and so, because i had great problems/was not possible to order from TaoBao direct, i got today a free 8$ coupon from yoybuy.com..checked it now for the first time and will then report here any info.. 😉

ES9038 Q2M: Driver/audio settings in MoodeV4Beta/on Dietpi..

so, 😉
many thx to „Blackbear“ over at the Diyaudio.com-forum http://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board-10.html
and because of min. 80% !! of the visitors here on the blog a searching for ES9038Q2M-related info, here are some results on his „research“:
In MoodeV4Beta on Dietpi he uses the „Audiophonics ES9028Q2M„-audio-settings..(for the ES9038Q2M)

„..Hello, in dietpi i had selected no driver = just left rpi-2835 (I left it without change after installation…), but in moode driver selection i choosed audiophonics 9028q2m, so it is strange that Moode takes control over dietpi driver (now I am thinking about it…) ? but it works, also tried to switch in dietpi config onto i-sabre-2km driver then restart and no sound so then i had to go into moode driver and to select audiophoincs 9028q2m, tehn reboot and it works again…strange..“

greets for now..

New Pics III.: ES9038Q2M

many thx to „Janos_904“ over at the Diyaudio.com-forum->http://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board-3.html?s=b2de8136b3f09c3da9f11088b3614efb
there is a new pic + description:

->“My board have just arrived ! I was surprised, because of the fast shipment and the very good quality. It is so much better than the cheapo ES9018K2M board. There are good quality smd components, and the module comes with Nichicon FW (yellow/black) and Elna RW3 (brown) capacitors. The consumers of the DAC chip are isolated well (see red circles). There are plenty of upgrades available for DIY-ers! I installed a Superreg instead of the KA7808 reg, and +/- 15 V superregs for the opa. The sound with 3 superregs using coax is good, full with live, and detailed even with the stock JRC5532DD.“

New ES9038Q2M-forum link + other pictures (things)

okay,
here´s another, fresh, ES9038Q2M-forum-link: http://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board.html

by that i´ve found some further, interesting pictures concerning the „targeted“ DIY-DAC !! 😉

first, i´ve found another ES9038Q2M-chinese-board with a 15V (DC)-plug->

second here´s also again a little „picture“-description“ how to connect a „DSD„-Led to a XMOS-Usb-Bridge.. 😉

and third, heres a picture how to connect a bluetooth-receiver-modul (CSR-8670/8675) directly to an ES9028Q2M (in this case) via I2S..

New ES9038Q2M´s out (Part II.) + first reviews..

okay,
here are first reviews on the ES9038Q2M-chinese-Boards:->http://www.diyaudio.com/forums/digital-line-level/297351-chinese-es9018k2m-i2s-dac-post5240556.html (many thanks to „Drone7“ there.. 😉 )

->“First impressions… I am quite surprised… My Diyinhk 9018k2m with 3x custom power supplies is bested by this 9038q2m using a single 15+-0-15- supply. (plenty of opportunity here for upgrading )
It does not have the ‚clinical‘ presentation I associate with ESS chips… and seems warmer and fuller yet without sacrificing detail.
Resolution and soundstage is noticeably better than the 9018k2m .
I have wired a 50k audio taper pot and can adjust volume. Not a big range but enough to use as a ‚digital controller‘ direct to a power amp.
Using a rotary switch to change inputs. No switching noises ! Very smooth operation.
Will try switching filters next but can’t see the need really. Who changes filter on a track by track basis? .
I would rather listen to one for a week then try another and eventually settle on a preferred filter then leave it jumpered.
Inputs tested …Usb to i2s, optical, and coax all work.
Downsides ?
… so far no direct i2s driver to be found..:-(
I am using a usb to i2s (raspberry pi player) interface and this works ok mostly… lock not achieved unless the dac is switched on while the Pi boots. If it is on first the Pi does not recognise it.
If anyone finds a dtoverlay for this I would be most interested…“
Maybe on the drivers AUDIOPHONICS I-Sabre DAC ES9028Q2M Raspberry Pi ?
Tried that . Does not work..
I recall reading that the 9038Q2m is equivalent to two 9018k2m so drivers may be very different..
you are not getting noise or glitches between tracks or on changing sample rate tracks – even on high res?
Nope, no noises,clicks,pops or otherwise. Plays smoothly when moving from 24/96 to DSD to 16/44..
Using usb to i2s.(XMOS USB U8->https://www.ebay.com/itm/XMOS-U8-USB-384K-32B-module-I2S-SPDIF-output-support-DSD-for-es9018-DAC-hifi-amp/282706307492?hash=item41d29be9a4:g:bgsAAOSwoVNZ7xy~


3pole 4position switch.
Position 1 connects as if jumper J2=optical spdif in,
position 2 as if jumper J3=coax spdif in,
position 3 as if jumpered both J2 & J3=i2s in,
position4 no connection so acts as mute.

It matters not which pin the black wire connects to on that side on the board header as they are all shorted to each other.

New Board:


(Board power supply: AC 15-18VX2 (3 lines) + AC 7-12V (2 lines))
