Yup. When it was first used for external audio connections, the connectors used were 5-pin DIN and DB-25 (for I2Se).Once again: I2S is not a device to device connection standard.

I have not read about WS so far but been reading separate clock. Maybe I missed. However, as there is no written standard that I can find so far I asked if WS is ignored. If you know of any document that defines/explains how I2S as it is used externally by some manufacturers please post. Otherwise everyone is in the dark, I expect you as well.I don't understand the question. The clock (SCK) defines when the data (SD) is valid. The word select (WS) is needed for the receiver to know where the sample boundaries are. If either one of these three signals is removed, what remains is useless. I don't know that anyone is ignoring anything.
Some of the manufacturers publish the pin assignments they use. Here's an example from Audio-GD:I have not read about WS so far but been reading separate clock. Maybe I missed.

It is a shame that they haven't got together and created a standard. This is not the right way to treat a consumer!Some of the manufacturers publish the pin assignments they use. Here's an example from Audio-GD:

I assume SCLK here is the same as SCK in the I2S spec, SDATA is SD, and LRCLK is WS. MCLK would be the high-rate clock I mentioned earlier as being required by many DAC chips.

Using the Pink Faun 12S Bridge, as it is called, is an add-on card for a PC. Think of it as something like the Sound cards from Soundblaster or Asus. First it has the advantages of not converting to USB and the back to I2S in the DAC. Though to be fair these digital to digital conversions are all benign. Second, my understanding is that the signal is balanced from the get go.Maybe I'm completely missing the point and totally stupid but...
The XMOS USB interface in a USB desktop DAC converts USB > I2S that get send to the DAC chip.
So what is the benefit/added value of adding an extra box that you connect USB from the computer and outputs I2S through HDMI cable to the DAC?
I2S supports PCM 1536 and DSD 1024, is that really such a big deal compared to PCM 786 and DSD 512 that most XMOS based DACs support?
That isn't an advantage.First it has the advantages of not converting to USB and the back to I2S in the DAC.
It does indeed:

Compared with the figure from Audio-GD, this has the opposite polarity on two of the differential pairs (red labels in the figure). It also has some additional signals. For extra fun, there is apparently a setting to switch the polarity of those two pairs.

Unfortunately, the high price is a fundamental problem and difficult to understand for end customers these days.Looked at the product page of the Pink Faun 12S Bridge.
Personally I don't see anything that would justify the €325 price tag for the basic version, with upgraded clocks the price goes even up to an incredible €1575
I have the feeling that the XMOS interface in my DAC is feeding the DAC chip an I2S signal that is just fine, especially since there's some extra conditioning before it reaches the chip. I'm sorry but I don't see how/why this Pink Faun would improve my setup.
Excuse my ignorance but... what exactly is a "balanced digital signal"?
And how/why will this make the Pink Faun worthwhile?
High price to whom? To all end customers? What is a high price for one person is a cheap price for someone else.Unfortunately, the high price is a fundamental problem and difficult to understand for end customers these days.
Yes of course. It's always a matter of your attitude towards something, your priorities and your own possibilities.High price to whom? To all end customers? What is a high price for one person is a cheap price for someone else.
And, of course, whether you are willing to pay the price for the last 2%
Excuse my ignorance but... what exactly is a "balanced digital signal"?
So far I have not read anything that shows that it does anything meaningful.whether you are willing to pay the price for the last 2%.
It is not about myths or beliefs.It gets "split" into two differential signal to get high common-mode rejection? Can't really imagine it makes any difference (no pun intended).
The nice thing about AES is that it lets you have longer cable runs. It does not remove a mythical layer of awfulness
Hope it was clear that this was only meant symbolically. It can also be 0.01%.Ich würde das näher an die letzten 0% legen
... it could also be worse than all other solutions. I don't know as I haven't tested it. As written in the previous post, whether or not it has an advantage can also depend on external circumstances.Bisher habe ich nichts gelesen, was zeigt, dass es etwas Sinnvolles tut.
In dieser Hinsicht ist das Produkt unabhängig vom Preis teuer, da es nichts tut.
