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.
