🔲 Fusing the convenience of a smartphone with the essence of a music player
New color of MagSafe-compatible DAC AMP "A100"🔲

NiPO began developing the A100 to meet the needs of sound quality-focused users of DAP products who seek smartphone-like convenience and operability, and to address the challenges of noise, sound quality, power consumption, and driving power faced by users of dongle-style DACs. The A100 allows for easy stacking and achieves sound comparable to high-grade DAPs.

This model is an integrated device specially designed to transform a smartphone into a serious music player. *A100 in Black/Blue/Orange available here

Addressing smartphone-induced impairments that degrade original audio

Based on NiPO's design philosophy, we have researched and adopted ideal elements from every angle to address harmful radio waves from communication antennas and variations in USB digital audio output quality. These elements include USB isolation, signal digitizing waveform shaping chips, and ultra-low phase noise clocks, all optimized for smartphone integration.
Furthermore, the architecture, which incorporates a low internal resistance, high-capacity battery and our unique current circuit design to reduce power consumption, provides users with the same high quality as high-end DAPs.

CMMT Current Mirror I/V Conversion

Some of the unique architecture used in our flagship model N2 has been adopted. To prevent transmission loss of input signals, I/V conversion, LPF, and voltage amplification are integrated and processed for the shortest single-stage gain path. Over 200 transistor pairs are precisely matched to achieve high-precision signal conversion at a 0.001% level. By also achieving phase distortion of 0.00015% or less, even minute sounds are faithfully reproduced.

Low distortion and high linearity achieved using SGMicro's SGM8262 headphone amplifier.

An ultra-low output impedance of just 0.22Ω ensures pure signal transmission. This design maintains high linearity, low noise, and high output swing even with low-impedance earphones, delivering exquisite sound across a wide range of products, from CIEMs to multi-driver earphones. Furthermore, with a maximum output of 525mW, the "Super-Linear" design provides clear sound not only for portable products but also for headphones.

USB Digital Isolation for Pristine Audio

Based on ADI's iCoupler® digital isolation technology, it effectively isolates strong electromagnetic interference from the connected circuit board. Following USB audio data signal integrity design, it achieves playback free from transmission errors and packet loss. High-speed data calibration, waveform shaping, and jitter suppression are performed internally through Accusilicon's AS318 series ultra-high precision femtosecond crystal oscillators, allowing you to experience unprecedentedly accurate and faithful playback with significantly reduced dependence on the performance of the source device. *UAC2.0

Equipped with ESS ES9039Q2M

Equipped with ESS's ES9039Q2M DAC, which is energy-efficient and excels in transparency and fine detail reproduction. Featuring 8 DAC filters and HyperStream IV architecture, it achieves low distortion, a wide dynamic range, and excellent noise immunity, delivering clear and high-resolution sound.

Reduced digital harshness, achieving high-resolution sound

By designing a circuit that independently supplies clean and stable power to nine systems, including digital and analog components such as internal clocks and amplifiers, individual optimization according to the load is achieved. This avoids interference across a wide band, improving soundstage clarity, localization accuracy, and achieving natural tonal quality.

Robust Power Design Supporting High-Quality Sound

The combination of a multi-stage LC filter, LDO, and ultra-low noise switching power supply suppresses power supply ripple noise by -60dB. By using a high-density lithium polymer battery with a low internal resistance of 20mΩ and selecting electronic components such as military-grade tantalum capacitors with ultra-low ESR, instantaneous high-frequency expression is also enhanced. By carefully selecting circuit components to achieve ideal characteristics, the background for music playback becomes even blacker, and even the most subtle sounds are delivered clearly.

Low internal resistance 3900mAh battery for comfort and high sound quality

Equipped with a switchable circuit that completely cuts off all current except for the audio signal transmission from the connected device. Internal drive is managed solely by the clean current from the unit itself. Despite its compact 131g body, it offers high transparency and excellent dynamic range. With up to 13 hours of continuous playback, it naturally reproduces the sharp sounds of string instruments and the delicate timbres of large ensembles.

Secure attachment for MagSafe compatible devices

The N52 NdFeB strong magnet provides a magnetic attraction force of over 2KGf, preventing it from falling off. As a high-quality audio device, the magnet is completely separated from the circuit by a dedicated shield, effectively eliminating and avoiding interference.

The included adhesive O-type and C-type magnet plates allow for comfortable attachment even to cases or devices that do not support magnetic attachment.

Sophisticated ash silver and black leather

The main body is made of full-grain leather, which features natural grain, often used in high-end brands. It has also cleared operating stability tests due to heat, and not only offers excellent durability and a luxurious feel but also allows you to enjoy the natural texture of the leather and the laser-engraved pattern chosen by popular vote, which deepens with use.

Includes only essential accessories to reduce environmental impact.

The included short charging/data cable maintains signal stability and features a highly requested flexible design. You can also charge the unit using the charging cable originally included with your smartphone.
