I have now a CD-player with the TDA 1541 and SAA 7220P/A tandem (it's a Sylvania CD1473 with a CDM2 transport). The conversion is done by 2 LM833.
It is possible to change directly the above chips (or just install a TDA 1541A) without changing the passives arround? I know that 7220P/A has a 5% DC offset so I was thinking to leave it there and don't change nothing in the 833 stage...
Is that wise? Or the 7220P/B ROM is that much better to worth messing with the 833 stage?
I don't have the schematics....
