Lexicon ZX–7 | RX-7 | GX-7 Power Amplifiers
Designed to power the finest home theater and music systems, Lexicon power amplifiers are engineered to perform under the most demanding conditions. They deliver tremendous dynamics along with smooth extended highs, open midrange and solid bass reproduction.
Lexicon amplifiers feature massive toroidal transformers, with ample power reserves capable of reproducing the most demanding soundtracks without compromising the details inherent in these recordings.
A requirement of high performance systems is the reproduction of subtle details and sonic nuances that bring recordings to life. These details create a much greater sense of involvement and bring the performance closer to the listener. Lexicon amplifiers are remarkably quiet and feature exceptionally high signal-to-noise ratios. Equally important, distortion is extraordinarily low, reproducing fine detail with the utmost clarity.

The ZX-7 & RX-7 feature true balanced topologies. This approach results in lower noise, lower distortion, and eliminates interference from external stray electronic fields. Music reproduction benefits from a cleaner soundstage and increased dynamics, while the presentation of subtle detail is improved appreciably due to the significantly lower noise floor. Designed for the enthusiast, Lexicon power amplifiers are the perfect complement to our award-winning Digital Controllers & Disc Transports, and are ideally suited to power the world’s finest listening systems.
