[Limited Edition] W4-ACG

A model meticulously developed for modern times, allowing you to experience sounds you've never heard before.

■ The true essence of Luxury&Precision, uncompromised in a palm-sized device
The "W4-ACG" is a special edition model produced in a limited run of 499 units worldwide. It features a precision mirror-polished copper body housing the proprietary DAC LP5108 developed by Luxury&Precision. This model further refines the W4's low power consumption, low distortion, and high dynamic range, delivering a unique sound design that integrates flagship-grade fundamental performance with high shielding capabilities.

■ Another W4, optimized from the chip's core for the ACG sound most preferred by users.
The most significant feature of the W4-ACG is that, based on the highly acclaimed W4, known for its pure and natural sound, it has been completely re-engineered internally, beyond just software processing, to strongly emphasize compatibility with Anime, Comics, and Games (ACG) music. By strengthening the chip's signal transmission path through an increased PIN configuration and meticulously refining the register settings within the chip's deeper layers, it precisely reproduces the complex synthesized sounds and vocal textures characteristic of ACG audio with accurate phase.

■ Equipped with a dedicated tuning mode
The W4-ACG features a dedicated tuning mode, "STL ACG," optimized in conjunction with its hardware design.
While inheriting the sound design philosophy cultivated in the company's flagship DAP "LP6 Platinum," the chip settings and circuit adaptation have been meticulously adjusted specifically for the W4-ACG. By carefully refining everything from the attack and contour of sounds to the decay of their lingering echoes, it naturally brings out the vividness, delicate expressions, and spatial clarity of ACG music.

■ Output design that brings out the best in IEMs
To fully unleash the potential of low-impedance, high-sensitivity IEMs/wired earphones, a low-voltage, high-current-oriented output design has been adopted. By not applying excessive voltage and ensuring the necessary driving power and controllability, volume control is precise, and even faint, easily buried signals are not lost. The high-current output also contributes to tight bass, quick transients, and stable sound contours. This unit will be particularly compatible with users who want to drive CIEMs (in-ear monitors) and high-quality wired earphones delicately and stably.

■ Supports multi-stage configurations. Equipped with LO OUT mode to leverage DAC capabilities.
In addition to high decoding performance and low-distortion PO output, the W4-ACG features a dedicated LO output designed for combination with the company's portable amplifiers "EA4/EA4 Limited." Output parameters have been meticulously verified to avoid compromising gain balance and dynamic range when connected. By fine-tuning for optimal fixed voltage output, a natural and stable playback balance is achieved even when combined with the EA4 series. While achieving high completeness as a standalone unit, it also demonstrates high capability as a source device that can send signals to a portable amplifier when needed.

■ Beautiful exterior exuding a unique presence
Based on the design and processing expertise cultivated with the EA4 Limited, the exterior undergoes a precise polishing process. While bringing out the texture unique to mirror-finished copper, a titanium nitride coating is further applied to enhance surface hardness and scratch resistance, ensuring long-term use. This elevates it to a level of perfection befitting a special edition.

■ Exclusive case to protect the unit
An exclusive genuine leather case is included to protect the beautiful mirror-finished copper. The material used is cowhide with a distinctive bloom. It is vegetable-tanned leather with an Italian-style wax finish, which develops a deeper character with use. The interior of the case has an 8-layer structure and also supports magnetic attachment with N52 neodymium magnets. This prevents deformation and gently protects the mirror-finished housing.
