XUELIN IHIFI960 Modify Version LM49990 16GB AMP portable HiFi Music Player
- Good sound Quality just getting better! Factory Modified LM49990 Ultra-low Distortion, Ultra-low Noise Operational Amplifier chips.
- This op amp LM49990 chip to replace the original lpf friction machine tone has improved significantly, with immediate effect. More specific performance:1.A larger sound field 2.Sweeter vocals, more clean sound, and reduce burr sense 3.More musical mids and more controled bass
- The only drawback we found is the battery life. It reduces to around 7 hours per charge when playing lossless music.
- Ihifi960 is based on ihifi812 from years of research and development .This equipment had joined the rare coaxial / optical fiber output (optical fiber connection can achieve electrical isolation to prevent digital noise transmitted through the ground, so that the signal is more pure), the product can not only carry, more cross-border acts as a pure digital turntable / desktop CD role, providing high-quality end-to-end digital audio, not less than the effect of a high-end CD. Flexible file management is better than desktop CD. While it commendable remains 12 hours of battery life, while 30% smaller.
- Filtering use solid state capacitor and polymer capacitor combination, that make power purity reached a new height, making a foundation for the voice of details and reducing the background noise music.
- Pure sweet sound, dark background, has a simulation feel.
