#8 Gustard X18: $749.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 122 dB, so its noise and distortion are inaudible. It has nearly every input you could want, including USB, I2S over HDMI, AES/EBU, coaxial, optical and Bluetooth with LDAC and aptX HD. It feeds an amp or powered speakers through RCA or balanced XLR outputs, with a volume knob for direct control.
Cons: The Topping D70 Pro SABRE matches its rating and measured slightly cleaner for less, and the SMSL D-6S matches its rating for a fraction of the price. Its full width chassis takes up more desk space than compact DACs.
