Bruce, I was wondering if the +/- 0,5db was from the RIAA, the
rest of the circuit, or a combination of both. (I don't have the
schematic.)

For public.

Stanley Lipshitz presented an AES paper sometime back. He
covered both passive and active RIAA types. According to the
article, some sources/manufacturers are up to 7% off. If
anyone is interested, here is a link/calculator based on his
equations. (I found my simulator was off by several tenths of
a percent.)

I would make sure the coupling capacitor next to V1 is plenty
large in value as its reactance "adds" to R1.

Just a thought that might help the public.
