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->http://audiodiyers.hu/viewtopic.php?f=48&t=3615&start=50 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 !!.)
here is some beautiful pic by „Terry“ again on his DIY-audio project (an ES9038Q2M+Kali reclocker i guess); wonderfulst !!
also the attached TFTLCD-solution->the layout of the screen and so on..
a treasure chest on ideas for other user in building their own DACs !! fabulous !! so many thx again !! (we´ll maybe get more pictures in future !)
the LME49720 just arrived; i tested it here on an ES9028Q2M (DietPi-ympd, I-Sabre-k2M overlay):
for me too „thin„; it had a lot of air and liveliness/agility but absolutely, as said: „thin“..
after i put my Muses8920 back in i´ve got the feel: thats really hi-fi (with the Muses.)
but meanwhile thats all „whining“ on a high level and it really depends on your personal taste (on this high level->one wants to have more „push“, prefered more „rock“, the other one prefered more „classical“ music/tune and so on..)..
but nevertheless i would prefer the Muses8920 in comparison to the LME49720 by 15-20% 😉
(had not the possibility here right now to check it against the OPA2134/NE5532)..
the Geekcreit ESP32S arrived here yesterday (Link) (5,50€); 2 cores, wlan b/g/n, bluetooth on board, 4 !! spi-s and so on..think about how to use it for the DAC-control (spi-display,source-selection,filter-settings, HW-volume etc.)..
greets for now 😉
thought about an upgrade to an ES9038PRO by example..
we´ve had here a post to a „HIFIME UDA38PRO DAC“->http://essabre-90xx-rpi.sfb2.com/2018/02/es9038pro-new-es9038pro-out-hifime-uda38pro-dac-es9038pro-sa9227-219e/, 219€ and now looked today through Ebay and found this one:
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 „DIY-audio.com-forum“; 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 DIY-audio.com-forum->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 😉 )
hi there, 😉
a new picoreplayer is out->V3.5->https://sites.google.com/site/picoreplayer/home/news
new rpi-kernel/firmware, „..Updated to Squeezelite 1.8.7-1052, includes native DSD support.“, got it to work (ES9028Q2M) with the „I-Sabre-9023“ „card-control“, checked „384k“, Logitech Media Server is now at: V7.91->http://downloads.slimdevices.com/nightly/?ver=7.9
(nevertheless u have to activate the DSD-plugin under „plugins“))
sounds very „strong“, good, low latencies (thx to the new rpi-kernel+firmware and so on), got DoP with 352k and without any commandline-options like „-e dsd“ or „native DSD-patch“ and 384k PCM with „X“ (command-line-option)..
very „fast“ (low latencies) as said->absolutely the advantage of a very slim/less resources using system; no disruptive layer/driver..
(but as said, still with a little bit „metallic“-sound; don´t know why..)
came by chance about this post in the diyaudio-forum->http://www.diyaudio.com/forums/pc-based/302687-es9018k2m-es9028q2m-9038q2m-dsd-i2s-dac-hats-raspberry-pi-post5386371.html
its from email@example.com, Github->https://github.com/iancanada/DocumentDownload..
„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 „..in 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)
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 !! 😉
..some beautiful wiring pictures from some ES9028Q2M+/-38Q2M from a post/thread by „Terry“ at the forum (hope i can use the pictures here)->
+ some interesting measurements…
