WiiM Mini streaming D/A preamplifier

Characteristically, the email from Kal Rubinson got straight to the point: “I have a WiiM Mini that I have played with, but I am not the right one to review this as I am not sufficiently interested in or knowledgeable about wireless streaming. It … can handle uncompressed PCM via its DACs.” “I’ll review it,” I replied, intrigued by a $99 D/A processor that can stream hi-rez audio via Wi-Fi and that also has an analog input so it can act as a preamplifier.
