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 !! 😉


New XMOS-XU208-device / Leaf Audio 2017/8/2 / Thesycon eval. driver 4.13

so, 😉

after i´ve decided to give my „good-old“ very good Skysong XMOS-XU208 a rest/use it only on my raspberry via volumio and usb to get finally real DSD/Dop (means DSD-lock-light is on (on the ES9038Q2M))(more later/in a later post), i´ve ordered a second device via ebay/cost around 30€, its a „Leaf Audio“ with also an external 5V-option + Coaxial-out (up to 192khz)

first impression: very light (in weight), but looks relatively „hi-fi“; first sound-tests: very „exactly/with contur“, but not so with the fine resolution as the Skysong->it depends also on the oscillators on the board (see pictures)->this is the „cheap“-version..the skysong has more high-end-ones..(but the skysong costs double of the price (around 60€)..

„Driver-wise“ it installed „Microsoft HiFi-DSD“ (never seen it before), thought it would install „xmos-usb“ or similar..

for that i couldnt got the driver from the seller, i searched for some and because i also got a „XMOS DFU“ in the device manager i´ve downloaded some driver-pack from thesycon with dfu support; its here (link) (see pictures)..

more later…

many 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$ !! ->
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)..


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 !! 😉
