Ground Zero GZUA 6SQ Amplifier
Ground Zero Audio 6-channel Sound Quality Amplifier
Description
The GZUA SQ series from Ground Zero’s elite Uranium lineup sets a new benchmark in amplifier performance for true sound quality purists. Available in 2-channel, 4-channel, and 6-channel configurations, these Class A/B amplifiers are engineered for stunning audio transparency, low distortion, and complete tonal control.
Featuring high-end WIMA® capacitors, OPA2134 op-amps, a bias-adjustable topology (from A/B to near-Class A), and wide-range high-/low-pass filters with bandpass capability, the GZUA SQ delivers breathtaking detail and musicality across the full frequency range—from a deep 10 Hz to 70 kHz.
Whether you're running a high-resolution 3-way front stage or bridging for clean subwoofer power, the GZUA SQ series offers incredible versatility, soundstage depth, and dynamic finesse. With 110 dB SNR, THD below 0.005%, and damping factors over 800, these amps are built to reveal the soul of your music—no matter the genre.
