Drop of the day/week: Zorloo Zuperdac-s ES9018Q2C / only 40$ (with essabre-bonus only 30$ !!)

Kommentar hinterlassen

so folks, 😉

sorry that there were lately not so many news here on essabre, but no worry, i still plan to buy some toroidal transformer; by that i got an old SONY MDS-JE 520 MD-player/defect and first thought to use it as a case for a combined raspberry pi (as lan-player) + ES9038Q2M + XMOS-bridge + ESP32/Arduino (display-wise); maybe in the „long-term“ 😉 ..

but first a really,really interesting drop !! :

Zorloo ZuperDAC-S (ES9018Q2C)(40$ !!)

Zorloo ZuperDAC-S with an ES9018Q2C for only 40$ (if you first join massdrop via these essabre-links (LINK) or right in some widget(„Xavier), u got 10$ „start-bonus“ and you will get this for only 30$ !!)

(other specs: 120 db SNR, Volume control: Integrated, 16 steps, works independently from host (last setting is stored)

by that, a few months ago i also planned to buy SMSL Idea (Sabaj DA2) , they are meanwhile also only at 59$ i guess; they are btw. with the same ES9018Q2C..

anyway, maybe its worth to give it a try/shot !! 😉 (and it would be super nice, if someone here or at the forum could write a review and post it !!)

so stay tuned for now, more things definitively to come,

many greets !! 😉

(and sorry for the color-choice of some text, wordpress changed to „block-mode“ 😉 , and i have to learn/work on it 😉 )

For the last time: real DSD/Dop via volumio->usb-xmos-device->I2S->ES9038Q2M

Kommentar hinterlassen

so, 😉

as we had it here in discussion:“is it possible to get real (native) DSD/Dop on the ES9038Q2M to work ?“ (with the DSD-lock-light on<-thats important because foobar for example indicated „Dop“ but it is internally converted to PCM and the DSD-lock-light stays „off“)

(SkySong->full blue DSD-indication (DSD256 in this case) + DSD lock-light ES9038Q2M)

in my experience here now/to date u can get it only with Volumio (or similar) and via an usb-connection to an usb-xmos-device and from there via I2S to the ES9038Q2M/Pro etc..(its also about the native-usb-audio-driver in linux)

I didnt got DSD to work via the „normal“ I2S-connection on a Raspberry for example..(and i/we tested a lot..)

I have now here a DSD256-file, playing it in volumio with the following settings: (for newbies 😉 )->no mixer, no resampling..

greets for now !! 😉

New XMOS-Xu208-device / Leaf Audio 2017/8/2 / Thesycon eval. driver 4.13

Kommentar hinterlassen

so, 😉

after i´ve decided to give my „good-old“ very good Skysong XMOS-XU208 a rest/use it only on my raspberry via volumio and usb to get finally real DSD/Dop (means DSD-lock-light is on (on the ES9038Q2M))(more later/in a later post), i´ve ordered a second device via ebay/cost around 30€, its a „Leaf Audio“ with also an external 5V-option + Coaxial-out (up to 192khz)

first impression: very light (in weight), but looks relatively „hi-fi“; first sound-tests: very „exactly/with contur“, but not so with the fine resolution as the Skysong->it depends also on the oscillators on the board (see pictures)->this is the „cheap“-version..the skysong has more high-end-ones..(but the skysong costs double of the price (around 60€)..

„Driver-wise“ it installed „Microsoft HiFi-DSD“ (never seen it before), thought it would install „xmos-usb“ or similar..

for that i couldnt got the driver from the seller, i searched for some and because i also got a „XMOS DFU“ in the device manager i´ve downloaded some driver-pack from thesycon with dfu support; its here (link) (see pictures)..

more later…

many greets for now !! 😉

Bargain of the day->Topping D50S ! (Dual ES9038Q2M +XU208 +BT + Remote) / AK4137 SRC

Kommentar hinterlassen

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$ !! ->
LINK
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->https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-new-topping-d50s-dac.7914/

also they made some minor sound-improvements (all in the article)..

https://drop.com/buy/topping-d50s-dac?utm_source=linkshare&referer=Y6KDJ4

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 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 !! 😉

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

Kommentar hinterlassen

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->https://randomnerdtutorials.com/esp32-bluetooth-classic-arduino-ide/
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 diyaudio.com-forum about it->https://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board-446.html
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 !!

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

Kommentar hinterlassen

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.. (more > Nuforce Udac5 in Part 2)..
greets for now !!
