Astell&Kern AK PA10

The AK PA10 from Astell&Kern is a purely analog portable headphone amplifier. It features a Class A output stage as well as 3.5 mm and 4.4 mm inputs and outputs. With its analog circuitry, the AK PA10 delivers an exceptionally smooth, warm, and natural sound without the slightest distortion. To regulate the power supply, the AK PA10 has a switch that allows the Class A output current to be adjusted in three levels, tailored to your headphones or earphones. Additionally, the AK PA10 incorporates TERATON ALPHA sound technology, which generates sound quality that closely resembles the original sound through effective noise cancellation, efficient power management, and highly faithful amplification. Since headphones separate the left and right channels, this can lead to increased fatigue during prolonged listening compared to listening through speakers. Therefore, Astell&Kern has integrated a crossfeed function in the AK PA10. This mixes a portion of the signals from one channel and sends them with a slight delay to the opposite channel, creating a more centered and natural sound that resembles that of a speaker system, thus providing a particularly fatigue-free listening experience. Crossfeed is generated exclusively through hardware circuitry and not through software. This results in a refined, smooth crossfeed effect with an authentic sound that offers a lot of spatiality, liveliness, and ease. Crossfeed can be turned on and off as needed. The AK PA10 features a space-saving volume knob integrated into the housing, allowing for precise volume adjustments. The built-in battery provides approximately 12 hours of runtime on a single charge. With the portable AK PA10 headphone amplifier, you can enjoy an intense analog sound with plenty of power and spaciousness, keeping you immersed in music for hours without any fatigue.
