There isn't schematic it's only a low pass filter like posted before, I use Amanero for USB-I2S so output pins:
Pin number 3, I2S DATA/DSD1, Out, Data stream LVCMOS 3.3V 47ohm, channel LEFT
Pin number 5, I2S FSCLK/DSD2 Out, Frame sync LVCMOS 3.3V 47ohm, channel RIGHT
The noDac it's only for DSD, so you only can listen DSD music and have a player that converts all PCM files to DSD files.
Attached an image with other LPF for reference and my filter without output coupling capacitor that value will depend of load (pic don't show the cap because I was using a step-up after the LPF).
Enjoy and welcome to DSD paradise.
N.B. I also dislike flip flops because kill the music so I accept to listen a residual noise like when you play vinyl.

I’m not sure of the exact value, but it would be equal to or less than R13 at 332R.
I use HQPlayer, so can output DSD. This might be an interesting experiment, though I worry a little about damaging the JLSounds board.

I guess is higher because my Intact Audio AVC doesn't sound as good as with low impedances.
In place of AVC I tried with a passive attenuator ladder configuration 100K Dale RN resistors with Elma switch and improved a lot the sound quality.
