The FiiO Jade Audio GIGAS 1 is an extremely powerful, purely analog desktop headphone amplifier. It has been specifically designed to effortlessly and uncompromisingly drive even demanding over-ear models. Despite its power, the GIGAS 1 is remarkably compact. The name GIGAS is derived from the Greek word for giant and symbolically represents the amplifier's immense strength. Many over-ear headphones require a lot of power to fully unleash their sonic potential. With up to 4.6 watts of output power per channel in balanced mode, the GIGAS 1 plays your music with dynamism, precision, and maximum control. FiiO employs a classic audiophile combination in the GIGAS 1: a precise operational amplifier preamp paired with a discretely built Class AB transistor power amplification. The high-quality components ensure stable signal processing with minimal distortion, a wide soundstage, and tight, controlled bass. Operation is very straightforward and simple directly on the device. On the top, there is a large volume knob, and on the front, a switch for turning the device on and off as well as for adjusting the gain. The two gain levels allow for adaptation to different headphones. Power is supplied via USB-C, selectable at 5V when maximum output power is not needed, or at 12V PD when more power is required, especially at the balanced output. As the GIGAS 1 is a pure headphone amplifier, it can be flexibly connected to various devices: a small DAC, a portable music player, a CD player, a computer with a suitable audio output, or classic HiFi components. Thanks to its ultra-compact design, it saves valuable space on your desk or in your HiFi rack while delivering an extra boost of power to your headphones for a full and detailed sound.
