The Reference 6 is Audio Research's finest single chassis line stage preamplifier for good reason. Utilizing circuit and power supply elements derived from their two-chassis flagship, the REF6 squeezes as much quality and technology into a single chassis component as possible.

Almost since the inception of the brand, Audio Research has produced some of the finest components for music reproduction; this is especially true with regard to preamplifiers. In 1973, the SP3 was hailed 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 power. The Reference 6 is the latest chapter of the story.

The Reference 6 is not simply a market-driven product, but rather, a solution to a need which arose after the creation of the Reference SE Series amplifiers. Both preamplifiers of the Reference Series need the ability to provide the full benefit of this new sonic landscape. Increasing the tube count to six in the analog section, and advancements in the power supply improved both macro- and microdynamics and lowered distortion.
