop a sound stage with imaging, dimensional realism, and time/space elements in perfect harmony. The units primary function is ‘Simply More Music’ with a neutrality to allow end users to choose mating components and obtain customised performance.
The Sugden Masterclass LA-4 pre-amplifier was developed to complement the Sugden Masterclass Power Amplifiers and at its heart has dual mono, dc-coupled, Class A, current feed back gain stages. The gain stages are each powered by current shunt differential power supplies which enable the fastest transients and most powerful crescendos with true musical empathy.
The Sugden Masterclass LA-4 pre-amplifier has provision for stereo pairs of balanced inputs, four single ended RCA (phono) inputs, a By-Pass input, Input and output recording facility, two main pre-amp outputs and a balanced output.
Like all Sugden products, Sugden Masterclass LA-4 pre-amplifier is hand built by Sugden Audio in their factory in Heckmondwike in Yorkshire. This is as British as hifi gets, and we here at Fanthorpes are proud to support Patrick and his team.
