Phoenix Gold ZQ9004

The ZQ9004 is a high-quality four-channel amplifier with a dual-power system and an excellent PCBA designed to optimize clean and efficient power supply to feed the amplifier's power stage.

This top-class audio setup was developed as a highly exclusive and valuable specialty product for audio electronics. Phoenix Gold is constantly working to meet and exceed the growing demands of audio enthusiasts around the world to offer them the ultimate listening experience.

The ZQ9004 was developed in the EU by Phoenix Gold's top amplifier master engineers, who have over twenty years of development experience in high-end amplification.

To bring this incredible new amplifier to life, we insisted on using the best possible components from around the world, such as transistors from ON Semiconductor, magnetic core transformers from EPCOS, as well as capacitors from companies such as ELNA, Rubycon, Wima, and Nichicon.

Often overlooked passive components, such as capacitors, may not be the center of attention, but are nevertheless an essential part of an amplifier that can exceed expectations and delight audio enthusiasts.
