Raspbi HAT ES9038Q2M / Ustars R38

Kommentar hinterlassen

so, 😉

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 !! 😉

Raspberry Pi 4 ->DSD(.dsf/.dff)-files over HDMI / HDMI to I2S-extractor arrived..

so folks 😉 ,

hooray, today the hdmi to i2s extractor (from audiophonics) arrived ! 😉 (more later)..

but first, these “Raspberry Pi 4 DSD over HDMI”-thing:

i´ve read the days that openelec, Volumio, Moode + picoreplayer are also capable to sent dsf/dff(DSD)-files via hdmi-out on the Pi-4..

thats also a very nice “alternative” because u didnt have to use an usb-bridge (which is absolutely + in every way necessary) to play DSD-files from a Pi-(X) to an “chinese” ES90XX-board..(we didnt get it to work only over I2S)..

the Pi-4 should now be capable of streaming (also multichannel-DSD) via HDMI (was not (or less) possible with the Pi´s before)..

i´m reading just now a lot of it and will post then more about it..

so, and yet to the (long awaited) “HDMI-I2S-extractor” 😉 ..

“rock-solid” (not soo heavy as the before mentioned Burr-Brown-implementation in the Philips Fidelio BDP9700), but very “steady”..

in first using and setting it up, it has 2 red LEDs flashing/blinking) and no picture/sound and i´ve read elsewhere before that u have to use a 5V external power-source (although its not necessary as per “description”)..

okay, feeded it with 5V,2A and had problems (again) with the I2S-line from the extractor to the “green” (SMPCB) ES9038Q2M, not soo with the JY “Blue” ES9038Q2M..

ended it up now with a coax-line from the extractor directly to the coax on the ES9038Q2M..(but only for now, for DSD(native) u need the I2S-line)

and got finally my lovely 192/24 😉

as said, very “solid”-sounding, almost like the Burr-Brown-Gear in the BDP-9700; very exact, another step in the “hi-fi”-direction..

so, the problem is now that my Sony BDP-S7200 should play .dsf/.dff-files (SACD in anyway) via usb/network, but don´t do 😉 

got/always say “file is corrupt or wrong media-format”, + i havent got a single !! SACD here, so i couldnt test the DSD-functionality (and that is/was originally the reason for all these devices lately !!) right now..(but i´m on it !!)..

and so, these Raspberry Pi-4 playing DSD-files via hdmi came to my mind..

(i do play here with volumio->usb-bridge->es9038q2m .dsf/.dff-files “in native” but for test here the hdmi-i2s-extractor)..

(will post a lot more about it)..

so, many greets for now, hope u enjoy the pictures, much more to come 

and stay tuned !! 😉

Little update: ordered the hdmi to i2s extractor from Audiophonics..

so folks 😉 ,

a little update concerning the hdmi to i2s extractor->

bought/ordered it right now from audiophonics->https://www.audiophonics.fr/en/diy-interfaces/digital-interface-board-hdmi-mhl-to-i2s-coaxial-optical-p-15388.html

->we´ll have to see how it works out here..

but according to another user @aliexpress (he bought it with a black plastic case) it seems to work (toi,toi,toi (german phrase) 😉 ) also with a sony blurayplayer (guess he played a SACD)->

(don´t know the excact Topping-model/series he had there)

so, much more to come, many greets from here !! 😉
