#2 Topping D900: $1,799.00 Amazon eBay
Pros: Audio Science Review measured 122 dB SINAD, so its noise and distortion are transparent. It has a huge input set, including USB, two optical, two coaxial, AES, I2S and Bluetooth with LDAC and aptX Adaptive, plus a volume knob, 10 band parametric EQ and an XLR preamp output for powered speakers.
Cons: The Topping D50 III matches its rating with slightly higher measured SINAD for a small fraction of the price. Outputs are XLR only with no RCA, and at 2,520 g it is a large unit.
