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i´ve found a few days ago some „withdrawn from service“ 😉 Telekom (uarghh ;-( )  Media Receiver 303A-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 !! 😉

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

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/Grigoryun-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 !! 😉

Raspberry Pi 4B 2GB arrived / Volumio now at V2.714

so, 😉

finally the Raspberry Pi 4B 2GB arrived here->still an improvement in sound-quality and clarity..less jitter, more exact due to more processor-power and when u first power on your raspberry (here with an XMOS-bridge and then via I2S to an ES9038Q2M) u really got the the feel that the Pi is made for music !! 😉 (i think its also because of the short electronical circuits on the board, absolutely low latencies))..

absolutely fantastic, beats absolutely a lot of other DAC/PC/USB-combinations, wonderful 😉

fired it up with Volumio V2.714, its now with a changed UI->https://volumio.org/get-started/

plays here DSD256 without any problems (see other posts here for configuring Volumio with an XMOS-bridge)..->

and because the Pi 4B has finally a Gbit-Lan + USB3.0 (and more Ram + processor-power) its makes now so much fun to browse through your media-libraries and play it („instant“), great 😉

nothing else special, particular by now but many greets and stay tuned 😉

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 !! 😉

Xduoo Link arrived / okay, easy handling, not so hi-fi as ES9018K2M for example..

So, 😉

finally the Xduoo Link from Massdrop arrived (Link)..cost was 38$, absolutely easy handling, Windows 10 detected it without a problem (see pictures), was first a really little fun thing, also with a lot of bass/push at low frequencies(read that also elsewhere), but it misses the clarity in the high/-mids, not to mention the positioning or soundstage..

for 38$ its totally okay but if u are on hifi, some ES9018K2M chinese-board for 8,50$ (nowadays) is still a better choice ! (need some raspberry pi or USB-bridge of course; and not to mention the ES9028Q2M,ES9038Q2M->absolutely in another league !)

so, back to the Xduoo Link..interesting is that i had to change the channels (left/right)(plugs), its more source-depending (different recordings and so on), and its really on the edge to hifi in some areas, but in the long-term it could be annoying because of the not soo great SNR/Thd..

for 40 Bucks its still okay/maybe a bargain but don´t expect too much and as said, for hi-fi u still go better with the cheapest ES90XX here (ES9018K2M)..

but okay, its absolutely small and made for mobiles/IEMs; there are also some other there, ibasso etc..

its okay for me now, i primarily wanted to give my fabulous SkySong-XMOS-USB-Bridge a „rest“ (daily use with a PC) and for this purpose its okay for now..(didnt test the DSD256-compatibility yet, will maybe report then about it)

more to come.. 😉

Wharfedale Diamond 9.1 vs. Mission 760i/780 ->no comparison.. / ESP32-Cam

So, first: sorry for lately not soo much posting here .. 😉

Second, and because this is also mainly a „hi-fi“-related website i´m very glad to be able to post here also some speaker-experiences..

I´ve just bought some „Wharfedale Diamond 9.1 (white)“ to compare it with my old speakers (Mission 760i) and also to „upgrade“ my hifi-gear in general..

and because this discussion „which sounds better ->Wharfedale 9.1 oder Missions (lastet Centuries 😉 ) ?“-> i have now the answer:

Absolutely no comparison !!! The missions have a so much greater „soundstage/room/hifi-sound..“with them, really „hi-fi“ has just begun 😉 ..and because there´s always a „certain philosophie“ (sound-wise) behind the speaker-manufactories i would say the „Wharfedale“-philosophie is not mine/direction ;-). (guess i have to buy some Dali Zensor, KEFs or monitor-audios next.. )

by that i´ve bought some ESP32-Cam-Board + Cam(5,99$)->will post some experiences with it later !!

many greets from here 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 !! 😉
