Master DAC (Boss) for RPI
Everyone knows there are many master DACs/ RPI on the market. For one reason or other , we were thinking that hardware implementation was not right so we decided to design one ourselves. We want to achieve the best quality possible for a reasonable price.
PCM5122 IC
3 separate LPF..one for analog , one for digital and last for oscillators.
4 LDOs , including a lt3042 in the analog section
NDK oscilators (44/48Mhz)
Film capacitors in the analog stage .
Supercapacitor in the analog stage
Extra copper on the PCB for low impedance.
Samples received we are assembling and testing.

Is there a timetable for the release of the next KALI board? Can you you let us know the differences between the current K board and the upcoming one?
It is known by many that the PCM series of recently are less good than their ESS and AKM counterparts. Why choose for PCM parts then ? I think this was mentioned by others as well.
The BOSS is meant to be a good audio solution for an excellent price.
PCM IC fits this and we have a few good implementations for it. This is not meant to be hi end solution , rather a solid entry point in the RPI audio. With and SBC + Boss you will have an excellent streamer for (less) than 100$.
We will announce the hiend solution once we are more advanced.

They are 2 different solutions. If you opt for Kali + DAC you could always use it on a different (slave) DAC
I am yet to hear the BOSS...will update everyone once I do.
Yeap , like usually we will announce the testing giveaway ..

Differences :
Smaller board hat size.
Firmware upgradable
3.3 v pass through
I would estimate 8-10 weeks to release.

Thank you...
I'll wait with interest for the board release and the testers opinions...When I buy a Kali now, will it be compatible with this board? Or should I wait for a new Kali with 3,3v pass through and other fixes?
I want to connect a raspberry to my dddac with a clean i2s signal.

I am rather ignorant for the basis for using this third board, would someone kindly tell me what was the reason for it? The digi+ hat has oscillators on it and makes the Pi run in 'slave' mode to reduce jitter. What does this Kali do?
Would it work with the pi2design High-Performance Digital Audio HAT as well?
Coming Soon - Pi2 Design

Yes our team is at full strenght and working on it. We expect a bug free release (volumio and max 2 play first) very soon but I wont commit to an exact schedule
Board has been tested. We got sound.
Regarding the quality...we honestly think this is the best implementation of the PCM5122 as a master.
Next we are building 50 units MP and we will have about 20 to give away for testing. However due to Chinese new year we will get the PCB in about 3 weeks. Once received we will announce the testers.
