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 an extremely qualitative material whose design aims at excellence.
