New XMOS-USB audio driver (V4.47) / SMSL 8A V3 / Winbond W25Q64 (Qxx) Arduino/ESP32S SPIflash

so, 😉
there´s apparently a new XMOS-USB audio driver, V4.47 (Link) (08-06-2018) out; found it first by reading some reviews for the Sabaj DA3 (->https://www.audiocircle.com/index.php?PHPSESSID=ktk1k2hchrlfmloktc0k3c5og0&topic=152638.340 ) and yesterday at an Audiophonics-Ad concerning the new SMSL 8A V3->https://www.audiophonics.fr/en/dac-without-volume/smsl-m8a-v3-usb-dac-es9038q2m-32bit-768khz-dsd-xmos-xu208-p-12934.html and also directly at Theyscon->current release : V4.47..
by that there´s also a new V4.41 from Thesycon/Jlsounds->Link forum..)
also the new SMSL 8A V3 has a „2nd generation XU208“ (259€)->

by that i´ve bought some new „Winbond W25Q64“ (64Mbit/8MByte) SPI-„serial flash-memory“ (only 1,29$ par example->Aliexpress) to use it maybe on an Arduino to display some graphics on the TFT-display and because the Arduino by example has a very low ram-amount (32kB !!) i wanted to extend the memory to store some data for the bitmaps..

On an ESP32S its not soo critical (4MB); u can store the bitmaps in the SPIFFS-subsystem but anyway i didnt find a „SPI-flash“-library for the ESP32S and the Arduino in general !! searched thousand hours on google and yesterday i found per chance this SPI-flash/library/tools on „RinkyDinkElectronics“->Link, the same guy who made this beautiful UTFT-library !! and which i used before ! 😉 ->Library : SPIflash

connected and it runs fabulously 😉

and hooray !! 😉 , i´ve finally ordered an „ES9038Q2M“-„Green“ V1.07, (i have a „Blue“-one here) to check finally out if there´s a „shitty“ PCB/components-problem on the „Blue“ or if they sound the same..

by that, next OP-Amp will be the „OPA627„(AU)->“The Bugatti Veyron on the Op-Amps“ 😉

many greets and more to come !! 😉

 

 

Volumio at V2.457 / Dietpi V.6.16 / mympd / upgraded ES9038Q2M decoder board I2S

so, 😉
after searching today for some new ES9038Q2M-boards/-infos, i´ve found also this „Upgraded version of ES9038Q2M decoder board I2S input OPA1612+AD8397ADRZ“ (it was also mentioned in these diyaudio.com-forum)->Link

it costs only about 42$ (incl.shipping), and interesting is (besides all the disadvantages like the 5V-9Vplug, the only-headphone 3,5mm jack and so on) that they use „OPA1612“ for the AVCC-section and some „AD8397ADRZ“ for the „output“-section..

i´ve googled immediately for „AD8397ADRZ“ and according to this post/article->https://www.head-fi.org/threads/audio-gd-discrete-op-amps-reviewed-opa-earth-opa-moon-opa-sun-v-2.397691/ its only in the „Category 2 – nice but incomplete sound“ 😉  (posted the link+excerpts also in the forum here->Link)

the author there also said, that for him (and thats interesting for me) the AD797BRZ (i have the AD797ANZ here) are the only ones in the „Category 5 – complete sound traveling in the clean air“ 
„..roughly, it’s like the AD79ANZ with all advantages of the OPA627BP added“ and as u know, i just wanted to buy lately an OPA627 (the „Bugatti Veyron“ on the OP-Amps) to „finalize“ my op-amp-experiences..
so i guess i have to check-out these AD797BRZ some time too 😉

another thing is that they are now at Volumio V2.457 (PI Kernel bump to 4.14.69 and some fixes), i´ve tested it immediately with the ES9038Q2M and the „Allo-Katana“-setting, and it was, as said in an earlier post, „massive“ (ES9038Q2M+2*AD797) again !!

 

this time had the chance to test it before with the ES9028Q2M-option (in Volumio) and some minutes before also with the i-sabre-k2m option in Dietpi V6.16..

last time i thought it could also be by the changed footprint/pi-kernel-bump but today i would say the „Allo Katana“-overlay is more specialized on the ES9038Q2M-core->

finally, at present, i must really say that i have the best sound (on all distros) with the newer Volumio (V2.452 and up) + „Allo Katana“-settings on an ES9038Q2M+2*AD797 !! (okay, its really tight between them but Volumio is absolutely easy to handle at present)

DietPi is now at V6.16, i just wanted to set up the new „mympd“-(fork of ympd), ran into trouble, theres a workaround now and its fixed in DietPi V6.17..(„Allo Katana“ works NOT on DietPi (with the ES9038Q2M) but with the „i-sabre-k2m“ overlay i got 32/384..)

more to come, greets for now 😉

 

Raspi-AK4137 single-HAT for 2/3B/3B+ Pi (30$) ; „Sonore“ ISO2DSD v7

so, 😉
thx to this phenomenal (post) in the diyaudio.com-forum->https://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board-278.html,
we have now here our AK4137 as a single HAT for the Pi !! 😉
as said in earlier posts, we have to improve the signal-quality(lower jitter and so on) over I2S->http://essabre-90xx-rpi.sfb2.com/2018/06/srcs-ti-4192-ak4137-volumio-update-foo_dsd_asio/


it costs only 30 !! $ and u can get it here->LINK
..The main function of this board is to improve the quality of the Raspberry Pi I2S signal and reduce jitter. And make up for the Raspberry Pi I2S output without MCLK! The original I2S output of the Raspberry Pi does not have MCLK and most high-performance DACs require MCLK to work. And the AK4137 reconstruction clock reduces the Raspberry Pi output signal jitter enhancement.
This board supports Raspberry Pi 2B 3B 3B+“..
so, as also posted earlier the AK4137 has 768khz (PCM) + 12.288 MHz DSD and DR: 186dB !!THD+N: -150dB ->AsahiKasei(AKM) datasheet->Link

(u use it between the Pi and our ES9038Q2M for example..a really long explanation on the other functions of this HAT is in the ebay-description above)

by that i came by chance (and according to the previous post) about this „Sonore ISO2DSD„-converter (a GUI for the sacd-ripper) + „Sonore DSD2FLAC„->


u can download both from here:
https://www.sonore.us/iso2dsd.html
https://www.sonore.us/dsd2flac.html

many greets for now !! 😉

Some new ES9038Q2M-things../ Raspberry Pi 3B+ first impressions..

so, 😉
some user at my praised Diyaudio.com-forum->Link said something about a new MShow-Audio „SU5-ES9038Q2M-DAC-HIFI-XU208-DSD-TPA6120-Headphone-audio-Amp-Bluetooth-5-0″->Link 160$, and interesting is that they used some AK4113 for SPDIF-conversion; posted here earlier something about it->Link; for me another „indicator“ that the „original“-spdif conversion by the ES9038Q2M on this board is not soo good as expected, as stated also earlier; better choice would be using some SRC4192 or AK4137->Link

by that, as thinking to buy some Green ES9038Q2M V1.07, including the display, i found some pictures with this display delivered/attached in „action“ and that looks not soo nice (frankly said) 😉 , so i think its better to continue to try to build an „own“ version (display-wise) 😉

by that i´ve bought some new Raspberry pi 3B+ (cause i´ve „fucked“ up my Raspberry Zero W with some ugly soldering) and first thing i can say about the new „wifi“ (N/AC) that i had yesterday (measured with iperf3) 84Mb/s (10MB/s) via N (Asus-RT56U); not soo good (expected 300mb/s)..
greets for now 😉

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..
greets for now 😉

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.. 😉

„Allo Katana“ on the way->.dts accepted for rpi-mainline-kernel; Diyaudio.com forum

so, 😉
the long promised „Allo Katana„, a „monster triple-dac“ hat->controller+psu/dac/output and with 6 Op-Amps from Allo is appearantly in the last stage..
(picture is from here-> http://www.forum-hifi.fr/thread-7848.html and relatively „fresh“ and/but i don´t know if this is exactly the promised Katana-DAC/HAT, but looks so..(95%))

by that if u really want some fresh/new audio-(dac-hat) info 😉 go to the phenomenal board diyaudio.com/forums..
absolutely superb there; there are sooo much super interesting threads->for example this http://www.diyaudio.com/forums/vendor-s-bazaar/310338-dac-allo-ess9028q2m-rpi-35.html or http://www.diyaudio.com/forums/digital-line-level/317577-allo-boss-dac-1-2-performance-4.html and so on and on..(some Link is also in the sidebar on the right->links)
this site is absolutely „low-mo“ 😉 in regarding/comparison to the super interesting infos there..

by that, as said, the „allo-katana“-.dts was accepted by the rpi-mainline-kernel maintainer->(link maybe later) and i first thought:“yeah, then we finally have our es9038q2m.kos for the chip“, but they said, this .dts adresses the special mcu by Allo which adresses then the ess9038q2m-chip..

anyway, here is (imho) a super interesting excerpt of the code for the .dts file: (sound/soc/codecs/sabre-ess.c and sound/soc/codecs/sabre-ess.h) from here:->https://github.com/raspberrypi/linux/pull/2519/commits/e67122b366f539713cf6ef91c63ab00cb269113d
it shows the different register of the es9038q2m (or in this case the allo-mcu but the basics are the same i think) + the adressing->

some user over there is also a few steps before reading out the mcus on our chinese-9038q2m-boards (i tried something similar a few months ago in trying to read out the mcu on a ES9028Q2M via the onboard SWIM-interface and with a ST-Link V2 but with no success)..
so, as said, very interesting, but go and visit these phenomenal diyaudio.com forums !! 😉
