Raspbi HAT ES9038Q2M / Ustars R38
found by chance this ES9038Q2M-HAT (38€, Aliexpress->LINK)..
interesting is that they use an “OPA1612” (i´ve just ordered one too, because i´ve often seen ES9038Q2M with this op-amp and will test them against the other op-amps i have here (Burson V5i-D, AD797, OPA627AU , Muses8920 etc,etc..))
by that they say in the description:”..Professional IIS verarbeitung chip realisiert PCM/DSD ausgang. 2. unterstützung 32BIT/44,1-384KHZ DSD64-DSD128 ausgang”, means they found apparently another way (“..professional I2S processing..” to output DSD over I2S (which i, we hadn´t got solved here (we used then a usb-bridge (or “new” now via HDMI))
u can also use an oled-display (+10$) directly connected (see pictures)..
else nothing new from here, greets for now !! 😉
