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->

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>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 ) ->

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 !! 😉


essabre-90xx-rpi.sfb2 has moved / Arduino + SSD1306 / ESP32 Bluetooth-serial / 3D-printer case

so, 😉
essabre-90xx-rpi.sfb2 has finally moved..was a bit more work then expected, right now i´m not 100% satisfied with the result->had btw. to change the symlinks-structure in wordpress, so some pics/categories will have another url + the „direct“-forum-link (at the top) has changed to a „2-click-experience“ 😉 + some minor changes, but overall i think its now a little bit faster + on a newer OS + a newer php-version..

second i´ve ordered some SSD1306 mini-tft-display test-wise some months ago, set it up on the third !! Arduino Uno finally (i´ve ordered 2 other Unos „in-a-row“ and they were both damaged) and got the following result (for u to see it in real life, to maybe get some ideas for your DIY-DAC)..

absolutely easy wiring + sketch;.ino is here->Link

third got by chance some really simple ESP32 Bluetooth-serial tutorial on „Random-Nerds„; ( 😉 ) maybe interesting for you->
fourth no new Volumio-version is out and a new drop is the SMSL-SU 8 Version 2 with two (dual) ES9038Q2M for 200$ instead of 250$->Link


fifth, no other news concerning the ES9038Q2M, nothing spectacular in the about it->
sixth i´m still planning to buy some 15V-0V-15V toroidal transformer and for the case i was looking for some „3D-printer“-layouts/submittals; had found a site (don´t know the url right now) and maybe we could make a new „thread“ here or at the forum, for some „3D-printer“-submittals for the case !!

more to come + greets for now !!

Massdrop: SMSL SU-8 Version 2 DAC 200$ Dual ES9038Q2M + Volumio 2.565 (12-03-2019)

so folks 😉 ,
sorry that i lately post so much „massdrop“-related things, but this is first an audio (ESSabre)-site and second heavy related to the ES9038Q2M 😉
as said, DUAL ES9038Q2M on it, some additional specs:
Input: USB, optical, coaxial
Balanced !! Output: RCA, XLR 
USB sampling rate: PCM: 44.1–768 kHz; DSD: 2.28224–22.5792 MHz
200$ (instead of 250$)
(PS.: and btw.: u get 10$ „start“-bonus !! if u join massdrop via these – link(s) (on the site + right via the „widget“(„Xavier“)) !!..
so hop, hop and join !! 😉 )
(„display-wise“ its not soo great, but for all these problems we have here on essabre-90xx-rpi „tons“ of display-tuts and possibilities (for DIY)) 😉

Driver (Shenzhen-Audio) are here (XMOS V4.47)->
and an review is here ->
interesting at this review is the following „SINAD„(some distortion-/noisemeter)-diagram, with some „oppononents“ like Benchmark DAC3, Schiit Modi USB, Chord Mojo, Katana, Auralic Vega and such->

by that some new „Volumio“ is out (now at VERSION: 2.565)->LINK, some fixes, and since V2.527:->Add direct DSD Support to many USB DACs, Mpd 0.20.18 version.. its a little bit on „hold“, just ordered (as said before) some Burson V5i-D and can then report about the Op-Amp and the „general“-massdrop-experience..

greets from here for now and stay tuned !! 😉

New XMOS-USB-Driver (Skysong/Singxer) -> v4.59.0_2019-02-13 + Massdrop ES9038Pro

hi there, 😉
found by chance on then shenzhenaudio-website this new XMOS-USB-driver V4.59 (02/13/2019) originally for the Singxer SU1/SU6;
tested here with with the Skysong(Singxer)-XMOS-USB-device (XU208)(+ES9038Q2M) on Win10 -> works fine !!

by that there is some Dual !! ES9038PRO on Massdrop->

->Dynamic range: 131 dB
USB: PCM 44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384, 705.6, 768 kHz

interesting is the separation from the device + power supply..
it is the same principle as maybe earlier with the Mission Cyrus Amps 1-3 with an extra PSX which cost the same !! (and i had luckily here) and which remind us on the great importance of a clean, strong power supply !!

New Dual ES9038Q2M out !! + new Volumio ES9038Q2M-plugin !! (HW-Vol. + DPLL etc.)

so, 😉
in visiting this great,great, (as said a million times before and link also in the „sidebar“)-> we have now here first a new „Dual ES9038Q2M-DAC/board„; it has also „a lot of shit“ as a bluetooth-receiver and such on board, but has also an HDMI-I2S-input, see post before..(the board itself is also from „SMP CB“ (like „our“ green-ones))

160-200$ roundabout->Aliexpress-Link..

by that, and thats most important, someone over at the „DID IT“ 😉 , means software-control on some internal register, HW-Vol, DPLL-settings and so on / unbelievable !!..

i dont want to write here too much about it (NDA and such), just head over to the forum-> and u will be absolutely fascinated !!

also i found just now by chance a github-repository for a driver/.dtbo for the AK-4137 on a ES9028Q2M (hifibunny-driver) or ES9038Q2M->also just discussed in the forum..->Github/TuziUsagi->

more to come, merry christmas and many greets for now !! 😉

HDMI I2S LVDS to I2S /-modules / incompatible XMOS-driver V4.45 Win-10 / new ESP32s

so, 😉
in waiting/looking for a toroidal 15V-0-15V transformer and the right case and thinking about the „maximum“ 😉 DIY-DAC + connections i came back again to some HDMI I2S LVDS to I2S-connections/modules..

Audiophonics has some there (25€+shipping)-> (u can get the same here for 21$ without shipping (costs)->
interesting by this „Audiophonics“-module is the selectable dual-I2S-input option ->

(u can get single „ones“ here for 15$->

meanwhile i think u have to include such a „I2S-HDMI“-option because we got more and more USB-bridges with I2S-HDMI-out like the Gustard U-16 (see some earlier posts, LINK ) or some Singxer SU-1 for example..

Audio-GD also made equipment with this connection and interesting would be if it has great benefits in modding a „transporter“ means CD/DVD-Audio/Bluray-player and so on to bypass the spdif-connection/conversion and directly connect the transporters internal I2S-connection to an I2S-HDMI output module like this:(Link)

by that it is recommend only to use (hdmi-)cable shorter than 50cm->“..which needs to be kept as short as possible to uphold decent signal integrity“..
Kitsune for example has some there also by only 30cm (as example)(9,90$)->LINK
by that, i´ve faced some incompatilibity issues with the XMOS-USB-driver V4.45 (on my Skysong (Singxer)-USB-bridge) since the last Win10-updates (stuttering); reverted back to V4.36 (but still not „optimal“)..(link to the driver in the forum->Forum)

also i´ve got some new (Geekcreit Devkit V1-36pin) ESP32 from banggood (to have a spare)->Link 

it looks a little bit different and i also think there´s a „fresher“ Wroom32-module on it (newer revision)..

more to come, greets for now 😉

Op-Amps: Burson V5/V6 – AD797BRZ / ES9038Pro with Burson V5 / Gustard H-10 with V6

so, 😉
after i´ve re-checked my Op-Amp-„collection“ 😉 (in testing them on an ES9038Q2M) and reading a lot of op-amp reviews again, i´ve ordered a few days ago some AD797BR(Z) (as described in some posts before)..

The „B„-line has a stricter factory-selection/-fabrication and is mainly considered as the best AD797 for audio..
by that, curiously, i got the most the site-/page-visits here op-amp-wise, means the main interest is also in the op-amp-section/part/reviews..
so i can/will hopefully test them in a few weeks and the next step (op-amp-wise) would be the „Burson V5/-6″-line..

was also clear, as said in the earliest posts..but they cost around 40-50$ (pair)..
(the third set of pictures here are some Burson V5 on an ES9038Pro->

some good toroidal transformer (+-15V) cost also about 30-40$ (min.) and so i/u have to check out which will bring the best „tone/sound“-enhancement (or both of course)..

(Link-Aliexpress or from Audiophonics or something)
„Webcontrol“-ESP32-wise its still in development but primary i think i want now to search for the right case, transformer..
many greets from here for now 😉
