here are btw. some new ES9038Q2M-chinese-board pictures..
the board-layout seems to be changed to 1.04 and you can see how you can apply a input-selector switch to this..
(connected to JP2 and JP3; as described earlier and again on picture 3)
(basically you can do this too with another selektor on the other pins, so that u can change the different digital filter settings..(FIRs))
(Beware: according to some sources 0=Connection , X=Disjoin !!!)
6000$ -> Mirus Pro -> Link
(they use 2 * ES9028Pro-> >130DB THD..)
(II. in the „old“ Invicta they used 2 * ES9018 and with AD797-opamps btw..)
this time i changed the onboard NE5532 from the ES9018K2M to Muses8920 and the result is:
first, absolut no comparison to the OPA2604 (in any case to those i had here)->they were really bad..
These Muses8920 have a great musicality, and a very fine resolution but at present it lacks of something (in comparison to the NE5532)..
(so, here i have stop for a moment, because i have to re-check them in a few days..)
more to come…
absolute fabulous !!
Moode-Audio Ver.4 Beta 6 is now available via:
problem is u have to compile/set it up more or less by yourself..
U only get some moode-audio-files (.zip) but has also to download debian-stretch-lite and make/bring it via a lot !! of shell-commands to work..
For me it took about 4 !! hours..
so for this reason, i decided it to upload the SD-Card-Image (about 2.5GB) to „Google-Drive“ (for other, not so „Linux-Enthusiasts“ 😉 )->use „Win32DiskImager“ or similar to write it to SD-Card..but be careful its under the GNU GPL-free license !!
Debian-Stretch-Lite->LINK (orig. Raspberry.org)
(Update: thx to someone over at the MoodePlayer-Forum Link here is an Image of Beta9 at Google-Drive-> (2.4GB compressed to 918MB)-> Link (Google-Drive)
(rem.:this is the so called „BASIC/no extras“-Installation, without wiringpi,rotary-thing and without additional components (u can install them then by yourself)
so, Settings for the ES9028Q2M (for now):
got only „RPI-Dac“ to work; but limited to 192khz as said..“Hifiberry-DAC“ only works with mp3/: ->flacs->horrible noise..(if in 16bit->try to set min. 24bit in „MPD-Settings“)
try to check more options->post it then here..
Installed squeezelite too, and for the first time, NO loud clicks by switching from 16/44 flac par example to 24/96 or 24/192..
hi there, just read here:->
„it seems that there is already an MCU fitted (ST’s STM 8S103F3) programmed to allow access to some of the es9028 internal hardware functions (volume etc)…“
guess on the „newer“ ES9028Q2M´s (layout „2017 04 09“) there is this STM 8S103F3 and there is also a 4 pin header (5V+, SWIM,GND, Reset) to program/read out them..(SWIM-interface)
so, now is the question if someone has ever read out that eeprom (on these boards) or re-programed (and with what ?)..
any comments here concerning this topic are really,really appreciated !!

This product is finished board, using the latest audio DAC ES9038 Q2M as the core design, comprehensive deep software control optimization, PCM DSD switch no sonic, 3 groups of inputs can be simultaneously access, jumper smooth switch
Product features are as follows:
1. Onboard MCU MCU, used as a pure IIS / DSD input DAC board
2. Support coaxial and fiber input, support PCM44.1Khz-192Khz / DSD64 hard solution
3. Onboard to provide volume control interface, connect a single 10KR or so potentiometer that can achieve volume control.
4.ES9038Q2M better than the previous generation ES9028Q2M sound, thicker thick flow, direct support for coaxial fiber DOP, DSD direct solution, 129dB DNR -120dB THD + N quite excellent.
5. With the board default 5532DD op amp, use the transport seat to facilitate the customer to upgrade the fever of the op amp
6. The use of imported high-precision active crystal
7. The use of high-quality gold-plated RCA, metal shield headphone output interface
8. Carrier signal lock indicator and DSD signal indicator
Coaxial: PCM44.1K-192K 24BIT / DOP DSD64
Fiber: PCM44.1K-192K 24BIT / DOP DSD64
IIS / DSD: PCM44.1K-384K 32BIT / DSD64, DSD128, DSD256
Output: Dual-channel single-ended RCA output, 3.5 headphone monitor output
Power supply: regulated DC voltage double 15V or regulated DC voltage single 15V
* It is recommended to use dual 15V power supply to play board best results
(more information also here (about the chip)->http://bbs.hifidiy.net/thread-1257220-1-1.html)
first, an 3.3V/5V Power Supply Module:
(Attention: cable colors not matching perfectly->just for illustration !!)
Breadboard power supply module, compatible with 5V, 3.3V, apply to MB102 breadboard.
Two road independent control, can switch over to 0V, 3.3V, 5V.
On-board two groups of 3.3V, 5V DC output pin, convenient for external lead use.
Input voltage: 6.5-12V (DC) or USB power supply
Output voltage: 3.3V / 5V (switchable)
Maximum output current: < 700mA
Dimension: Approx. 5.3cm x 3.5cm / 2.1″ x 1.4″
10 Pieces ->5,19€ (incl.shipping) !! on ebay-> LINK
wonderful for external (USB-Powering) 5V Hifi-components, such as the ES9023 Board above or par example these things-> (and you can use 2-3 or more components powered by this breadboard power supply !!)
and second such an „I2S“-Doubler; also absolut wonderful and can also be powered via this Breadboard/5V !!
Aliexpress 5,50$ -> LINK
(Remark: unfortunately not tested here; the breadboard power supply just arrived but havent found the right male-male usb-cable yet, so i have to wait, but i would (will) have had soo much fun with it, i guess 😉 )
