Description
Special version of the Reference 75, the Audio Research Reference 75 SE is a reference stereo power stage whose starting point lies in the sensational SG150 power stage - pertaining to the US firm Galileo Series - and the powerful power valves Of last generation that incorporates, the KT150.
The exceptional musicality of the GS150 made it a lot of fans and critics from around the world to contact Audio Research to explore the possibility of incorporating the aforementioned KT150 valves into Reference Series models. Still, unhappy with the mere change of the output valves, Audio Research engineers also decided to incorporate substantial improvements - both in terms of active and passive components and circuits - in the Reference 75 in order to fully exploit the potential Advantages of the change made. As far as technical specifications are concerned, the Reference 75 SE shines in its own light in parameters such as frequency response, slew rate or time of its life, while its generous feeding system allows it to provide a High power output with a wide spectrum of loudspeakers. But it is in the sound quality where the improvements are truly dazzling: more purity and absence of grain, resolution, macrocontrastes and dynamic microcontrastes, separation between channels, instrument focus, coherence in amplitude and phase and weight, authority and control Of the response in significantly improved bass.
