i2s converters to go with adau 1701 / 1401

Hi,

as there are 8 i/o s on the adau 1701 / 1401 I am wondering what kind of converters I could use for that and how to set them up.

Not sure if this is possible or advisable but as I2C control is working great now I am thinking of making a eurorack based small performance mixer. Having a basic 3 band parametric eq or maybe a 2 bans tilt eq for 8 channels and maybe with a second dsp acouple of effects would be awesome and pretty easy in case converters are not too expensive and quality is ok.

It doesn't need to be max quality. 16 bit 44,1 khz will do the quality of the ones on the chip is fine.

cheers
