The P2 MK2 Fully Balanced Amplifier is a Successor with Ultimate Authority in Headphone Amplification Fully Balanced Design with 4-Channel Ultra-low Distortion Precision Linear Feedback Circuit Built-in High-power, High-efficiency, Low-noise GaN Switching Power Supply 99 Low-noise Opamps Operating in a Parallel Design Three Switchable Gain Levels P2 MK2 Engineered to drive the most demanding headphones effortlessly, this fully balanced desktop amplifier delivers a staggering 14W of output power per channel at 16 ohms. At the core of its uncompromising acoustic performance is a revolutionary architecture featuring four ultra-low distortion Precision Linear Feedback Circuits (PLFC) and an astonishing array of 99 low-noise op-amps working in flawless parallel. This relentless pursuit of audio perfection yields a breathtakingly low distortion rate of just 0.00006% and a sprawling frequency response from 20Hz to 100kHz, ensuring that every transient, dynamic swing, and micro-detail is rendered with visceral impact and absolute fidelity. GaN Switching Power Supply Mastering such immense power requires extraordinary control and structural purity. The P2 MK2 achieves a pitch-black sonic background with an exceptional 135dB Signal-to-Noise Ratio, made possible by a cutting-edge, built-in Gallium Nitride (GaN) power supply and high-precision, low-temperature drift resistors. Optimized for Headphones and IEMs Whether you are listening through power-hungry over-ear flagships or highly sensitive In-Ear Monitors (IEMs), the specially optimized 3-gear gain control and custom-designed volume potentiometer guarantee perfect channel balance and a completely hiss-free experience. Comprehensive Connectivity Beyond its prowess as a world-class headphone amplifier, boasting comprehensive 4.4mm, 4-Pin XLR, and 6.35mm outputs, its dedicated pre-out function allows it to serve as a Hi-End pre-amplifier for your active speakers.
