PlasticIsGood,
look closely the timing chart ,
in the DATA L row of I2S 8fs mode , it is annotated L1 R1 L3 above the chart.
and DATA R have R0 L2 R2 annotation.
it means the DATA L contains odd number of samples of 8fs signal and DATA R contains even.
one DAC of CDP-507ESD feeds the DATAL and WS/APT (and BCK),
the DAC outputs L1 and R1 at the next BCK from negative edge of WS/APT.
another DAC feeds DATAR and LE/\WS, then outputs L2 and R2 at the next BCK from negative edge of LE/\WS.
this is just the mechanism you presumed.

Thanks, Shinja! I felt there should be an elegant solution.
I've never needed to understand a timing chart before, but in this case there's one pair of opposites too many for my head to grasp without an illustration.

This idea went into Cambridge Audio's CD2, CD3 players and DAC3 (the original 80s one) didn't it but at x16 OS with 4 x 1541A chips? Or was it a different arrangment?
Have an advert somewhere that describes the arrangement in simplistic terms.
Stan Curtis says he spent time matching 1541As so that they were a closer match to each other than Philips provided with the S1s (probably custom matched Rs were too expensive to outsiders too ).
