TOPPING E50II｜High-Resolution DAC with AK4497S Chip

A Precise Digital-to-Analog Converter Built for Desktop Hi-Fi Systems

The TOPPING E50II is a high-resolution Digital-to-Analog Converter (DAC) launched by TOPPING, featuring AKM's flagship AK4497S VELVET SOUND™ decoding chip. Through the XMOS XU316 USB processor, it supports native audio specifications up to 32-bit/768kHz PCM and DSD512. Its built-in 10-band PEQ parametric equalizer function can be finely tuned via a dedicated App, combined with Bluetooth LDAC wireless transmission capability, providing ultimate sound quality and flexible control for your audio system.

Compared to typical built-in sound cards or previous generation products, the E50II utilizes an ultra-low jitter processing circuit with FPGA + PLL TopSync, combined with JitterNull technology. This effectively suppresses jitter during digital signal transmission, significantly enhancing audio stability and purity, resulting in clearer and more accurate sound reproduction.
