Audio Technica's comprehensive redesign of the AT33 Series introduces substantive improvements in tonal character and structural integrity. The introduction of die-cast zinc construction at the cartridge foundation effectively suppresses unwanted vibrations, enhancing midrange and bass articulation across your vinyl collection. The True Mono dual moving coil mechanism operates independently of vertical groove noise, responding exclusively to lateral stylus motion and producing exceptionally transparent monophonic playback with reinforced low-frequency extension and minimized surface artifacts. This specialized configuration performs equally well as a dedicated mono solution or as part of a stereo turntable setup, granting audiophiles access to the complete harmonic palette of their records.
