Short answer: the SMSL DO200 MKII. Both are rated 4.8/5 (#12 and #6 of 30 DACs), and the SMSL DO200 MKII costs $398.65 against $599 for the Topping D70 Pro SABRE, with the ratings tied, the lower price decides it.
Why pick the SMSL DO200 MKII: Audio Science Review measured a SINAD of 121 dB, so its noise and distortion are inaudible. The catch: The SMSL D-6S matches its rating for about half the price, so the extra money mostly buys more inputs.
The case for the Topping D70 Pro SABRE: Audio Science Review measured a SINAD of 123 dB, among the cleanest results available, so its noise and distortion are inaudible. It supports aptX Adaptive Bluetooth, which the SMSL DO200 MKII lacks. The catch: The SMSL D-6S rates the same for far less, so the extra cost mostly buys inputs and features rather than audible gains.
Buy the SMSL DO200 MKII. Both are rated the same, and it costs $200.35 less than the Topping D70 Pro SABRE.

The Two Amps and DACs In Full
SMSL DO200 MKII: $398.65 Amazon eBay
Pros: Audio Science Review measured a SINAD of 121 dB, so its noise and distortion are inaudible. It accepts USB, optical, coaxial, AES/EBU, I2S and Bluetooth with LDAC, aptX HD and AAC, and feeds an amp or powered speakers over RCA or balanced XLR. It matches the rating of the Gustard X18 for much less.
Cons: The SMSL D-6S matches its rating for about half the price, so the extra money mostly buys more inputs. It has no headphone output, and at 1.2 kg in a wide chassis it needs real shelf space.

Topping D70 Pro SABRE: $599.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 123 dB, among the cleanest results available, so its noise and distortion are inaudible. It feeds powered speakers or an amp via RCA or balanced XLR, with a volume knob for direct control. Inputs include USB, optical, coaxial, AES and Bluetooth with LDAC, aptX Adaptive, aptX HD and AAC, and it costs less than the SMSL RAW Pro-DAC1 with the same SINAD.
Cons: The SMSL D-6S rates the same for far less, so the extra cost mostly buys inputs and features rather than audible gains. At 222 mm wide and 1,050 g, it needs a full-size spot on the desk or rack.
