@mijostyn I’m aware Replicant 100 is considered to be more ‘advanced’ than Shibata, but we must assume Ortofon selected this profile for a reason in their ‘statement’ SPU Century. Of course they could just as easily have picked the highest grade Replicant instead. Perhaps use of the Replicant combined with the other modernised design elements of the Century would have put it outside the desired SPU sonic spectrum.
Actually I didn’t suggest to go look for a more modern approach with an advanced stylus profile for high resolution. That’s not what the SPU is about. If that’s what the OP is after, there are other and much better alternatives, both from Ortofon and others (as you mentioned).
