Guys, everyone has a valid point here. No, the Strain gauge does not reverse the RIAA curve as accurately as a good phono stage. But, it is capable of very good reproduction. In particular it's transient response is excellent so it's reproduction of percussion is first class. The sound it produces is more sharply etched, not as warm as some would like. If it has a major failing it is tracking ability. It can not hold on to the groove at higher velocities. It may miss track on highly modulated passages. It's distortion levels are also a bit higher than the best moving coil cartridges.
Having gone through a lot of reviews lately I have noticed that Lyra and Ortofon cartridges consistently perform at the top in terms of distortion levels and tracking ability. I have always liked the Lyra Atlas and the SL version would work super with a transimpedance phono stage. For myself I have narrowed it down to three cartridges, the Atlas SL, the MSL Signature Platinum and the Ortofon Versimo.
@drbond , If you fain interest in a $10,000 piece they will jump to attention. I am with you on VPI. Not my cup of tea.
