Out of 2 TDA1541A S1 I selected one with very nice and pleasant - warm sound, but not enough low end definition. The other TDA1541A S1 has the same sound character as TDA1541A I use at the moment, good low end definition while still managing to be subjectively pleasant on the ear.[/B]
Very interesting - all 6 TDA1541A chips sound different, and they all come from the same batch![/B]

Are we supposed to ask what information that is ??
FWIW I have used S2 and found it to be the absolute best of the whole bunch. Very different from S1. A bigger difference exists between S1 and S2 than between standard versions and S1 in my ears.
I still have one unused S2 that will be used in Pedjas DAC. I am curious how it will sound in that configuration.
Did you measure your S2 ?
