TOPPING E70 Velvet｜High-Performance DAC Decoder with AK4499EX Flagship Chip

Born for Pure Sound Quality, Unlocking Every Detail of Music

The TOPPING E70 Velvet is a high-performance **DAC decoder**, featuring AKM's flagship **AK4499EX** DAC chip and **XMOS XU316** USB processor, supporting high-resolution audio formats up to DSD512 and PCM 768kHz. At its core, it is equipped with the latest QCC5125 **Bluetooth** chip, supporting **LDAC Bluetooth** transmission, allowing wireless audio to achieve Hi-Res quality. Furthermore, the E70 Velvet is not just a pure decoder; it also boasts a high-quality **preamp function**, capable of directly connecting to power amplifiers or active speakers.

Compared to most DACs that only offer basic decoding, the E70 Velvet, through its independent low-noise reference voltage power supply design and preamp amplification function, provides a cleaner sound background and more flexible system compatibility. Whether for traditional Hi-Fi systems or modern PC-Fi desktop audio, it can serve as the central audio hub for your system.
