Topping E50 USB DAC ES9068AS XU216 Hi-Res Decoder

ES9068AS DAC Chip.
The E50 uses the latest ESS ES9068AS DAC chip, a 32-bit, 2-channel D/A converter designed for audiophile-grade applications. Using the critically acclaimed ESS patented HyperStream II architecture, QUAD DAC technology, Time Domain Jitter Eliminator, and advanced SABRE HiFi technology, the ES9068AS delivers world-class audio performance.

DSD512 & 32-bit/768kHz PCM via USB.
The E50 offers top-of-the-line decoding via USB with the XMOS XU216 2nd generation 16-core processor. It supports 32-bit/768kHz PCM, DSD512 native, and MQA full decoding. Windows 10, Max, Linux, iOS, and Android users can plug-and-play the E50 without installing drivers.

24-bit Coax and Optical.
Get HiFi decoding not only with the USB input but with the coax and optical as well. The E50’s coax and optical inputs support 24-bit/192kHz PCM, DSD64 (DoP), and MQA rendering.

Ultra-Portable 5V Power Supply.
The E50 requires only a 5V power supply, meaning you can power it with the USB port of your PC or Mac, or a portable phone charger. At only six inches on its longest side, you can slip it into your suitcase, backpack, or briefcase and use it on trips.

Smart On / Off.
With an auto on/off function for all inputs, the E50 is a true “set it and forget it” DAC. It automatically turns on and decodes whichever input is receiving a signal, and when it hasn’t received a signal for sixty seconds, it automatically turns off.

Selectable Output Port.
The E50 features an output selection button with options for “TRS only,” “RCA only,” and “TRS + RCA.” This last option lets you run cables to two different destinations, such as a headphone amp and powered monitors, and listen to either without having to do the cable shuffle.
