Alsamixer-/control I-Sabre-K2M (-Q2M)=“Game-changer“ + Audiophonics ES9038Q2M Kali-Edition..

so, !! 😉
don´t understand/got it at first, but as „Terry“ sent us a link to the new Audiophonics-ES9038Q2M KALI-edition->, (Link-forum here)
i´ve looked through the description (after a few times visiting) and saw
„DietPi-compatible“ and this picture:

then i looked through some other audiophonics-documentation and there it says:(Link-Audiophonics-topic->LINK)
„..Audiophonics I-Sabre K2M DAC Board ALSA Driver !!“->“.. SatoruKawase/I-Sabre-K2M“ !!
and this is exactly the same repository „SatoruKawase/I-Sabre-K2M“which „Kennyliveforever“ mentioned and from, i guess, DietPi download the binaries for the changed „I-Sabre-K2M“.dts-overlay !
so, thats really a „game-changer“ !!
it´s so possible now to change the ESS-HW-control+FIR-selektion+Sources „on the fly“, means via an „alsamixer-terminal“ !!

millions of new possibilities“ 😉 (display and usability-wise)
(just tried here right now to change the filter-settings via an alsamixer-terminal->no success..same with input-selection+HW-volume-control..guess its audiophonics/mcu-specific; but nevertheless a great improvement !!)
I´ve just seen at audiophonics too that it is possible to upload some driver (in this case audiophonics-ES9028Q2M) via the plugin-upload option in Volumio !! (maybe we´ll get there some new/updated „generic“ ES9038Q2M-driver too !!)(LINK)

thats all wonderful, greets for now !! 😉

„Allo Katana“ on the way->.dts accepted for rpi-mainline-kernel; forum

so, 😉
the long promised „Allo Katana„, a „monster triple-dac“ hat->controller+psu/dac/output and with 6 Op-Amps from Allo is appearantly in the last stage..
(picture is from here-> and relatively „fresh“ and/but i don´t know if this is exactly the promised Katana-DAC/HAT, but looks so..(95%))

by that if u really want some fresh/new audio-(dac-hat) info 😉 go to the phenomenal board
absolutely superb there; there are sooo much super interesting threads->for example this or and so on and on..(some Link is also in the sidebar on the right->links)
this site is absolutely „low-mo“ 😉 in regarding/comparison to the super interesting infos there..

by that, as said, the „allo-katana“-.dts was accepted by the rpi-mainline-kernel maintainer->(link maybe later) and i first thought:“yeah, then we finally have our es9038q2m.kos for the chip“, but they said, this .dts adresses the special mcu by Allo which adresses then the ess9038q2m-chip..

anyway, here is (imho) a super interesting excerpt of the code for the .dts file: (sound/soc/codecs/sabre-ess.c and sound/soc/codecs/sabre-ess.h) from here:->
it shows the different register of the es9038q2m (or in this case the allo-mcu but the basics are the same i think) + the adressing->

some user over there is also a few steps before reading out the mcus on our chinese-9038q2m-boards (i tried something similar a few months ago in trying to read out the mcu on a ES9028Q2M via the onboard SWIM-interface and with a ST-Link V2 but with no success)..
so, as said, very interesting, but go and visit these phenomenal forums !! 😉

ES9038Q2M V1.07 ->

so, 😉
some new, fresh pics from an ES9038Q2M (V1.07)..the I2C-pins are now reachable via a socket->

(don´t know what else has been changed)

(pictures are from-> and „pbla„; hope i can use them here; if not e-mail)
(PS.: i personally have absolutely no problem with it if somebody is using the/“my“ pics(here)/is linking to some pics; absolutely not !!.)

Thoughts about an upgrade to ES9038PRO->too expensive at present+DIY-audio-forum

so, 😉
thought about an upgrade to an ES9038PRO by example..
we´ve had here a post to a „HIFIME UDA38PRO DAC“->, 219€ and now looked today through Ebay and found this one:

roundabout 190$..->LINK
looks very nice manufactored, nice layout, 4 Op-Amps..
very interesting is also that they recommend:
„..default include NE5532*2 + NE5534*2 Op-amp
you can upgrade the op amps :AD797 AND muses8920“ (have absolutely the same opinion here too (and also at the „“; link at the right..)+ our „fabulous“ „OP-Amps recommended by ES-Sabre“-list->Link..

so, but nevertheless i must say that as i heard my combo („Blue“ES9038Q2M+Muses8920) after a little timely distance it is already a superb fine tune/sound..(but as said, u have to use Muses8920 or AD797 or similar)..

by that, some user at the phenomenal>Link at the right link-list also said that he also has the impression that the „Blue“-ones sounded „flat“ (as i said/posted before)..

so because it is already a really fine sound/tune here, and this 200 bucks are to expensive  for me right now/at present i guess i will maybe order some „Green“ ES9038Q2M (V1.06 or V1.07)->but/and „we“ have to be very careful in selecting the right ones, because there are also absolutely great differences on the „Green“-layouts concerning the quality of the layer+components !!)..->selected „Green“-one (V1.06) for now: Ebay 36€->Link
(interesting feedbacks/ratings btw. !!)

i´ve ordered some LME49720 and will test it against the Muses (next step would be to buy some AD797 or 2 LME49710)..

so i think its the best for now to stuck and further „experiment“ with the ES9038Q2M !!

(and provide it with some really great „Talema“ or something/similar 😉 )

Very,very interesting post by Iancanada@diyaudio-forum/ESS-controller…

so, 😉
came by chance about this post in the diyaudio-forum->
its from, Github->
Dimdim“ from the famous Hifiduino-project is also there and they discuss a project in which the „..Sample rate, clock frequencies, X*Fs, date length, PCM/DSD/DoP format..“ could be determined by a „signal format analyzer“ (developed by Iancanada) running on the ARM-processor/Raspberry Pi to „run the ES9038Q2M in high-performance-mode“ 😉 ..

a lot of really interesting infos !! (i dont write here some more cause i don´t know if i have the „permission“ for it..)
also with the pictures..i took only here one or two; hope its okay for Ian..(if not please mail) 😉 (i personally think posting here a lot of pictures from his projects could help him to sell more from it/have more budget to develop !)
a MUST read !! 😉

(interesting is also that he uses some STM32 for his „ESS-controller; we/i´ve made some tutorials/first steps with it here too)

(another interesting topic there is by „Mikett„; he says „ the end I stuck with the 49720. It sounded slightly better than the 5532. The 5532 seemed to provide better drive but the higher frequencies on the 49720 was better I thought.“ and thats absolutely the same as i feel/think about the „drive“ on a NE5532 and second about the LME49720 which ESS recommends (see the table in an earlier post)

ES9038Q2M: DAC DSD Decoder Support IIS DSD 384KHz Coaxial Fiber DOP+TFT LCD !!

so, 😉
absolutely fresh:“Our“ ES9038Q2M now with the promised I2C/TFT-display..!! 😉

Aliexpress->$79.90 – $96.90 (with and without Apple-TV-remote!!)>
Link-Aliexpress !!  (+NEW: also on Ebay->LINK)
(theres also another link on ebay; but its a little bit confusing because the picture shows „ES9028Q2M“ printed on the PCB->Link Ebay (63,66$))
this one from Aliexpress says: „ES9038Q2M VR1.07

(the second and third pictures are from Ebay)
absolutely great for now !! we can maybe use then a greater TFT(over I2C) and it looks that we havent then to read out the Anamero(XMOS-)-boards for the sample-rate+format !!(+it displays the filter-settings of course).
so we have a lot to test out in future !! 😉
