Short answer: the SMSL D200. Both are rated 4.8/5 (#17 and #11 of 30 DACs), and the SMSL D200 costs $319 against $399 for the SMSL DO200 Pro, so with nothing between them on measured performance, price settles it.
The case for the SMSL D200: Audio Science Review measured a SINAD of 116 dB, so its noise and distortion are inaudible. The catch: The SMSL D-6S rates the same and measures cleaner at 122 dB for less.
Why pick the SMSL DO200 Pro: Audio Science Review measured 122 dB SINAD, so its noise and distortion are inaudible. The catch: It is a DAC only, so you need a separate headphone amp or powered speakers.

The Two Amps and DACs In Full
SMSL D200: $319.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 116 dB, so its noise and distortion are inaudible. It feeds powered speakers or an amp through RCA or balanced XLR outputs, and a volume knob and remote let it work as a preamp. Inputs cover USB, optical, coaxial and Bluetooth with LDAC, aptX HD and AAC.
Cons: The SMSL D-6S rates the same and measures cleaner at 122 dB for less. Its SINAD trails the 123 dB of the Topping D70 Pro SABRE, though both are well past the point of audibility. At 1,214 g, it is a full-size box.

SMSL DO200 Pro: $399.00 HiFiGo eBay
Pros: Audio Science Review measured 122 dB SINAD, so its noise and distortion are inaudible. Inputs include USB-C, HDMI ARC, optical, coaxial and Bluetooth with LDAC, aptX HD, aptX, AAC and SBC, which makes it easy to connect to a TV as well as a computer. It feeds amps or powered speakers through RCA or balanced XLR, with remote volume in variable mode, and costs less than the SMSL VMV D1se2 at the same rating.
Cons: It is a DAC only, so you need a separate headphone amp or powered speakers. The SMSL D-6S earns the same rating for even less if you do not need HDMI ARC. There is no I2S or AES input.
