About the X350.5
The Pass Labs X350.5 is a Class AB stereo power amplifier designed to deliver high-quality audio with a robust power supply. It is capable of producing 350 watts per channel into 8 ohms and 700 watts into 4 ohms, making it suitable for a wide range of speaker systems. The amplifier is heavily biased into Class A operation up to 40 watts per channel, which contributes to its smooth and nuanced sound. It features a voltage gain of 26 dB, input impedance of 30 kohm (single-ended) and 20 kohm (balanced), and a damping factor of 150 (though some sources list it as 250). The X350.5 is praised for its ability to present music in a non-fatiguing, low-noise manner without the 'buttery' sound often associated with some solid-state Class A amplifiers. It is visually striking and built with high-quality components.
