Hooray !! Essabre-90xx-rpi teamed up with „Allo“..;-)

so, 😉
nothing spectacular new, essabre-90xx-rpi has now „teamed-up“ with Allo.com,

where u can buy such nice things like the „Allo Katana DAC“, LINK

or some „Vana-Player“ for example; LINK

or the phenomenal „Kali-Reclocker“ (64€ (incl.shipping)); LINK

and also some accessoires like this 5V power supply (3A) 13€ (inkl.shipping)..; LINK

will try to make some „deal“ with them that u as a essabre-90xx-rpi member or visitor get some kind of „voucher“-code or discount or similar..

Singxer SU-1 Driver update V4.45 (06.Juli 2018) V7.24 / I2S-HDMI-pinout / Matrix X-Sabre Pro 9038Pro

so, 😉
came by chance about this new „Singxer“ USB-Class-driver V4.45..we were at V4.36 and its directly from the same „shenzhenaudio“-folder/website->https://download.shenzhenaudio.com/Singxer/SU-1_driver_7.24_update/,
where we got our lovely „Singxer_USBAudio_v4.36.0_2017-11-14_DSD512.rar“ from; i will test it here; but my ES9038Q2M is now connected to the Pi; will see..(post the driver-pack at the forum too->Link)
The Singxer SU-1 is equipped with one ES9038Q2M + a XMOS XU-208->https://www.amazon.com/Singxer-digital-interface-XU208-DSD256/dp/B01N1OQY1A, https://kitsunehifi.com/product/singxersu1black/

by that i saw some I2S-HDMI-port pinout on the „Matrix X-Sabre Pro ES9038PRO 32Bit/768kHz DSD1024 Audio DAC„->https://www.shenzhenaudio.com/matrix-x-sabre-pro-es9038pro-32bit-768khz-dsd1024-audio-dac.html;
it says:“DSD1024 PCM768
As a new generation of Matrix flagship DAC, X-SABRE Pro not only supports 32Bit/768kHz PCM audio stream playback, but also supports DSD64, DSD128, DSD256, DSD512, and even supports DSD1024 with the sample rate of 45.158MHz via IS input port.“

 

(thats all „old“ stuff; but just to remember)

greets for now.. 😉

New Picoreplayer is out->V4.0.0 beta 5 + Moode 4.2 install instructions („moslog“)

hi there, 😉
a new picoreplayer is out->V4.0.0 beta 5->https://www.picoreplayer.org

its almost the same; like in this phenomenal 😉 , earlier post-> http://essabre-90xx-rpi.sfb2.com/2018/04/new-picoreplayer-is-out-v3-5-24-march-2018/

this time they have a rpi-kernel bump to Kernel 4.14.56, the DSD(Dop-)-„native patches“ are included, selectable..

tried to use the new „Allo Katana“-overlay here too on an ES9038Q2M->no success/didnt work/squeezelite refuses to start..

use now again (as described in the mentioned, earlier post) the „i-sabre-9023„-overlay, checked „384k“ and „bclk_ratio_int_div“ option, under „Card Control“..

got 32/384 without any problems, same with DSD-„material“->up to 32/352..(see also earlier post)..

but still a little bit „metallic“-sound; as described and still don´t know why..

Volumio“ for example has for my ears (IMO) a far far better sound/tune..

second:

a few days ago, i tried to install Moode 4.2 on a fresh raspian-stretch-lite..i knew there were such commands like „mosbrief,moslog and moslast“ for monitoring the installation progress; but i didn´t know how to use it correctly..

started the installation anyway, but as you see absolutely nothing !! u don´t know if it hangs/or is finished or something and so i had an incomplete installation after all..

so today i had the time to re-test it; in short: place a „ssh“-file in the root of the card (after imaging the raspbian stretch-lite on it); u can now ssh on it..make the commands for the mosbuilding (absolutely fabulous !! article about it in english here->Link and in german here->Link (fabulous !!)

after rebooting the first time (u first have to make a „hard-reset“, means unplug and re-plug the power (else it didnt work !!) u can now ssh on the pi again (while still working/compiling etc..) with now (and thats important too) ssh-login: pi and pass (thats new): moodeaudio

now u can type „moslog“ and can watch the installation progress, wonderfulst !! 😉

 


by that i´ve „demolished“ my lovely raspberry zero w ;-( , wrong soldered and so on (but this „soldering“ was, as said, more difficult than on an arduino or esp32-board for example)..

i still want to buy a new ES9038Q2M Green V1.07 and finally some OPA627, but have a small „cash-flow“-problem, „distinguished said“ at present 😉

will post then maybe more again 😉

Volumio v2.444 out / „Allo Katana“-support -> works on „chinese“-ES9038Q2M too !! / massive.. ;-)

so, 😉
a new Volumio is out->V2.444 ; its here->https://volumio.org/get-started/..
changelog says: „..Pi kernel bump to 4.14.56, Allo Katana support etc.“..
tested it here rightaway with the ES9038Q2M (2*AD797)->“massive“ 😉


but back to the Katana-overlay: at first „hear-out“ i´ve got the feel its more „massive“, more „accentuated“ (especially with the 2*AD797)..
don´t know at present if its the Katana-option, or the optimized Volumio-„footprint/improvements“ (see changelog)..
unfortunately i´ve got only 192khz/24bit with „audio resampling on“ (set it up for 384khz but got only 192/24)->

by that, there´s also a new „Volumio ESS9028QM„-option; works too (with the „Blue“ ES9038Q2M) (but didnt test if it reaches 384khz)..
but anyway there´s absolutely an improvement „sound-wise“ again !! „sounds“ again more „right“; really heavy, absolutely to recommend !! (RPI 3B-ES9038Q2M-2*AD797)

by that i´ve experimented a little bit more with „node-red“ and now with „MQTT-broker,-subscribe+publish“ and so on; really freaky, u can seamlessly connect an android app (->picture) with a pi zero as mqtt-broker and then via bluetooth (or websockets) to an arduino or esp32s..as said absolutely „whacky“ 😉


(„IoT MQTT Panel“->google/android-playstore->
https://play.google.com/store/apps/details?id=snr.lab.iotmqttpanel.prod&hl=de)

(this is as said, all for (in favor) of our lovely „DIY-DAC„-project , display and usability-wise)..
(will post maybe then more..)
but as said, really a sound improvement with the new Volumio (+“Katana“-option)..
greets for now 😉

Raspberry Zero W V1.1 + Volumio / I2S-connection + Dietpi-Update V6.12

so, 😉
its a little bit silent here lately but it doesn´t matter->here some infos about a Raspberry Zero W V1.1..
because they´ve updated the Arduino-ESP32-core here on github->https://github.com/espressif/arduino-esp32, and my self-made-noob-sketch didnt work since then on my Doit-ESP32S-V1 anymore, i thought also about to use my raspberry zero W V1.1 to control the ES9038Q2M via web or BT (for the I2C-control of the Digipoti MCP4131 for example, or the relais-control for the different-filter-settings and so on..)
for this (on a raspberry) „Node Red“ (a programming language/editor) looks like a very good attempt/approach..post maybe then a little bit more..
anyway first i have to get the zero to work with any of these chinese-ess90xx-boards..
I´ve ordered the zero w without a pre-soldered header and without a „hammer header“; u can get them so at pimoroni for example of about 13,50€ !! (incl.shipping)->https://shop.pimoroni.de/products/raspberry-pi-zero-w
(u can also get there a raspberry zero (without wlan) for 5,05€ !! (+3,50€ shipping)->https://shop.pimoroni.de/products/raspberry-pi-zero

but this self-soldering is IMO on this little raspberry a bit more complicated than normal, it was difficult to get an I2S-DAC-board on this to work..
heres again a little picture how to connect the I2S-lines: (the pin-layout on my zero w V1.1 is exactly the same as before (on a RPI3B for example) (because someone said there are different pin-layouts on different zero´s)

so, i have to use Volumio first to check out where the problem was (the soldering 😉 ), and i took the fresh 2.413 (https://volumio.org/get-started/)..
works absolutely fantastic here now with an ES9028Q2M (+Muses8920); almost no horrible pops+clicks at changing volume/tracks/audio-formats..
I use here now the „hifiberry-dac“ settings; the „RPI-DAC“ settings are working too (but be careful while using the hifiberry-dac settings->u have to set the target-bitrate to „24bit“(audio resampling on); else u get a horrible noise (but this was clear if u have followed this blog/read a little)..


as said, fantastic here now (i´ve originally wanted to use my old ES9023 for this; but got no sound at all (was this soldering problem 😉 )..
and by that u can use the raspberry zero W V1.1 also with a normal usb-cable on a normal usb2.0-port (500mA)..for me here its enough; hadnt to use the original Pi-power supply (2,5A or something)..
also, Dietpi is now at V6.12 and i still want to buy some green ES9038Q2M V1.07 and some OPA627 😉
greets for now 😉

„allo-katana-dac-audio.dtbo“ available now in DietPi V6.10

so, 😉
the „allo-katana-dac-audio.dtbo“ is now available in DietPi V6.10; means u can select „“allo-katana-dac-audio“ in DietPi->DietPi-config->Audio..
i´ve tested it here with a „Blue“ ES9038Q2M->no success/sound..
(i use the „i-sabre-k2m“.dtbo in DietPi->works very well with the ES9038Q2M here.)

was to be expected because (as earlier posted) the .dtbo adresses the mcu on the katana-board and apparently not on our cheap and lovely chinese 9038Q2M-boards..
else nothing particular new, except i really want to test some „OPA627“ (the „Bugatti Veyron“ under the OP-AMPs) and want to buy some new, green ES9038Q2M V1.07 ..
greets from here !! 😉

SRCs TI 4192 + AK4137 / Volumio-update / foo_out_asio foobar2000-component

so, 😉
as said, „we“ have to improve the input-quality (to an ES9038Q2M par example) jitter+dynamic-range/SNR-wise->“Dynamic range: 144 dB (-60dBFS input, BW = 20Hz to FS/2, A weight),THD + N: -140dB (0dBFS relative input, BW = 20Hz to FS/2) (excerpt datasheet Ti SRC4392) over I2S (directly to the ESS-chips) from spdif or USB..
Markw4“ at my praised diyaudio.com-forum (Link), has posted some beautiful pictures about it (hope i can use them here too, if not please e-mail)..
(he posted also that is very important to have a short, in best case shielded, SRC-I2C connection(-cable))..


so u use it before the I2S-input on the sabre-boards..
The Ti 4192 supports only sample-rates up to 212khz, the AKM AK4137EQ „Flagship“-SRC 😉 reaches per datasheet 768khz (PCM) + 12.288 MHz DSD and DR: 186dB !!THD+N: -150dB ->Link

(the first picture is with an AK4137-assembled board (80$)->Aliexpress-Link )

Markw4“ also said that it (the AK4137) sounds maybe „slightly better“..

some Ti SRC4392 is here (25$):-> LINK  

(u can get it also assembled+USB-port/connection (60$) -> LINK (as also posted earlier))

have to think about it 😉 ..

okay, next thing is that Volumio is now at 2.411 ->https://volumio.org/get-started/

and another funny/interesting fact is that as i´ve installed a new Win10, i didnt got foobar2000 configured with foo_out_asio although i thought i had all „components“ (foo-input-sacd, asio-proxyinstall etc..) correct „applied“, but i didnt have the „foo_out_asio“ selection (or asio at all)..

searched for the foo_out_asio_plugin but didnt find it (the right one)..

found it back in „our“ Topping DX4-driver pack->its here again foo-out-asio 2.1.2 (foobar2000 component)->http://essabre-90xx-rpi.sfb2.com/pics/foo_out_asio.fb2k-component
