Usability / Volumio->BubbleUPnp / Volume-Potentiometer-Hardware-None

so, 😉

sorry for the lately uninteresting/not so „fresh“ news about the ES9038Q2M/ES90xx-chips/boards etc..; maybe that will come back..

today, to keep this blog going, some usability-tricks/tips using a RPI-4B and volumio..->https://volumio.org/get-started/

runs fantastic (imo), is absolutely DSD-capable (remember to use an USB-bridge (XMOS or Anamero) „in-between“ and set volumio on „DSD-direct“,“no mixer“, „no resampling“-> else u wouldn´t get the red/torquise DSD-lock-light on the ES9038Q2Ms..->

by that i´ve tried a lot of dlna-apps for volumio and best for me so far is->BubbleUPnP->LINK

there are millions of other („Mediahouse etc.,etc.,“) but imo, BubbleUPnp correspondends superb with volumio..u can see in BubbleUPnP whats playing, can change the volume via the „normal“ volume-keys and u can also play/send .mp4/.mkvs etc.  to volumio and it plays only the audio/tracks..great ! 😉

by that i´ve bought a 10kohm-poti again (wire-diagramm here->http://essabre-90xx-rpi.sfb2.com/?p=1660  ) and although we have a web-volumecontrol with a MCP4131 „here“->http://essabre-90xx-rpi.sfb2.com/?p=1306

i still thought its „usability-wise“ better to use an old-school (analogue) poti but its still the same problem as first: u have only a very short range (i guess 35 degrees) from full to nothing and u have to turn it manually ;-)(but u are nearer on it 😉 )..still doesnt know the right conclusion for me, still in testing 😉 )..

greets for now and more to come !! 😉

again some new pics->DIY-DAC (ES9038Q2M) / 100.000 visitors..

so, 😉

because we have almost a 100.000 !! visitors here on the site (hooray, tomorrow i guess 😉 ), i post some additionally pics on the improvements of the DIY-DAC..

I´ve added some 0.96OLED (I2C) to display the data-format and rate (DSD/PCM-44.1k-384k DSD256 and so on); by that i use also 2 new LEDs (blue for DSD and red for PCM) to make the dac more shiny 😉 ..

problem was to get the information through the usb-bridge if it got DSD or PCM..will post then more about it..

unfortunately nothing „more“ new about these „whole“ ess sabre-things, maybe then more, greets for now !! 😉

(fifth picture is from a „Copland CSA100“->Quad Mono Sabre)

DIY-DAC: Telekom Media Receiver 303A as case/with 12V/3A power supply->as audio-streamer with Rpi4 + XMOS-USB-bridge + ESP32 as display-controller..

so, 😉

i´ve found a few days ago some „withdrawn from service“ 😉 Telekom (uarghh ;-( )  Media Receiver 303A->was first interested in the internal HDD->500GB Seagate, but have seen then this has also a built-in 12V/3A power-supply and its from the dimensions almost ideally as some Raspberry Pi4-ES9038Q2M-audiostreamer !! (not soo big) 😉

Display-wise its a little bit limited (due to the available space (height)) in the front, but some LCD1602 will maybe do it fine..

found then an easy way to connect some to an ESP32 via I2C and via some „web-remotes“ (see other posts here „Project-1“ etc..) we can select via some photocoupler/relais the inputs of the ES9038Q2M (Coax,Toslink, I2S/USB), adjust the hardware-volume, filter-selection and so on and can display the settings on the display/LCD1602) !!

so far so fine, but this is a heck of a lot work to do !! 😉 ..

(i´ve planned to use Volumio on the raspberry ->easy controlling via the web-interface, DLNA-capable, MPD etc..)..

as said, here at first testing-out some aspects/parts for it and a first result by example is that these 3A makes the „blue“ ES9038Q2M absolutely a little bit „airy(ier); had before some 2A power supply (12V)..

by that the „Leaf-XMOS-USB-bridge“ (->http://essabre-90xx-rpi.sfb2.com/?p=2066) is better than first thought..

+ also my new „ESP32“ will come to a new life 😉  (not to mention the Raspberry Pi4 2GB)

makes really a lot of fun here, and i will inform you about some further improvements !!

greets for now !! 😉

New Skysong-/SMPCB ES9038Q2M-boards + addons..

so 😉 ,

found by chance these new ES9038Q2M-boards..normally i don´t like the other/new boards different from the „green“ SMPCB, V1.06-V1.07 but there are some interesting details with it..

First, on the new, blue SMPCB they use some „DS9281“ for „better coaxial conversion, less jitter, less „lock“-problems, „better coaxial line“, like we know before that the original coaxial-line is not the best->link here->http://essabre-90xx-rpi.sfb2.com/?p=2058 and here->http://essabre-90xx-rpi.sfb2.com/?p=1833 , tags AK4118-receiverchip + SRC4192

Link Aliexpress/Ebay(35$)->https://de.aliexpress.com/i/32860202632.html?spm=a2g0x.12057483.0.0.580c31f9766Lc9

second, as said, i don´t like any other ES9038Q2M than the old green SMPCB, „Skysong“ from which had these phenomenal XMOS-USB-Bridge (see other posts before) also made a new ES9038Q2M with a lot of LEDs for the frequency-rate etc..(maybe these i would buy and only because they made such a great xmos-bridge)

Link Ebay/Aliexpress(44$ and up)->LINK

third, there are also some CSR8675-bluetooth->I2S-solutions->(with aptX, LDAC etc..)

Link Ebay/Aliexpress (29$ and up)->https://de.aliexpress.com/item/32860202632.html?spm=a2g0x.12057483.0.0.47897ef2tKiCRj

fourth, i still want to buy next a „Topping D50S“ (have to wait a little bit) and next month a Raspberry Pi4 with 2GB and still search some toroidal transformer 15V-0-15V for the green ES9038Q2M here..

more to come and greets for now !! 😉

For the last time: real DSD/Dop via volumio->usb-xmos-device->I2S->ES9038Q2M

so, 😉

as we had it here in discussion:“is it possible to get real (native) DSD/Dop on the ES9038Q2M to work ?“ (with the DSD-lock-light on<-thats important because foobar for example indicated „Dop“ but it is internally converted to PCM and the DSD-lock-light stays „off“)

(SkySong->full blue DSD-indication (DSD256 in this case) + DSD lock-light ES9038Q2M)

in my experience here now/to date u can get it only with Volumio (or similar) and via an usb-connection to an usb-xmos-device and from there via I2S to the ES9038Q2M/Pro etc..(its also about the native-usb-audio-driver in linux)

I didnt got DSD to work via the „normal“ I2S-connection on a Raspberry for example..(and i/we tested a lot..)

I have now here a DSD256-file, playing it in volumio with the following settings: (for newbies 😉 )->no mixer, no resampling..

greets for now !! 😉

Bargain of the day->Topping D50S ! (Dual ES9038Q2M +XU208 +BT + Remote) / AK4137 SRC

so folks 😉 ,
sorry thats its a little bit silent here on essabre-90xx-rpi lately, but there were a lot of other things to do 😉 , but i´ve just seen by chance this bargain on massdrop->
Topping D50S, XU208+Dual ES9038Q2M + BT + Remote for only 200$ !! ->
LINK
vs. „old“ D50->
the D50S (in opposite to the D50) a built in BT-modul (was at first sight, in aspect to the „ultimate hi-fi“, is not soo good) but also comes with a remote-control + had made some improvement „soundwise“, means they solved the „IMD ESS hum“, where at mid-levels, intermodulation distortion suddenly rises“..

very good test/article about the D50S is here->https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-new-topping-d50s-dac.7914/

also they made some minor sound-improvements (all in the article)..

https://drop.com/buy/topping-d50s-dac?utm_source=linkshare&referer=Y6KDJ4

as said for only 200$ (190$ if u first join massdrop via these essabre-links here(„Xavier“)) its maybe worth a try..
so and as lately said that the onboard spdif-conversion (on the ES9038Q2M) is not so optimal we have to look for an alternative and also somebody said at my praised diyaudio.com-forum->Link that „..upsampling to DSD is always better concerning thd/snr and so on, because of eliminating/move the noise in an unaudible range..“ and to reduce jitter i´m thinking about to buy some SRC4192..(SNR= 768khz, DR: 186dB !! ● THD+N: -150dB ) -> http://essabre-90xx-rpi.sfb2.com/?p=1833

there are some around for only 27$ on ebay->Link and the „high-end“-version with toslink and coaxial option + 1.3″ display (+ AK4118 spdif-receiver chip) for 80$->Link..

my goal at present is to raise the sq directly from a transporter via spdif and then maybe upsampled, but still more jitter-less to feed it in the ES9038Q2M..

will maybe then report more about it..

by that the raspberry 4B+ is out and so on..maybe then more,

greets for now !! 😉
