TOPPING E50II｜High-Resolution DAC with AK4497S Chip
Precise Digital-to-Analog Converter 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. With 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 precisely adjusted via the dedicated App, and combined with Bluetooth LDAC wireless transmission support, 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. This effectively suppresses jitter in digital signal transmission, significantly enhancing audio stability and purity, resulting in clearer and more accurate sound reproduction.
