The TOPPING D90 is a new class of DAC being produced by TOPPING that uses the latest AKM D/A chip, the AK4499. It is also equipped with an XMOS XU208 USB chip, AK4118 S/PDIF receiver chip, and a CPLD programmable logic chip. For drivers, it uses German Thesycon drivers. Finally, it comes with a pair of AccuSilicon 451584MHz and 49.1520MHz high-end femtosecond clocks.

For inputs, the D90 has USB-B (XMOS), optical, coaxial, AES, IIS, and Bluetooth 5.0. For outputs, it has a single-ended RCA Stereo and a balanced XLR, which can be used one at a time or together simultaneously. The USB and IIS inputs support up to PCM32bit / 768 kHz and DSD512 Native. Optical, coaxial, and AES inputs support up to PCM24bit / 192 kHz. Finally, Bluetooth 5.0 input supports up to PCM24bit / 96 kHz LDAC.

It comes with a volume control function so it can be used both as a DAC and as a DAC/Pre-Amplifier. This volume control can be disabled to make the D90 function purely as a DAC that produces output levels of 4Vrms (XLR) and 2Vrms (RCA).
