Originally introduced in 1995, the Reference Series from the legendary American firm Audio Research has represented the ultimate expression of the concepts of performance, musicality and dynamics applied to the reproduction of recorded music, with the Reference 6SE line preamplifier being the most important chapter. recent of this exciting story. Equipped with a single, very high-performance gain stage, the Reference 6SE uses a fully balanced, feedback-free design set to Class A. In addition to six very high-quality 6H30 valves in its gain stage, it incorporates a highly regulated power supply. combining a 6H30 and a 6550 tube. The Reference 6SE replaces the Reference 6 and offers the highest performance imaginable in a single chassis line preamplifier. A direct beneficiary of the exhaustive development process that enabled the refinement of the refined Reference 160 range amplifiers and the monumental Reference 750SEL mono power amp, the Reference 6SE incorporates a myriad of new components that allow it to showcase a unique combination of high-speed Extreme response and resolution on the one hand and a richness of musical textures as precise as it is captivating on the other.
