HIFI Audiophile Headphone Amp Decoder Dual CS43198 DAC DSD256 32BIT 384KHz 490mW High Power Lossless Audio Amplifier 3way Output

KP2 features two CS43198 chips for its DAC decoding output. Widely adopted in flagship audio players, these chips, combined with our state - of - the - art circuit design, deliver an astonishing balanced output signal - to - noise ratio of 131dB. With a distortion rate as low as 0.000169% under a 300 - ohm load, the KP2's digital audio performance rivals that of top - tier flagship devices.

In the analog circuit segment, the KP2 is equipped with two ESS9603 chips as independent audio amplification modules for its headphone amplifier. Boasting four - channel driving capabilities, it stands out with a unique design: two ultra - low - noise power supply chips are dedicated to driving two amplification chips (a departure from the common single - power - chip - to - two - amplification - chips design). This setup enables excellent high - power, low - distortion performance. When the 32 - ohm balanced port operates at 400mW, the distortion value is well below 0.001%. Additionally, the KP2 offers a switchable amplification mode, allowing users to freely turn on or off the independent operational amplifier system.

The KP2's motherboard features a military - grade, four - layer gold - plated design with an exquisitely laid - out audio circuit. It comes with a 12 - channel power supply system, where each of the 12 ultra - low - noise chips plays a crucial role in maximizing chip potential. Precise power control is the cornerstone of superior audio quality, and the KP2 excels in this regard.

The KP2 supports high - resolution audio formats up to 32bit/384kHz and DSD256. Despite its compact size, it can faithfully reproduce sound, enabling users to capture every sonic detail and uncover the stories behind musical compositions.

To ensure a pristine audio background, the KP2 incorporates high - performance filtering components at the data transmission source. These components effectively suppress high - frequency interference during USB transmission, delivering a cleaner audio experience.

Fitting three headphone jacks into a limited space was no easy feat. Through painstaking efforts and continuous layout optimization, our engineers have made the three - port output a standard feature of the KP2, setting a new benchmark for flagship audio devices.

The KP2 has a dedicated Type - C interface on its side. This interface not only provides independent power supply for the device, allowing connection to a power bank or mobile charger to relieve concerns about fast - draining phone batteries but also enhances audio control. It significantly improves gain for fast - paced, large - dynamic audio.

With 128 - level hardware volume adjustment, the KP2 offers extremely smooth and fine - grained volume control.

The KP2 provides multiple digital filtering sound tuning options, including the classic NOS (Non - Oversampling) mode, catering to different audio preferences.

The KP2 is compatible with headphones of various sensitivities and impedances. By pressing and holding the volume up and down keys for more than one second, users can cycle through low - power, standard, and full - power modes.

Crafted from aviation aluminum alloy through precision cutting, every production process of the KP2 is strictly monitored with micron - level precision. The result is a device that combines aesthetics with portability, making it an ideal companion for audiophiles on the go.

The KP2 comes with an eight - strand, super - thick silver - plated woven cable from Seiko. Each strand has a diameter of 1mm, ensuring top - notch audio signal transmission. The cable not only performs superbly but also exudes elegance and durability.
