Superb for the price

Great service from Rapallo in current environment and shipped very quickly. I will certainly buy from this site again. I purchased this for a second system and I also wanted to try MQA on the cheap. Build quality seems great, looks awesome and has all the features I needed. It went in a system with a Raspberry Pi 4, 2021 Rega Brio and KEF Q350's. Very pleasantly surprised over the original Topping D10 I was using for Qobuz. To my ear this is extremely good value and will compare other Topping models should my main DAC ever need replacement.

Fantastic DAC

I was tossing up between this and the D10 Balanced, another well measured DAC by topping. But fate decided when the D10 was out of stock. Have this paired up with a SMSL SP200 for now, I have my eye on the L50. I've been running my amp of a little audioengine D1, unbalanced, and the difference is night and day, I was pleasantly surprised at the increased in volume and clarity.

Topping E50 Desktop USB DAC

The Topping E50 Desktop USB DAC uses the latest high performance DAC chip ES9068AS. With our excellence in design and engineering, it provides realistic and transparent sound quality.

  • Hi-Res Audio
  • DSD512 Native & DSD256 DoP & PCM768kHz
  • XMOS XU216
  • THD+N 0.00009%
  • MQA decode for USB, Coaxial and Optical inputs
  • RCA & TRS output
  • Ultra low noise preamp

USB supports DSD512 & PCM768kHz high resolution audio
USB input of E50 has a wide range of compatibility: Windows 10, MAC, Linux, IOS, Android can be plug and play. Only for Windows ASIO applications, you need to install the driver and set it up.

USB input has the best performance of E50. It uses XMOS 2nd 16-core processor XU216, which brings the support of 32bit 768kHz PCM, DSD512 native high-resolution audio and MQA full decoding. Even in ASIO application, we have customised Thesyon driver for Win10. (The sampling rate supported by different OS may vary due to the OS itself).

Coaxial and Optical (Toslink) also has good performance
On the E50, the traditional optical and coaxial input not only supports 24bit 192kHz PCM, but also supports Dop DSD64 and MQA rendering.

Ultra low jitter for USB inputs jitter is no longer anxious
Using CPLD to process the clock and greatly optimise the digital signal, achieved incredible jitter suppression capabilities. The use of new technology makes the femtosecond crystal and external clock no longer needed to supress jitter.

5V power supply anytime and anywhere
E50 uses a DC5V power supply, which can be easily accessed almost everywhere. You can power it up by USB port of PC, mobile phone charger or even a power bank.

All inputs support Auto On/Off function
E50 auto On/Off function, it will automatically turn on and set to the input which the signal is valid. And when the signal of E50’s selection is not valid for 1 minute, E50 will turn off automatically.

Selectable output ports
E50 has full balanced TRS output and single ended RCA output. You can choose “TRS only”, “RCA only” or “TRS+RCA” output to meet different usages in the multiple systems.

Preamplifier function
E50 has preamplifier function so you can control the output volume on the remote control. This will provide great convenience when connected to a power amplifier or monitor speakers. And also help you leave the budget for a preamplifier.

L50 will be the best headphone amplifier for E50
L50 and E50 have fully matched design languages and styles, and signals can transmit in balanced by TRS. L50 is suitable for almost all kinds of headphones.
