Bargain of the day->Topping D10 (XU208+ES9018K2M+swappable Op-Amp) = 70$ !! / 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 D10, XU208+ES9018K2M+swappable Op-Amp option for only 70$ !! ->
LINK

it has „only“ the ES9018K2M onboard but also a „This DAC has a replaceable opamp socket, which allows you to swap in different opamps to change the sound signature.“..

Line Out

  • THD+N, A-weighted: < 0.0008% at 1 kHz
  • SNR, A-weighted: 115 dB at 1 kHz

USB In

  • 44.1–384 kHz / 16–32 bit
  • DSD64–DSD256 (DoP, native)

https://drop.com/buy/topping-d10?utm_source=linkshare&referer=Y6KDJ4

The DAC to beat (and effort) at the moment is the Topping D50 (dual ES9038Q2M)->Link but for test with a „manufactored“ XU208 + ES9018K2M – combo its maybe worth a try..
and with the specialized thesycon-usb-driver it can play DSD 128/256 without any problem..
as said for only 70$ (60$ if u first join massdrop via these essabre-links here(„Xavier“)) its maybe a first good test..
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 !! 😉

SFB2

essabre-90xx-rpi.sfb2.com will move (to a new server) + Nuforce Udac5 + SMSL SMSL X-USB II

so, 😉
unfortunately nothing new here in „modding“ the ES9038Q2M; still on the search for the right transformer->there are some on Ebay+Aliexpress+Audiophonics but didnt make a choice till now:(15V-0V-15V)

Moode is now at V5.0-> (http://moodeaudio.org/)

and as also said in their description->
„Most USB audio devices work with moOde via the Linux kernel USB audio driver but some devices with high speed UAC2 chipsets may require the USB (UAC2) work around in System Config“
„the way-to-go“ (and to get „real“ DoP/DSD) is nowadays (IMO) via some XMOS-USB-device->I2S->ES90XX..
we had it here in discussion, and with the new USB2.0(3.0) linux-kernel-driver u can achieve real DoP/DSD with the ES9038Q2M; and only then..
by that, as also said, with USB3.0, + a wonderful xmos-bridge (see some posts before) + ES9038Q2M u already have a superb „tune“, really near to the „unbeaten“ raspberry pi-I2S-ES9038Q2M-connection..(and its absolutely more comfortable)..
by that in speaking of a wonderful XMOS-usb-bridge we have now here a „SMSL X-USB II Digital Interface USB XMOS U208 to I2S LVDS HDMI “ (70€) with I2S->over HDMI which also said in some posts before, is the most „handiest „-possibilty to connect to an ES9038Q2M (with some I2S->LVDS converter directly connected to the dac-board)->

by that „essabre-90xx-rpi.sfb2.com“ will move next month or so to a new server due to cost/performance reasons; i hope i can move this site/blog/forum without great problems to the new location; excuse me then for any conveniance->a mirror (from this site) is just set-up at -> http://essabre.ddnss.org <- is just right now only for testing; the main url (essabre-90xx-rpi.sfb2.com will (hopefully, 99%) remain); u can test the above-url performance-wise..

Little update: Skysong XMOS-USB-Bridge external power supply 5V / interesting discussion „real“ DoP

so my dear visitors, 😉
after this little site got so much resonance (which i never expected) and i finally found the „real“ reason for the stuttering in my Skysong-XMOS-USB-Bridge – ES9038Q2M combo->it was the power-supply (more shortly) and i have got now such a wonderful/brilliant sound here + a very interesting discussion/topic was coming up concerning „real“ DoP (DSD) on the Sabre-boards with the „DSD-lock-light „ON„, i thought i maybe make a new post..
and excuse me, its all very „repeating“ here on the blog (said it before), but its a blog, with a little „Life-line“ and so we have to live with it 😉 ..
back to the first topic: as said in this post->http://essabre-90xx-rpi.sfb2.com/2018/04/es9038q2mskysong-singxer-xmos-usb-bridge-final-thoughts-settings-tone-optimization/->“..by that to provide the Skysong/Singxer USB-bridge with an external 5V power supply also boosted the overall performance of the Bridge by 10-15% !! absolutely to recommend !!..“ i had lately this „stuttering“ on the combo again, thought first the ESS-PCB/-chip is damaged, had not enough power etc.. but at present it looks like the wonderful,wonderful usb-bridge is getting a little bit older, and a few days ago in searching for the reason i plugged again the external 5V power supply in and hooray: the stuttering was gone and the tune/sound really improved again, so great, the positioning, the absolutely more exactly tone and so on !!
really,really wonderful bridge !!

(i´ve got the luck that i´ve got the „deluxe“-version with the golden Crystek + some other modifications; absolutely superb !! i´ve read somewhere else that the skysong-bridges are the ones with the „finest“ xmos-implementation and so on..i can absolutely confirm it from here !!)

the interesting thing is now that i was/am an absolutely Raspberry Pi-I2S-ESS Sabre-board fan/defender, absolutely superb sound, absolutely jitterless and so on (in comparison to any PC-soundcards or other DACs etc.) i must say, that such a combo with this skysong-bridge + nowadays USB3.0 (which had also a great effect on the „tune“ here (vs. the old USB2.0)) is really close/tight to it !!
it is an absolutely improvement via USB3.0 + some external power supply (as said), really close to some Raspberry Pi->I2S connection..

by that „Johnson Wu“ had a very interesting question (here in the comment-section on the right) concerning real „DoP“(DSD) sound with DSD-lock-light ON on the Essabre-boards->look at the comments on the right (or at the bottom of this post->http://essabre-90xx-rpi.sfb2.com/2018/09/volumio-now-at-v2-452-did-it-dsd-lock-light-on-es9038q2m-alsamixer-archphile-xmos-usb-audio-etc/#comment-1148

New ESS chip out !! -> ES8620 audio-solution (usb-bridge) !! / Gustard U-16

so, 😉
found by chance this new ESS-Baby 😉 in searching for new driver on shenzhenaudio..
Gustard U-16 (ES8620) !!

https://www.shenzhenaudio.com/gustard-u16-es8620-support-pcm32bit-768k-dsd512-dop-and-native-dsd-digital-interface.html(284$)
->“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 !! 😉

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 !! 😉

 

 

Little (Win)-exkursus -> foobar2000-alternative – Teac Hi-res Editor / ASIO-DSD / Win 384k

so, 😉
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)
->https://teac.jp/int/product/teac_hi-res_editor/top

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 !! 😉

Volumio (now at V2.452) did it->DSD/Lock light on ES9038Q2M / Alsamixer Archphile XMOS USB Audio etc..

so, 😉
after i tested „Archphile“ with the Skysong-Xmos-USB-interface and still don´t know how 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 !! 😉
