“The Hifime UDA38Pro utilises the ESS Sabre ES9038Pro DAC chip that has received a lot of attention and praised as the most important new DAC chip in ages…We have paired the ES9038Pro with OPA1622 output stage amplifier that can drive a wide range of loads including low and high impedance headphones and also line level loads like preamps and amplifiers… it can achieve up to 140dB !! dynamic range, -122 dB (0.00008%) total harmonic distortion plus noise (THD+N) in mono mode

Specs: (to come..)

ES9038Q2M: “Project 2”->building a BT-controlled HW-Volume-control (digital pot 10kOhm) MCP4131

so, 😉
because its a little bit silent around here lately, we still don´t know if the “Blue” ES9038Q2M has a “shitty” pcb and the “green”-ones sounds better, i have still buffer/”lock”-problems in windows using the V4.36 Singxer-driver on the Skysong-XMOS-USB in sample rates above 16/44 i wanted to use the onboard-HW-volume control, to which u can connect a normal 10kOhm-potentiometer (see pictures) easy..

 


i tested it here, and it works far not so good as expected and i guess u have a very small range of about 20% or so (in my feel) too..
i thought i could easy use the Arduino with analogwrite () and connect one pin to the middle of the onboard-3 pin but what i´ve read so far is that the Arduino can only send out PWM-signals so u need an external digital potentiometer (thats what i´ve read so far, don´t know if its true) and control it via the (in this case) SPI-bus/protocol..
for this u can buy a cheap MCP, in this case a MCP4131 of around 0,89€ and a Dip-8 socket (0,51€) etc.,etc..(more to come..)


(very good tutorial for this right now:

i will post here any “improvements” (and (maybe) a full tut) asap..!! 😉

Massdrop: SMSL IQ Portable DAC/Amp ES9018Q2C + Sabaj DA3 (2*9018Q2C)

so, 😉
no worry about the ES9038Q2M 😉 there are new ES Sabre-audio-chips on the way/in the pipe.. 😉
and because this is an audiophile-site i present here some (mobile-)DACs from time to time..->http://essabre-90xx-rpi.sfb2.com/category/dacs/
came by chance about this thing on Massdrop->https://www.massdrop.com/buy/smsl-iq-portable-dac-amp..

 

cost only 109$ (88€ !!) but is shipped not before March 8, 2018 !!
the specs are looking great:
Dynamic range: 125 dB
Frequency response: 10 Hz–100 kHz
THD + N: 0.0003%
SNR: 118 dB
Bit depth: 16, 24, 32, 1 bit
Sampling rate: PCM (44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384, 705.6, 768 kHz); DSD64, DSD128, DSD256, DSD512

and according to this pictures/links it has 2 !! ES9018Q2C-chips onboard..

same with the Sabaj DA3->there also 2 !! ES9018Q2C..

they also said this Sabaj D3 with 2 Sabres sounds better than an Cambridge AudioDacmagic V2, what i really believe because i had an Cambridge Audio Dacmagic here and it was well manufactured but by far not such a high resolution as the ES9018K2M by example; on the first DacMagic there were Wolfson-chips in it->see review at the forum->LINK

Topping NX4DSD->Thesycon XMOS-USB Driver Skysong/Singxer ES9038Q2M

so, 😉
because i have here really heavy problems in playing anything above 44,1/16bit due to buffer(and/or driver)-problems (on a raspberry the ES9038Q2M works perfectly) on a Skysong (Singxer)-USB-bridge and a ES9038Q2M (“Blue”) i came by chance across this Topping NX4DSD..

it has also a XMOS-XU-208 and a ES9038Q2M “onboard”; interesting is the specification:
“16/32bit 44,1-768khz + DSD512 (native)” and (whats more interesting):
NX4 DSD use costum driver from Thesycon”..
so, and thats the thing here..the “normal” Singxer USB-Audio Driver 4.36″ does not work here satisfying with a ES9038Q2M..
2 possibilities: we get in future an update for also playing on this ES9038Q2M without problems from Singxer or we can get some custom made Theyscon driver which matches “our” Skysong-Bridge+the ES9038Q2M..(any help here is really appreciated !!)
i´ve anyway attached here (and in the forum) the original Topping NX4DSD driver+manuals, which were btw. very interesting in setting up JRiver for perfect bitstreaming..(u have to use completely the ASIO-driver/interface..))
the Topping NX4DSD driver/manuals is the version V4.14..->NX4 DSD Manual and Driver V4.14->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=22

ES9038Q2M: just arrived, first impressions..

okay, 😉
today the “Blue”->LINK ES9038Q2M arrived; first impressions:
the pcb is much more light (in weight) than the ones before..


first musical impressions were:
wider soundstage..heavy “lock”-problems with the Skysong-XMOS-USB-bridge (guess its a firmware/driver issue (had to wait for an update or so); i use here right now a Samsung BluRay-player directly via coax), but absolutely more “pop”-tune, by far not so analytic, spacious, also very “flat”, cries really out for a “Muses02” OP-Amp..
there is absolutely something missing->guess it really needs its 15V..(this one is only with the 12V-plug)(but i could feed it maybe also with 15V->have to check/ask the seller) 
have immediately changed to “Muses02”; which i normally don´t do in fresh, new hifi-gear..(1-2 days “play in”-time)..
the HW-control with a 10k pot was also not so promising as expected..
i didnt test the 7 different filter; maybe the “devil” is there..
also it could be the pcb (and the soldered components itself); don´t know it at present->more to come..
Conclusion for now (and dont forget, this is “whining on a high level” 😉 ):
more “pop-sound” (originally the ES9038Q2M is/was made for handys/portables), not so analytic, spacious, needs apparently its 15V (+/-), cries out for another Op-Amp (Muses02 here), didnt test the filter right know; maybe its also the quality of the pcb/components..)(but that are only the first impressions, can change without notice 😉 )

(Update 2: so, got halfway at least a fairly accurate sound..(its not sooo bad/but for me it still sounds like plate/sheet 😉 )). This ES9038Q2M is very good with a Raspberry (via I2S); no clicks/pops/distortions anymore..very easy !! i use here now DietPi V6.0->tried “sabre-k2m”; didnt work..”hifiberry-dac”+”rpi-dac” works without any problems (but only up to 24/192; as said, “our old problem”; need modified kernel..)
as said, on a pi now very easy to handle, no clicks/pops etc..sounds very well but not soo “HiFi” as with the ES9018/28..somehow less distorted/cleaner in a way, but not so transparent/spacious as the “old”-sabres..could be a problem with the pcb/components on it..but for normal user this ES9038Q2M should be enough 😉
(by that for me DietPi V6.0 is at present much better/cleaner than Moode V4..its much “nearer” to the original recording; with this Dietpi u can fairly begin to work it out/fine tune))

(Update 1: (Win+Skysong USB-bridge)absolute no comparison to my “old” ES9018K2M+ES9028Q2M->they sound really much better, absolutely more Hifi; dont know what the main reason could be; maybe the pcb+the components; absolut “platy”; sounds like sheet/plate..
(Raspberry I2S Moode 4.0 (“hifiberry-dac”)); sounds really better on a raspberry !! absolutely easy to use; no more such horrible clicks/pops changing files/bitrates..as made for it 😉 ->used the hifiberry-dac “overlay”->absolut no problems up to 192/24bit, but no more (our “old” problem..) try to use some other overlays meanwhile..
settings->”Audiophonics ES9028 DAC” works too (in Moode V4->but only up to 192/24) 

Audiophonics: ES9038Q2M on sale (50€) + some techn. description..

so, 😉
for the european “Sabre-Lover” ;-), Audiophonics.fr has now also our ES9038Q2M “on sale”(50€)..(LINK)
seems its almost identical with our “green-boards” here;
they have also +15V DC plug on it, so i guess its PCB 1.04 minimum/upwards..

(User “Zek” (thx a lot!) here from the forum means:”..This board has an additional regulator for a 5V pin and an additional capacitor (in the middle).”(see comments).

by that there are also some pics with more technical details..(and as said, these “solder/unsolder”-thing)


by that, Audiophonics has also a toroidal transformer “Transformer Toric 30VA 2x15V” (LINK) on sale for only 17,90€ which seems to be ideal for our ES9038Q2M-boards..
(and a wonderful “wiring/installation”-tutorial/pictures for these torodial-transformer->http://forum.audiophonics.fr/viewtopic.php?t=389)

check it out 😉

ES9038Q2M: New version is out->V1.06 (Green)

so, 😉
because everyone visiting this site is really “on” new infos to the ES9038Q2M here are some pics and a description of the new “V1.06”-pcb-layout, i would call it the “Green V1.06“..($39$ Ebay/49$-41€ Aliexpress)
https://www.ebay.com/itm/ES9038-Q2M-DAC-DSD-Decoder-Support-IIS-DSD-384KHz-Coaxial-Fiber-DOP/132369245755?hash=item1ed1d2663b:g:ZrAAAOSw9p9aZ~xQ


they assembled also a DC-plug (here +15V DC) to it.. (to use it you have to short/solder J6 (is left above the plug from this view))
but the default voltage stays at DC +15V 0 -15V and u can still connect it directly to the board->”* It is recommended to use dual DC+-15V power supply to play board best results


the other difference i first saw that the 3pin-header (Volume) moved from “horizontal” to “vertical” (or vice versa)..The jumper row is now down to 5->

(maybe some other user can us tell the other differences in future)..
looks very nice 😉
