Measuring just 280 mm x 200 mm, the ZQ5004 can be easily concealed, or you can make it the highlight of the installation thanks to its high-quality black-and-gold finish.

Amplifiers in the ZQ series feature award-winning technology that not only delivers a natural, uncompromising sound but also embodies the past, present, and future of Phoenix Gold in its design. The ZQ series is equally popular with PG enthusiasts and audiophiles alike, representing a rebirth of PG's original core values and offering first-class high-end technology that brings the purest sound to the masses.

The ZQ5004's gold-plated circuit boards feature a unique dual-layer gold immersion treatment, along with 24-karat gold-plated terminals that provide excellent connectivity. The dual power supply has been optimized to competently power the amplifier, and only the best capacitors from Nichicon (Japan) and Wima (Germany) are used to ensure the best possible uninterrupted power supply.

High-end polymer gain potentiometers are used to support the amplification, while the shielded transformer cores, manufactured in Germany, ensure a pure power supply to the amplifier. The two-tone extruded heatsink with optimized heat transfer ensures that the amplifier remains cool even under the highest and most demanding loads.
