"The TI PCM2901, I am told by a Watsonville rep, was used in the K3-S."

Thanks.

The PCM2901 and PCM2903 appear to be be very similar.  The only obvious difference I found is in support of S/PDIF.  It was interesting to see that the shared data sheet shows even the latest version of the PCM2903 is not recommended for new designs.

I didn't see anything that suggests the performance of the PCM2901 is better than the PCM2903 but I never was good at "spot the differences".
