Hi Daniel,
Not completely sure what this means...
Is it that by setting J2,3,4 then DSD or PCM is selected automatically and that it for controlling the Dual DAC board?
What about filter setting for this combi?
Does J10,11 work for Dual board?
it means by selecting J2-J4 PCM/DSD is detected automatically for dual DAC board, I've asked him for filter setting, waiting for reply...
I made a version of the DAC is close to completion.
With ak4137 for some reason I did not like the sound. And it did not work at all sample rates. Perhaps somewhere I was wrong.
I stopped at USB DAC version.
Very influenced by the power DAC. As a result, in contrast to the photos, I have the power discrete Class A to OPAMP and DACs analog. And the Studer900 powered DAC digital part.
Power Studer900 analog part of DAC I removed, I liked the sound smaller.
Now I'm waiting tle2072 in power Studer900 to replace the 072. And as the replacement option ths4061 opa1611 in filter.
It sounds great!

PS. According to the experience - LT1963 does not go well in the digital part of the DAC! And especially in the analog part of the DAC!
They are often used, but the sound from them is not very good. Even 7805 sounds better. It sounds good digital part with Studer900.

Somebody tried to connect to the DAC for i2s raspberry mini computers?
They write that the sound is better than usb xmos or amanero.

730user: it's better but not because of RPi but because of Ian's FIFO reclock so if you add FIFO into your existing chain result might be even better than with RPi
Thank you for the clarification.
I read that the clock is not doing well Raspberry. So I do not quite understand the review was about a good sound.

Who knows. Are there not very expensive version of the reclock?
yes, sound from RPi I2S is pretty jittery and noisy that's why guys in Head-Fi using FIFO reclock between RPi and their AK4495 DAC, they aren't talking about good sound from RPi but from whole audio chain which includes FIFO reclock...if you look at the pictures (page 34 of that thread) you will see FIFO reclock device between RPi and that Chinese DAC... http://www.head-fi.org/image/id/9051987/width/900/height/900/flags/LL
Yes good news however it also just have to work in real life 🙂
Any one have that setup (AK4137 and Dual AK4495) working with filter settings?
Then it makes sense that they have the local volume control settings on the dual AK4495 card..
It works for me Nelso , changing filter settings on the 4137 has an obvious impact on the sound.
Anyone have experience with this board?
AK4118 digital receiver board SPDIF input switch IIS with IIS support XMOS sampl-in Amplifier from Consumer Electronics on Aliexpress.com | Alibaba Group
I'm wondering can I use it as selector between optical and waveio i2s?
Also I'm not sure about difference between online and standard version...

I have just finished my test setup with that board. I bought the online version with coding switch. That is the one with a potentiometer (built in push switch).
It works perfectly with the XMOS module from the same designer and the dual AK4495 DAC. You can change filter settings, inputs and volume. Just connect J10 and 11 on DAC to put it into online mode.
If you want to use Wave I/O you will need to connect it through the same connector as the XMOS card is using although I can't tell you if that will work as I don't have one to test it with.
I bought the DAC direct from the taobao seller and got the capacitor kit as it was cheap enough to not use if there was an issue. Here are some pictures of the capacitors side by side with the same models bought from Mouser. I cannot tell them apart and if they are fake then there is no way to tell by looking.
DAC sounds good and I am happy with it. Now I need to arrange a proper home for it.

ljufa: yes, you can use it as input selector
fluid: but this is AK4118 MCU board, right? it should work the same way as his complete AK4495 DAC board where MCU is programmed differently than in case of AK4137...
edit: he doesn't use fake components, this has been proved on all of his boards

Thank you both!
all sellers on ebay and aliexpress are very confusing. they all have the same description with different pictures and all describe online and standard mode but there is no option to chose online mode.
I also noticed some boards have Atmel chip some don't. Is this chip MCU for filter and volume control?

kukynas: I know this thread was started about the 4137 board but ljufa's link was to the 4118 board by the same designer which is why I posted about that one.
ljufa the seller on taobao ruizc is the source for these boards, the ebay and aliexpress sellers are just re-selling the boards at higher prices. The information in the description is just copied and google translated from the taobao site. You can choose different options on taobao but often not with the aliexpress or ebay sellers.
I think the different pictures are because there have been different versions of the board made at different times, if the pictures are good enough you should be able to see a date on the PCB which will give you an idea of which version they are selling. The MCU on the 4118 board can select between any of the inputs the board has and can change volume and filter settings on the 4495 and 4490 dac's from the same designer.
Do you have one the 4495 or 4490 dac's from this designer?
