The Topping D50s is the direct evolution of the D50, a proven DAC that is particularly appreciated by many customers and audiophiles. While this new model is largely based on the design and architecture of its little brother, the main evolution is in connectivity since the D50s now offers Bluetooth support. The device can now also be controlled via remote control and its audio performance has been revised upwards.

For the rest, we find all the tip components of the previous version such as two ESS ES9038Q2M conversion chips, a latest generation USB interface module XMOS U208 or OP1612 operating amplifiers, all integrated in a beautiful and robust aluminum housing. Topping once again offers us an extremely qualitative material whose design aims at excellence.

Double ES9038Q2M

The D50s is one of the best components on the market for high quality rendering and an advanced audio experience. Thus, the core of the device is composed of two ESS ES9038Q2M conversion chips operating in parallel so that all channels benefit from a detailed signal and are processed with precision. In addition, these chips, combined with the other components of the device, allow the D50s to support high sampling rates up to PCM 32bit 768kHz, DSD512 and DoP64.

High Performances TI OPA1612 SoundPlus and LME49720 OPA

The D50s is also equipped with two OPA1612 SoundPlus operating amplifiers and a TI LME49720, forming the device's low-pass filter. These PDOs offer excellent performance and ensure lossless signal transmission. The LME49720 operational amplifier is mounted on a DIP8 bracket and can therefore be changed to modify the sound of the device.

Auto On/Off Feature

A practical feature, the D50s is able to switch on and off automatically depending on whether or not it receives a valid signal. Of course, this feature can still be disabled in the device menus. Similarly, the display of the device can be set to turn off after 30 seconds without any action taken, to avoid the visual discomfort that can result from an on screen. The brightness of the screen can also be adjusted.

Easy to use

The D50s has two unique buttons on its front panel to control all the camera's features. The first is a simple button, the second is a 4-way joystick. The device is also delivered with an infrared remote control, allowing remote control.

Complete connectivity

On the connector side, the D50s from Topping offers a complete panel to adapt to the vast majority of uses. It includes Coaxial, Optical, USB and a connector to improve Bluetooth signal reception. At the output the device has a stereo RCA connection.

DAC + Preamplifier function

The D50s is therefore a DAC but also offers an adjustable volume. It can therefore operate as a DAC combo + preamplifier and be directly connected to an amplifier or active speakers.

OTG Compatibility

The Topping D50s supports the OTG standard. It is therefore possible to connect a compatible smartphone or Android tablet to it to send your audio files directly. For iOS devices, it is necessary to use the Camera Adapter Lightning to USB.
