This constant SMSL churn of basically the same DACs every few months (maybe with a new chip, case or power supply) for just a bit better SNAD is getting old. One reason I went with the RME AD-2 FS Dac. Once you get into the $1000 SMSL/Topping range, they don't seem to offer much value. RME might not have the newest chips, but the features, quality and support is very impressive. And just a few hundred $ more- it is , for me, the no-brainer choice.
I would only get or recommend a SMSL (or Topping) DAC at the max $100-200 range. But with the Wimi Pro Plus, I am not even sure I wouldn't just not get it today for a 2nd system and a JDS Atom 2 amp.
