The E7 Series: Forging a New Path
Releasing August 17, 2024
The E7 series, featuring the newly developed "LE OS" operating system specifically designed for audio playback and a proprietary interchangeable DAC module mechanism, now includes a limited edition model (499 units) that uses the AK4497. At its core is the legendary Velvet Sound AK4497 DAC chip, highly acclaimed yet now absent from the market. This ultimate DAC chip is implemented in a dual configuration to pursue unprecedented sound quality.
🔶Evolved Circuit Architecture
Through extensive research and development by our engineering team, the hidden potential of the AK4497 DAC has been unleashed. For the PREMIUM model, we select units that exceed nominal specifications in metrics such as S/N ratio and THD+N, maximizing their exceptional performance.
🔶Meticulous Detail and Next-Generation Structure
The module design, featuring the industry's largest exchangeable area, eliminates the headphone amplifier from its configuration and removes components such as jacks that could bottleneck sound quality or component performance. This allows for an optimized layout and wiring in a spacious area. The DAC analog section incorporates numerous independent power supply circuits to thoroughly reduce noise. Furthermore, capacitors have been added to each channel, and independent ± power supply circuits have been installed for each operational amplifier. Through seven major changes, including variable voltage supply settings, this innovative module has achieved the sound quality expected from LUXURY & PRECISION.
🔶FPGA Artistry
The E7 series introduces LP Tune, a new feature leveraging LP's unique FPGA. Users can switch between three sound tunings: "Low Distortion," "High Dynamic," and "Harmonic Tune" (PREMIUM only). These tunings are meticulously adjusted based on an understanding and respect for music as an art form. This innovation, along with DAC filters and lossless EQ, allows users to further explore their musical preferences.
🔶Wireless Connectivity
Equipped with Bluetooth receiver functionality. LUXURY & PRECISION's next-generation Bluetooth algorithm uses clock data generated by the FPGA as a generator, achieving optimized audio signals that sound so natural you'll forget it's a wireless input.
Supports high-quality Bluetooth codecs: APTX/APTXHD/APTXLL/AAC/SBC

※Please note that the PREMIUM/STANDARD models differ in features and specifications. Be careful to select the correct model.
※The E7 series does not support fast charging, so we recommend using the original USB cable and a standard charger with 5V output.
