RIAA Equalisation for Displacement-Sensitive Phono Cartridges

Gary’s interest in RIAA equalization for displacement-sensitive phono cartridges has been piqued in recent years by the revival of interest in strain-gauge phono cartridges and the claims made for them regarding playback equalization. Strain-gauge cartridges were once manufactured by Panasonic and Win Labs. In recent years new displacement sensitive cartridges have come on the market, where the required ‘RIAA’ correction is unusual or, some claim, not even required. Those claims have prompted his investigation.
