The GCHA is a high-end headphone amplifier designed for audiophile listening. It is based on PS Audio's unique Gain Cell Technology.
The GCHA contains a Gain Cell's preamplifier stage and a Class A biased output stage. The GCHA can accept audio signals from any analog source or digital audio from your USB-compliant computer.
A unique feature of the GCHA is the volume control itself: which does not attenuate the audio signal in the tradional manner, rather, the level of the GCHA is adjusted by controling the gain of amplifiers inside the GCHA.
In a traditional headphone amplifier, an audio signal is presented to the amplifier at full signal level. The headphone amplifier then attenuates, or reduces, that input signal to reach the desired listening level with headphones. While this conventional method of controlling the volume is an acceptable practice, it does have drawbacks: the attenuators cause degradation of the audio signal. The GCHA solves this problem by use of the PS Gain Cell technology. Gain Cells have adjustable gain and need no attenuation of the input signal to achieve desired listening levels. Instead, the front panel volume control is a gain adjustment, rather than an attenuator. The removal of any attenuators in the signal path has a sonic advantage over conventional technologies.
You should expect unrivaled sonic qualities, with low noise, high performance audio being delivered to your headphones.
