Lexicon ZX-7 — The Conductor of Power

In the sanctum of sound, the Lexicon ZX-7 stands as a monumental force — a seven-channel amplifier that wields authority with finesse. Each channel pulses with 300 watts into 8 ohms (450 watts into 4 ohms), yet the performance never screams — it sings. With fully balanced, symmetrical circuitry, the ZX-7 listens like a ghost, transparent to the music’s soul, delivering nuance, depth, and dynamic impact in equal measure.

When a whisper is needed, it offers silence. When the tempest arrives, it responds with effortless poise. It commands orchestral swells, cinematic storms, and quiet acoustic passages alike, all the while preserving clarity, spatial scale, and tonal purity. With gold-plated binding posts, dual toroidal power supplies, and rugged build, it is as much a sculpture as it is a sonic engine — an amplifier built for those who demand that every channel sings, that every moment matters.
