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) from 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 fine-tuned via a dedicated App, and paired with Bluetooth LDAC wireless transmission capability, it provides 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, to effectively suppress jitter during digital signal transmission. This significantly enhances audio stability and purity, delivering clearer, more accurate sound reproduction.
