found by chance this new ESS-Baby 😉 in searching for new driver on shenzhenaudio..
Gustard U-16 (ES8620) !!
->“Adopting the latest USB audio interface solution ES8620 from ESS, USA
Supports up to PCM 32bit/768KHz and DSD512, and supports both DoP and Native DSD.
ESS’s USB interface chip design is a completely optimized architecture for high-quality digital audio signal processing. It is not a general-purpose chip with USB digital audio interface code, so it has immediate impact on sound quality improvement;“
„…128MB SDRAM is used as the system buffer and digital audio processing FIFO..“
„..the machine uses up to three FPGAs to implement USB audio interface clock management and external 10M clock part of the audio clock frequency synthesizer..“
first (interesting) review i found is here->https://www.dastereo.ru/t/gustard-u16-debyutnyj-konverter-na-es8620-xmos-amanero-upali-otzhalis/28117
didnt find any real opinions/soundtests against the other ES-chips till now (Update: and i guess i won´t find any at all because it is (unfortunately) only a „usb-bridge“ (more or less)->“High performance usb digital audio interface“ 😉 )
more to come, greets !! 😉
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 !! 😉
by searching for the right settings to play real, native-DSD i came by chance about this tool->TEAC Hi-res-editor (WAV/DSD/DFF)
very interesting was, and thats why i post it here mainly, is because i couldnt play (flacs) above 192khz in VLC for example in Win8.1 (Win10) with the XMOS(Skysong)-USB-bridge and our lovely chinese-sabre-boards (ES90xx..)
i could select 24bit/384khz in sound-properties (XMOS-USB-Audio), could „generate“ a test-tone, but playing flacs in 384khz by example was not possible..
I´ve installed this „Teac-Hi-res-editor“ and surprisingly i had my 384khz (VLC) in Win8.1(Win10) !!
think it had installed some driver from which i was not aware of before..
second, the main very interesting feature of this Teac-Player/Editor that u can select the different DSD-rates (DSD64-2.8M,DSD128-5.6M and DSD256-11.2M) via the „play-frequency“-dropbox and it switches/plays through it->the Skysong(XMOS-USB)-bridge „clacks“-through and changes the LEDs accordingly to it !!
wonderful and absolutely easy !! (i had the ES9018K2M connected and have unfortunately a white noise at these rates (the PCM-rates up to 384khz are working well), but will test it with the ES9028Q2M and the ES9038Q2M)..
anyway, absolutely simple and very prolific !! 😉
(u must change the audio-driver in the audio-driver settings to „ASIO“ of course-> see pictures..but soo easy, great)(if u have no „ASIO->(XMOS USB)“-option try to install the xmos-driver V4.36 or V4.45 again (here singxer/skysong-driverpack))
greets for now !! 😉
after i tested „Archphile“ with the Skysong-Xmos-USB-interface and still don´t know to limit the DSD-rate to the DAC/-combo (it uses 705600 but the ES9038Q2M doesnt support it, i got only a heavy white noise), tried everything in the /etc/mpd.conf; i used again „Volumio“ as it said in one of their forums something about their DSD-native/DoP-compatibilty..
so let it run and hooray, the DSD-Led on the ES9038Q2M + the DSD-indication on the skysong-bridge were lit !!
(hadn´t got the DSD-indication before afaik).
wonderful, true DSD/DoP-sound !! 😉
had used foobar2000 with the Asio-driver/DSD-processor, the singxer audio-panel said:“Asio active(PCM-mode)-352800khz sample-rate“, see 2 posts before, but meanwhile i think it was converted !! to PCM- (with soxr by example) >because i hadnt got the DSD-led on and it wasnt not such a great improvement to „normal“ PCM..
now with volumio it sounds absolutely fantastic, absolutely real DSD-„sound“ !! („real“ DoP)
by that i´ve think meanwhile „Archphile“ is for the really high-end USB-DACS->384khz,768KHz (and above); think its about the „Arch-linux ARM“-kernel/core..
also u got a wonderful „Alsamixer-volume and master-clock“-mixer for the XMOS-USB-audio interface (with the command „alsamixer“)->
also interesting in Volumio is that if use the „resample-option“ in the settings it affects also the „DoP-chain“->set at 384khz resample/sox/very high, got my red light (PCM) on the bridge on and no DSD-light on the ES9038Q2M..
interesting II. is that u can resample up to 768khz (in Volumio) and u can hear something (but heavy white-noised) on the ES9038Q2M although somebody posted it can only play/(is capable of) up to 384khz in „asynchron-mode“; but i heard here something..->
greets for and more to come !! 😉
in trying to play finally some real/Native DSD on some (our „lovely“ 😉 ) chinese ES-Sabre-boards i came by chance about the „Archphile“-distro->https://archphile.org/ (knew about it , but hadnt got the time to test it till now)
it uses mainly the mpd-subsystem and i´ve read some days ago that it also could be a driver problem/xmos-usb-driver thing on linux to get DSD-native to work..!!
so and today after imaging the archphile-archive, and first i must say its really hard/difficult to „understand this archphile-distro“, because u got only a MPD-user interface with almost no settings (for the DAC for example and so on), u have absolutely to work over SSH in first place..
so but the really interesting thing is this->
first picture is the output of the „alsacap“-command (its Arch-linux)->
absolutely super fantastic !!! it says that the XMOS-USB-device (Skysong) can handle up to 768khz (via linux usb-driver)!!!
(a problem could (may) be that it didn´t show the „DSD_U32_BE“ sample-format which is normally a clear point/-„ means that this DAC supports Native DSD in Linux„.)
but anyway absolutely fabulous !!
and much more fantastic is that it sends 705600 !! to the xmos-usb !!!->(with the „perfcheck“-command)
by that, „Archphile“ has a very good/clean sound; sounds better than the picoreplayer for example (IMO), really,really clear !!
but got a really „destroyed/white noise“-tune with these 705600 on the ES9018K2M(and didn´t find a way here right now to lower it down to 352000 for example); have it really hard to work it out here at present; (the ES9018K2M has lower capabilities DSD-wise than the ES9028Q2M or the ES9038Q2M for example).
flacs (all up to 24/192) are playing very,very well..but anyway as said, really,really great news !!
more to come !! -> greets for now !! 😉
as said in this post->http://essabre-90xx-rpi.sfb2.com/2018/08/singxer-su-1-driver-update-v4-45-06-juli-2018-v7-24-i2s-hdmi-pinout-matrix-x-sabre-pro-9038pro/ i had now the time to test the V4.45 (we had V4.36 (Singxer_USBAudio_v4.36.0_2017-11-14_DSD512.rar)) on Win10 with a Skysong (Singxer) USB-XMOS-XU208 + ES9038Q2M and it sounds great (especially also on foobar in DoP)..->Link
i surmise its slighty slightly a little bit better (almost „hypothetical 😉 )(but in foobar in DoP (DSD128) its great as said)->
more about it (+file+link) in the forum->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=75
greets for now 😉
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.. 😉
