Post Extract audio signal from PCM1792 !

Dear Members
I have an Original Electronics CD-2008F (cd player) that uses the good Burr Brown PCM1792. I want to extract the audio signal and use it on a tube circuit based on 6dj8 tubes, like those Mr Lampizator is using.
I want to avoid listening to music from 6 opamps that this cd player uses on its output & actually experiment with the tube like sound.
Does anyone know from which pins you get the audio signal from the PCM1792 chip ?
Look at the chip pinout bellow.

Off the top of my head i would give the pins labelled "out" a try

You still need something for I/V duties and obviously you would want it differential...

Not sure how well passive I/V works with the 1792.
