I own an old dac with an 13W3 I2S input, I tried to search online to find what pins are used in the connector so I could make a wire for it to no avail.
is there a way to know what pins are used so I could make a cable? maybe I could look at the circuit board?
the dac I own is the muse model two plus. (cs8412->df1700->pcm63)

CS8412 is not I2S. Try trace back the connections from the cable pins to the chip. Is there any input ransformer? It could be SPDIF interface.
the cs8412's job is to convert the s/pdif inputs to I2S for the df1700, which then converts the I2S to an output that the pcm63 can read.
by connecting the I2S input I will be able to bypass the input receiver (cs8412), and will be connected directly into the digital filter (df1700). which is why I want to do so.
maybe I will even change the df1700 in favor of a pmd100 later, but first I got to figure out what to do with the I2S input.

ok so looks like I was right, do you think something like the douk u2 pro could be used if I find out what the I2S connection pins are?
that much I know, the muse model two uses a 13w3 connection and not hdmi. I just need to figure out the pin so I could make a hdmi->12w3 cable for my dac and whatever DDC I will choose.
my question is what are those +/- connections, the df1700 doesn't have those, does this mean I won't be able to connect modern DDC'S with such +/- to my dac?

+/- is most likely balanced LVDS. I guess you need a receiver that translates LVDS to TTL (3.3 V).
do you have ideas for what I should look at to find out if my dac can be connected to modern ddc's via I2S?
DF1700 required from I2S just 4 signals: WCLK (pin 28), BCLK (pin 2), Data (pin 1) and MCLK (pin 6).
But I2S must operate in RJ16, RJ18 or RJ20 mode, depend of how DF1700 is configured in your board.
These modes may not be available in the modern sources.

is there a possibility that there is a converter (rj16/rj18/rj20) before the df1700? so that the I2S is actually wired with those +/- and just converts them to the df1700 pins layout before connecting to it?
Theoretically it is possible to do this (it requires some kind of logic "glue", such as shift registers), but I don't know where you can get it ready-made.

I can probably open up the dac and look inside, will some pictures of the digital board will help figuring it out?
13W3 was the original I2SE connector. A Google search using the terms 13W3 and I2SE should find it.
was there a I2S 13W3 standard back then? because if not the 13W3 I2S inputs could differ from brand to brand.
my question was more towards rfbrw, but is it possible to send you pictures of the digital board?
if you could tell me stuff about how the digital board works based on its look it will be very very helpful.

You can share the pictures here, maybe is will be possible to see something.
