In 1974 Zapco began a quest for perfect sonic reproduction. The Competition and Reference amplifiers became the benchmark serious listeners measured everything else against. Today's lineup pairs that Class A/B heritage with class-leading digital signal processing.
Class A/B selected-component high-end amplifiers — the best amplifier in its price range, full stop.
The amp that started it all, renewed — Class A/B and Class D with audiophile caps and op-amps.
The DSP-IV processors and amplified DSP — Zapco's modern digital signal-processing core.
Z-AP audiophile amplifiers — high-end internal components matched for pure sound quality.
ST-X SQ III — sound-quality amplification engineered for the serious competitor and daily listener alike.
ST-D Compact — full Zapco power in a dramatically smaller footprint.
ST-B Series — clean, capable amplification built on the Zapco foundation.
Capacitor banks and power supplies engineered to feed Zapco amplifiers without compromise.
Analog signal processors, line drivers and OEM integration — the connective tissue of a clean install.
