    There will be others I'm unaware of..

    I have kept quiet, mostly on the basis that if you have nothing good to say, don't say anything at all, hoping that the issues would resolve themselves. But I cannot keep quiet any longer.
    The simple fact is that Allo violate software licenses! Specifically they are and have been violating the GPL. Despite the "weasel words" about how they "try" to comply, the fact is that you either are, or you are not in compliance. They are not! I would ask people to consider carefully whether they wish to support businesses who are violating licenses by purchasing hardware from such a company.
    I would also ask people to carefully consider which software distributions they use and support. There are distributions flouting the GPL. (And no, I don't mean piCore.)

    UPDATE.....

    Allo have made the plus driver available from their rpi-piano github repo.

    NB. Hopefully they will also add a repo where you can obtain the Texas Instruments DSP firmware for the 2.1/2 sub/active crossover functionality. Those files won't be under GPL, but should be under a license that is compatible with them being used by GPL'd code and also freely distributable without condition, other than they can only be used with a TI PCM5xxx series chip.

    The firmware is there now in this repo.

    I'm waiting for an update to the Piano DAC driver before I start building a kernel. The PCM5142 doesn't automatically switch to using a supplied external MCLK, the DAC's PLL will be used by default with the current driver.

    Kinda negates the main reason for using Kali/Piano in the first place...

    How do you figure that? The Kali/Piano situation in "fake" master mode, fed with Kali SCK, without the Piano really being the master and driving the Pi with BCK and LRCK, is the worst of all worlds..... But as long as the audiophools are happy with their audiophool beliefs...... Cool!!!!!!!

    Having the MCLK close to the DAC is accepted best practice, but that's not the point I was making. (FWIW I think it would be very difficult to hear the differences between either method anyway. Certainly with my ears, it would be a hard task.)

    The point I was making was that someone who had bought a Kali/Piano combination would perhaps expect that the Kali clock would arrive unmolested to the DAC. If it's passing through the DAC's PLL then that might have an effect. (That effect might be good or bad, or non-existent!) It's the same reason that some people are thinking about running Sabre DACs in synchronous mode with Kali.

    Just bought a Kali and not too happy with it, I wish I found this thread before!
    So if one would want a good reclocker for I2S, what would you advise? Is the hifiberry digi+ pro a better choice?

    Don't underestimate the Kali. It is functionally comparable to Ian's FIFO reclocker. That should say a lot.

    Keep in mind that there is a very respectable number of DAC chips out there that can not run in master mode, like all of the AK chips (AK4490, AK4495, AK4497, etc.) and the previous generation ESS DACs (9023, 9018, etc.).

    Since you've already bought it, why not just try it?

    thanks for the motivation speech, I am trying it and suffer from a small perk
    16 bit streams show alternating 16 bit and 24 bit recognition on the dac screen
    you can see it here

    I can't hear any defect but I'm wondering what that dac does in the background to reconciliate this and how it can affect the sound!
    24 bit streams are fine, so are DoP.
    When I setup ALSA to output 24 or 32 bit only (24, 24_3, 32 settings) it's the same, and DoP doesn't work anymore (depending on the settings)

    if I take the Kali out of the setup everything works fine

    I am already in discussion with the Allo support, for the moment they point me to a ground loop inside the player.

    Hi All,

    I am late to this Kali party.. has been using Pi/picoreplayer -> Hifiberry Dac pro+ I2S out -> Ian's i2StoPCM converter -> DIY AD1865 dac and has always wanted to try this Kali reclocker board for a long time till today. Board just arrive.

    I am playing with my new china taobao toy TDA1387 Pi dac https://world.taobao.com/item/538193...ucket=5#detail and it sounds really quite well but as usual the Pi clock is not up to standard. I figure that since this TDA1387 only uses 5V for the board i do not need 3.3Vdc. it also does not need the MCK as it regenerate its own MCK using the onboard 50Mhz TCXO. So i insert the Kali in between the Pi and TDA1387 board and it works nicely.. so much diff is the PRAT that it almost a different system.

    just sharing my opinion. Will be getting another Kali to for my AD1865 dac and throw away the Hifiberry Dac pro+ board since i am only using its Master I2S MCK and Kali already has it on Pin29.

    cheers

    sam

    Kali with ES9023 V3

    Hey guys,
    Can somebody tell me if it is possible to run Kali Reclocker with the audiophonics ES9023 V3 DAC? I think, the 9023 has it's own clock but everywhere i can read that much DAC "sound better" with kali.
    Greetings Daniel
