Outputs and power
Not stated: gain, supply voltage, SNR, distortion, crosstalk.
28.2mW@32Ω is stated in product gallery, image 5, without a socket; the SP7 has two headphone sockets (3.5 mm and Type-C), so the figure is not attached to either output.
The manufacturer lists a Type-C headphone socket (original: TYPE-C耳机接口) but does not say whether it outputs analog audio from the CX31993 or passes digital USB audio through.
