In 1973, the SP3 was hailed by every major critic as the best preamplifier available, and this tradition of excellence has continued ever since. The Reference Series from Audio Research was first introduced in 1995 and has been the ultimate representation of performance, musicality and dynamics.

In addition to six long-life 6H30 tubes in the gain stage, the enormous and highly-regulated power supply has another 6H30 with a 6550 providing vacuum-tube regulation.\u003cbr\u003e\u003cbr\u003eThe Reference 6SE replaces the Reference 6 and offers the highest performance ever available in a single-chassis preamplifier. Benefitting from the development that went into the Reference 160-series amplifiers, and the latest Reference 750SEL, the 6SE incorporates a myriad of new parts that have been judiciously incorporated into its design. The final 6SE would not have been possible without these revolutionary amplifiers.\u003cbr\u003e\u003cbr\u003eRegardless of the recording, the improvement in sound is immediate and compelling. Effortless, dynamic, and dimensional.
