Hi.Who wants to trim RIAA given proper design done by stimulation or whatever.
For RIAA EQ, we got to make sure the Cs & Rs are dead accurate to the designed values. But noway we can get any without tolerances.
What else we can do to kill such tolerances assuming you can afford the most exotic parts once we measure out such ever existing tolerance.Trimming is the practical answer.
There are still many good designs of all-in-one loop FB RIAA EQ phonostages available, being simple & less active stages which I personally prefer.
Though split RIAA EQ may give better transient response, but it "may or may not sound better" as Allen once quoted.
