One last thing…remove that audiophonic PSU…use only 3a PSU to feed Kali , RPI and DAC…
Attention the 3A PSU has to be connected to Kali (not RPI)…since Kali barrel only accept 3A (rpi micro USB its 2.5A I think)
Let us know if it works
…its a problem… The only psu with power jack i have is Audiophonics. Rpi psu has a micro usb… so, i think that ill wait for my new puchased Allo psu…
Im pretty sure that the problem will be solved…
Tnx Michelangelo and Allo… ill post result of my tests for others users…
Yes, 5.05 volt out… but maybe the problem is the Audiophonics psu.
Many products they sell are Chinese (you can found the same product in AliExpress Market). I dont say that Chinese products are garbage, but maybe 3A… are not 3. If Kali accept only 3A (real) the problem maybe is the psu. I dont have another psu with dc jack so… ill wait this week to try the Allo psu when delivered. I assume that Kali MUST work with and without jumper so, ill try with a fresh install and after that I’ll tell you the results hoping for your help if needed… [emoji4]
Does it matter what rpi I use? Is there any difference between how long it takes to load album art, sound and so on…? I have a b+ a rpi2 and a rpi3.

Faster device = less time to fetch and download albumarts
Hello,
here is my plan, let me know if i went too far
SMPS (5V, 3A) => CAPACITANCE MULTIPLIER => Kali (on RPI2) => Piano DAC
SMPS (24V, 5A) => CAPACITANCE MULTIPLIER => AMP => speakers
i want to add a display also, so the questions:
1- what do you think about the setup?
2- will i be able to add a display when Kali is mounted on the RPI?
3- will i be able to use jumper wires in case i wanted to separate the boards to make room for LCD connections?
4- how do i identify the Kali units with the pause-loop bug?
my CAPACITANCE MULTIPLIER(s)/Kali/Piano are on the way.
many thanks!
Hi,
I’m just received my Kali+Piano (v1.1) Bundle.
I use fresh intall of volumio 2.118 .
If i choose Playback Options / Dac Model ; Allo Piano i’haven’t any sound
The playback is running and cat /proc/asound/… is ok
If i remove Kali, all is ok.
I need to chose Playback Options / Dac Model ; RaspiDACv3 to have sound with kali …
So no change since October ?
But for me there is a bug when i chose ‘Dac Model RaspiDACv3’ with kali : each time i stop/start new song i have a call trace error in dmesg :

@llevet
Have you tried using the IQAudio DAC Plus setting?
Hi,
Yes i use it. I have see on the forum that it work well with. And no error in dmesg.
Michelangelo try to resolve the issu on the firmware with this release (Piono 2.1 thread on the forum).
Thank’s for your response.
Ludovic.
Hi guys,
I intend to build a dac based on RPI (either B+ , 3 or Zero) + Kali (22/24) + Dual WM8741, but I read somewhere, that the Kali 22/24 is not working with raspberry pi. Is that true? Because it doesn’t make any sense to me, that if the clocks are running at half speed it will influence in any way the pi… Logically it is a one way direction from PI to KALI and regardless of what is after the PI it shouldn’t influence it…
Could somebody shed some light on this…?
The reason I’m talking about 22/24 version is that the WM8741 accepts as maximum MCLK 38.462MHz according to the datasheet. Would it work with 44/48 MHz version or is there maybe an easy workaround? Are 22/24 versions available as new or only as used?
Nobody?
Then I’ll try a simpler one:
What is the master clock output frequency of the Kali? Is it directly the selected OSC frequency or is a fraction of it?
Hi Tom. A few posts ago i have read that you tested Kali with the ES9023 V2 from audiophonics. I own the V3 Version and i am planing to get Kali, too.
So can you hear big difference with and without Kali? I am not sure what to do. Also i am thinking about to buy Allo Piano and Kali and sell the audiophonics dac.
Greetings Daniel
Go for the Kali and hear if the improvement is to your liking. The Piano uses a different dac chip and is implemented differently and will probably sound differently. If it is better for you is up to you. First try the v3 with the Kali.

Thank you for the answer. Just some questions before i buy the kali:
- Which version do i need, the older or the newer one? I think the newer one goes to 384khz, but the ES9023 delivers only 192khz. So i think the older one?!
- The DAC has an own power managment. I feed it with 7.5 Volt. How can i deliver power to the Kali? The Kali has its own power socket but i can feed it with only 5 Volt.
Greetings Daniel
Get the newer one as the Kali will work with all these rates.
I would suggest to order the Kali powersupply with it as the Kali needs power anyway. And if you change DAC in the future for whatever reason, the Kali can power it as well much better than the RPi can. The Kali will also power the RPi so you do not need a seperate RPi power supply.

I have been very happily using a Kali reclocker with volumio and a raspberry pi 3. The DAC being a homebrew NON-OS TDA1541A with passive i/v and a valve output stage.
My music FLAC files are accessed through Minimserver UPNP which is running on a banana pi (as it has a SATA interface). I have to say the sound is excellent and overall I am extremely happy.
However, I have a couple of questions:
-
If I stream to music from minimserver to my I phone, the music starts and stops almost instantly. Whereas if I stream to Volumio 2 with the Kali there is a considerable delay before the music appears. Is there a way of shortening the delay or is it a case of simply needing a SBC that is faster than the Pi?
-
The second question I have is; are there any changes that should be selected within Volumio to optimise the sound for working with the Kali board?
Thanks
Ian
Hi…i am a new user here. In my case Volumio setup I am using a Hifiberry Digi+ to feed my external DAC using a coaxial SPDIF signal.I assume that my DAC (as most external DACs) uses the spdif signal for its clock signal. Is that correct?And if so, could there be a benefit in adding your reclocker in between to improve the DAC input signal?
On q1; I think the delay is caused by the fact that Volumio uses a buffer from which it plays its music. So when hitting ‘play’, the buffer has to be filled before playback starts. You can make the buffer smaller, so playback will start earlier. But there is a good reason to have a nice buffer as through this buffer Volumio will almost always have the music data available even when there are short communication hick-ups which is not uncommon on wifi or other wireless networks. When not using (or very small) buffers, playback will suffer when the music data falls behind. It is most likely not your Pi (assuming you are not using an old Pi, but a Pi2 or 3). Also, the Kali has a buffer of a few milliseconds which it needs to perform its reclocking magic. Therefor a small delay around 1-2 seconds is not strange.
On q2; as far as I am aware, the Kali is completely transparent to the Pi and the Dac and no configuration is needed (or can be done anyway).
Yes to both questions 
But…
The Kali is meant to be transparent on the I2S signal coming from the Pi so in theory your Digi+ should benefit from it. But I have read reports that the Kali and the Digi+ are not compatible which each other.
Alternatives:
- Replace the Digi+ with a new(er) board as these replacement boards are not much more expensive than the Kali
** There are new version of the HFB Digi(+) like the Pro that have its own reclocking features on board
** There are other boards like the Allo DigiOne that are specially geared to producing a very good SPDIF signal (has its own reclocking and other features as well) - Put a reclocker further downstream like the iFi SPDIF iPurifier
** No need to replace your existing setup
** Can be used also in other setups, for example when using a Chromecast Audio or other SPDIF output devices
Also something to consider to improve the SPDIF signal is to clean the powerfeed by feeding the Digi+ with its own very clean power using a good PSU.
Is Kali compatible with IQAudio DAC pro? Thx.
