A New Frontier: The Birth of the E7 Series

Releasing on August 17, 2024

Introducing the E7 Series, a groundbreaking line built around the newly developed audio-dedicated operating system LE OS and a proprietary modular DAC replacement system. This limited-edition run of 499 units features the legendary AK4497 DAC chip, a part once revered for its "Velvet Sound" but long absent from the market. Now revived in a dual-DAC configuration, the E7 aims to extract every drop of sonic potential from this iconic component.

🔶Circuit Architecture That Unlocks True Potential

After exhaustive R&D efforts, our engineering team has succeeded in unleashing the full capabilities of the AK4497 DAC. For the PREMIUM model, only the highest-performing units—those surpassing standard S/N ratio and THD+N specifications—are hand-selected, ensuring world-class audio performance.

🔶Precision Craftsmanship Meets Next-Generation Design

The E7 features the largest modular interface in industry history, made possible by eliminating the headphone amplifier from the main circuit path. By also removing signal-path bottlenecks such as traditional jack components, we’ve achieved an optimized internal layout with expansive real estate for high-performance routing.
Dedicated power supply circuits have been distributed throughout the analog DAC section to minimize noise. Enhancements include expanded channel capacitors, independently regulated ± power rails for each op-amp, and adaptive voltage supply modules. After seven major design revisions, this module now delivers sound reproduction that meets the exacting standards of Luxury & Precision.

🔶The Art of FPGA

Our in-house FPGA architecture introduces LP Tune, a newly implemented feature offering three distinctive tuning modes:

Low Distortion / High Dynamic / Harmonic Tune

Each tuning profile reflects a deep understanding and reverence for music as an art form, offering nuanced adjustments that allow listeners to shape their ideal soundscape. Combined with user-selectable DAC filters and lossless EQ, LP Tune empowers in-depth audio exploration like never before.

🔶Wireless Connectivity

Equipped with a Bluetooth receiver, the E7 incorporates next-gen Bluetooth algorithms developed by Luxury & Precision. By using FPGA-generated clock data as a timing generator, the incoming wireless signal is optimized for maximum fidelity—resulting in a natural, immersive listening experience that makes you forget you're even using Bluetooth.
Supports high-quality codecs: aptX / aptX HD / aptX LL / AAC / SBC

Note: The E7 Series does not support fast charging. Please use the included USB cable and a standard 5V charger for optimal charging performance.
