New: Topping D10s (1 x ES9038Q2M) vs. SMSL Sanskrit 10th SK10 MKII (AK4493)

Kommentar hinterlassen

hi there, 😉

unfortunately nothing new from here building/buying around some new ESSabre (9038Q2M) chips (DIY) but 2 new, interesting DACs „came up the table“ lately:

The Topping D10S with 1xES9038Q2M in it, XMOS XU208 + OPA2134  (changeable)->

goes for only 99$ !!  (Amazon,Aliexpress,Ebay,Audiophonics,Shenzhenaudio)..

a very detailed test about it is here (as always „audioscenereview“)->https://www.audiosciencereview.com/forum/index.php?threads/topping-d10s-usb-dac-and-bridge-review.14859/

and/or the SMSL Sanskrit 10th SK10 MKII for a little bit more (110$)  (Amazon) ->

audioscenereview-review is here->https://www.audiosciencereview.com/forum/index.php?threads/smsl-sanskrit-10th-mk-ii-dac-review.12148/

question is which sounds better ? (i will make a new thread about it in the forum (Link) and hopefully someone will/can post his/her experiences with both of them)

as i originally wanted to buy some Topping D50S (2xES9038Q2M, 250$ Amazon) because of the 3 inputs (USB,coaxial,toslink) the Sanskrit would be the better choice..

but as i like these phenomenal, unbelievable, „airy“, „openstage“-sound from the ESSabre-chips sooo much, its the question if these AKM4493 were sounding similar..

more to come… (gather some more information about them (the two) right now) 😉

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..

Kommentar hinterlassen

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)

ESP32-Cam / .ino / Port forwarding / „Solar“-category !!..

Kommentar hinterlassen

so, 😉

have now the time to get a little bit more „in-depth“ with the ESP32-Cam..You can get it meanwhile for 5-6$ from Aliexpress,Bangood etc..(LINK,LINK)

u need an FTDI-programmer for it of course, 1,50$, Ebay->(LINK)

a very good tutorial about setting up the ESP32-Cam, how to connect to the FTDI-programmer + sketch is here->https://randomnerdtutorials.com/esp32-cam-video-streaming-web-server-camera-home-assistant/

the sketch is also very „easy“ (see on randomnerdtutorials) and for „flashing“ u only need to set a jumper on IO0+GND (and remove it afterwards of course 😉 )..The .ino/sketch is also here->(LINK)

the picture-quality is a little bit better that u might expect in the worst case 😉 and now i use the ESP32-cam directly over (DHCP)-WLAN connected and display it in a browser (simple IP-adress in the bar) or via some dyndns-provider (use here spdyn.de in Germany)..

u only need to port forward (90 to 80 for example) it directly to the device..

very nice thing, use a raspberry pi zero wh as a webserver, mqtt-broker „in between“ and will also use then some ESP32 for solarpanel-control/measure the current from the batteries and display it on a website/handy etc..

more to come..also ordered some „step up module“ to easier power them with 5V/2 cables“, Ebay,->(LINK)

by that i made a new „category“ (on the right)->“SOLAR“ 😉 ..i will post there anything about 5V/12V solar-panels, autotracking them etc. !! all with some Arduinos,ESP32,Raspis etc..very much more to come,

(above picture + description is from : http://b04forum.dl3ndd.de/viewtopic.php?f=18&t=365)

but many greets from here !! 😉 (but no worry->essabre-90xx-rpi.sfb2.com will stay absolutely more hifi-related !! 😉 )

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..

Kommentar hinterlassen

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 !! 😉

Singxer/XMOS-audioclass2-driver now at V4.67 -/ firmware-repair on „bricked“ XMOS-devices

Kommentar hinterlassen

so , 😉

many, many thx to our great user „Grigory“  😉 we have now new Singxer/Skysong/XMOS-device-driver at V4.67 ; they are from here ->https://download.shenzhenaudio.com/Singxer/Singxer_USB_Audio_Class2-Driver_v4.67.0.rar

(they are also in the forum ->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=431 + here -> http://essabre-90xx-rpi.sfb2.com/driver/Singxer_USB_Audio_Class2-Driver_v4.67.0.rar

but most important and what is absolutely more thrilling is that „we/Grigory“ un-bricked a xmos-usb-device/Skysong-bridge !!! 😉

„Grigory“ posted the steps + (software-) tools in the comment-section of this post -> http://essabre-90xx-rpi.sfb2.com/?p=448#comment-2106

i think the key-point is these github-repository from which u can download/use the python-dfu uploader/downloader which u can also use with other XMOS-devices than Singxer/Skysong; u only have to change the usb-pid-number to the exact pid of your bridge (more in the comments by „Grigory“ (and me))..

->https://github.com/respeaker/mic_array_dfu.git  (+https://github.com/respeaker/usb_4_mic_array

(a little excerpt->rest see comments->

git clone https://github.com/respeaker/mic_array_dfu.git
cd mic_array_dfu/src

edit xmosdfu.c file and replace string
#define XMOS_XCORE_AUDIO_AUDIO2_PID 0x3066
to
#define XMOS_XCORE_AUDIO_AUDIO2_PID 0x3086 (for Skysong))

(the Skysong/Singxer firmware (V2.20) („extract“ from my bridge here)->http://essabre-90xx-rpi.sfb2.com/driver/firmware-skysong.rar

UPDATE: „Grigory“ made a fine tutorial on github about to flash some winbond-chip with a programmer + full „firmware“-packet ->

https://github.com/h0tc0d3/SkySongFirmware

so, i´m very happy with the whole „procedure“ because this was also a point essabre-90xx-rpi.sfb2.com was originally made for !! (to help other user/people with similar problems !!)

by that, „Grigory“ !! was so nice, and spent a little amount via paypal (u can also do it via the „donation“-button at the right bottom/widgets) to help this blog to stay alive.. 😉

but many greets, stay tuned and take care !! 😉
