@cdsgames;
thank you for the fast support!
I just received the cable today.
Does someone can just confirm to me that it is the right polarity please?

Looking at the katana pdf and the black cable is on the left.
Did I received a wrong cable?
I'm a bit lost now...
That cable looks wrong to me. Brown wire should be near the word 'katana' on the right. Isn't that how the manual shows it?

Forget that. Most of us are more then happy we finally got rid of that extremely annoying USB interface for audio after years of suffering.
Most of us spent 100s of $ to clean that messy interface up.
And don't tell me you'd like to run DSD512 or 768kHz. Or anyone would!?!?
These rates are nonsense and just used for marketing purposes. 99.9999% is still
44.1.
Enjoy that I2S HAT. It IMO can't get better than that.
The final noise of the Allo USBridge is lower than the noise of a battery. And maybe Allo has a signature version of it in the pipeline like the signature version of the Digione.
With an USB input Katana you can select which sounds better to you or better fits into your set-up.

That USB bridge is the consequence of that messy USB interface!
Just another gadget/solution trying to cope with it.
You just don't need USB. Inside the DAC after leaving the USB interface chip you
go I2S again anyhow. That doesn't make sense. You can have I2S right on the Pi.
You know certainly better than me that RPi I2S is far from perfect.

RPi dacs are fine for listening to music.
Not necessarily so fine for things like editing music or video, or just for use when watching video. When real time playback from USB, SPDIF, TOSLINK, AES interfaces is needed, then what? It seems understandable some people would be asking about such things.

Nope. I don't know that.
What I know for sure is that there are different ways of handling I2S.
And actually it's been Allo who has shown how it works best!
USB still sucks!
Another try??
OoohKay. It's getting weird.
You just don't get what I am talking about here.
I never said there aren't any good USB Audio """solutions""" out there.
I did say it takes major effort to cope with the issues around the USB interface.
For a period of at least ten years the entire high quality audio industry failed
to eliminate the USB associated issues. Things did get better over time tough.
However. These USB related issues still exist! Otherwise we wouldn't need a Allo USB bridge, USB Regen, iPurifier. isolators, asf. asf.
If manufactures would build DACs that'd be able to cope with USB properly, we'd be able to use a RPI USB port as-is. It doesn't seem to be possible though. Yep. USB is that bad.
Many issues are bettered by going straight I2S.
And. I really do not need DSD512 @ 370MByte/minute as a trigger to drive me back into that mess.
Enjoy.

If you ask me whats best from a tech point of view...i2s without a doubt.
It was designed for audio and especially with master mode i2s is almost perfect (since MCLK comes direct from a clock thats next to the DAC ic. You cannot lower the jitter more than this particular architecture
However people seem to enjoy higher sample rate and DSDs and on most SBC /i2s its not possible , enter the USB solution
Its convenient , its fast but I seen some tests and its not perfect in asynch mode. (losing some bytes..??)
I think best bus depends on what you value.

Hi Cdsgames,
Is there plan from allo enhance some distro other than volumio? think volumio is going on hardware path..
Hi,
Katana works very well with Moode.
You may even play DSD256 DoP with some versions.
