Default SAA7220 A/B/C any diferences for SPDIF out?

So there is a difference between the A and the B SAA7220 soundwise on the filtering, but is there also a noticable difference if one is only to use the SPDIF out? And is then also the C version helping (i know it is optimized or 32khz)?

Thanks!

I seem to recall C version less good, but don’t remember why.

From the SAA7220 datasheet:

Audio samples are available for digital audio output after attenuation, interpolation, attenuation and muting, but before filtering.

In this context digital audio output means DOBM, the S/P DIF output, so the different versions shouldn't make any difference if you're just using this output.

I'd agree to amc184's point, but from the datasheets one can't say if anything else what might affect the S/PDIF output was changed too. At least it wasn't mentioned.
As amc184 already mentioned, the S/PDIF output is generated before the digtial filtering section, so any differences in the filter section don't play a role.

Anyway, if using the S/PDIF for real time playback, it should be ensured that the receiving device offers really good clock recovery/reconstruction with jitter attenuation starting in the <5Hz region.

Thanks! At some point I might do a listening test to see if there is a difference at least between A and B chips.
