Audio Research REF6SE Pre Amplifier - Silver

Here we have a high-end pre amplifier from American company Audio Research. The Reference 6SE is a purely analogue device with both balanced and unbalanced connections. Our example is in excellent condition with Sovtek valves fitted and comes with original factory packaging along with remote control, mains cable plus our standard three month warranty. Please note the fitted valves are from Sovtek and comprise; 6 x 1705; 1 x 1811; 1 x 1905.
Audio Research Say….
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 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. The Reference 6SE is the latest chapter in our story.
With a single gain stage, the 6SE is a fully-balanced, Class-A design with zero feedback. 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.
The 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.
Regardless of the recording, the improvement in sound is immediate and compelling. Effortless, dynamic, and dimensional. The speed and resolution merge with musical color and textures that are both accurate and captivating.
