TOPPING E50 Balanced DAC ES9068AS XMOS XU216 MQA 32bit 768kH

Audio science review:
Conclusions
What can I say but another star performance from Topping. Company is so focused on squeezing every bit of noise and distortion out of these products while providing them to us at bargain prices. And in this case, great looks as well. I wish I could complain about something but nothing comes to mind.

Another exemplary performance from Topping, landing it almost at top of all DACs ever tested.
Noise performance is excellent as well.
Linearity is as perfect as you can get.
IMD performance is excellent.
Multitone performance is superb with almost no frequency dependency.
Jitter over USB is perfect.


Topping offers with its E50 a compact and very powerful DAC, using proven audio components widely recognized by audiophiles.

This one is indeed based on an ESS ES9068AS digital/analog conversion chip as well as an XMOS XU216 USB interface, allowing it to read high resolution files but also to decode MQA files.

It also benefits from a balanced output on TRS connectors.

ESS ES9068ASDAC
The E50's digital-to-analog conversion stage uses the latest ESS ES9068AS DAC chip to deliver a transparent and richly detailed sound. The device ensures excellent performance with a very low distortion of 0.00009% or a dynamic range of 126dB.

USB XMOS XU216
The USB interface of the Topping E50 uses a second generation XMOS XU216 16-core chip with custom Thesycon driver. Associated with the ES9068AS DAC, this combination allows a perfect sound neutrality but also the support of high resolution files, up to PCM 32bit 768kHz, DSD512 and MQA. The USB input also uses a CPLD to process the clock signal and thus considerably reduce the jitter level.


Full connectivity & Balanced output
Topping's DAC benefits from a complete connectivity to adapt to all types of audio systems. We can find USB-B, Optical Toslink and Coaxial as inputs. On the output side, the E50 offers both single-ended RCA and a double 6.35mm TRS jack for balanced output.


Power supply & Auto ON/OFF
The Topping E50 is powered by 5VDC, either via its DC jack connector or directly on its USB-B input. It also benefits from an automatic on/off function. Thus, if the E50 receives a signal, it turns on automatically. In the same way, if it does not receive any signal on the selected input during 1 minute, then the E50 turns off.

Pre amplifier function
The E50 has a preamplifier function. It is thus possible to control the volume level thanks to the remote control supplied. Ideal for association with a power amplifier or active speakers.
