#21 SMSL DO100 Discontinued eBay
Pros: Audio Science Review measured a SINAD of 120 dB, so its noise and distortion are inaudible. It accepts USB, optical, coaxial and Bluetooth 5.0 with LDAC, aptX HD and AAC, and drives amps or powered speakers over RCA or balanced XLR. Its adjustable line output and remote let it control powered speakers directly without a preamp.
Cons: It is no longer sold new, so you will have to look for a used unit. There is no headphone output, so a separate amp is needed for headphones. Current models such as the SMSL D400ES earn the same rating with a slightly cleaner measurement and are still in stock.
