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.
