OK, I don’t understand what’s going on here, and probably won’t hear back from this seller before the Nov. 11-17 discount event is over, but there seems to be a redesign of the Tempotec Sonata BHD being ninja-released by an unofficial store on Ali, with:
-
BAL and SE outputs (instead of just BAL)
-
“280 mW” max power, summed from both channels, in reality 140 mW per channel
[OK, you can disregard the rest of the hype below, if it’s half the advertised power per channel it’s actually nothing all that special] -
buttons for 16 volume levels (not clear if internal)
-
dedicated button for 3 gain levels
-
exceptional SNR (131) and THD+N (0.0004)
-
same price as the AkLIAM PD4 non-Plus, around 50 USD with all discounts

Man, just when I was about to spring for the AkLIAM PD4 (not the Plus because somewhat better THD, didn’t want to spend much, didn’t need the measly power increment, and was afraid of partial loss of EM protection via the big acrylic window in the metal housing) they pull this mysterious new Sonata out of their 4$$es. 
LE:
Yep, confirmed in DM by the official store, it’s their product. They planned to add it officially next week.
Aaand insta-ordered.
