The 78 RPM stylus for the Ion iCT04 phono cartridge features a 3.0 mil polished diamond designed specifically for the correct tracing of the wide grooves of 78 RPM records. It results in minimal groove wear and accurate rendition of voice and music.
A very common misconception is that you can use an LP stylus for playing 78 RPM records. This is one quick and sure way to damage the 78 RPM record grooves. To maintain the playback fidelity of your 78 record, you really need to use a stylus designed for 78 RPM records, otherwise with just a single playing, you could ruin the fidelity of the record grooves. Moreover, the LP stylus is much narrower than the 78 RPM record groove hence the tip will slide to the bottom of the groove where debris has collected for many decades. This results in extraordinarily high-surface noise.
