The diamond tip with an elliptical shape allows better penetration into the LP groove, which significantly improves the processing of heights and prolongs the life of the needle. However, be aware that the needle should be replaced when you hear sound deterioration, as an old needle may damage the vinyl. The needle used in the Tonar E-Plugger is made of elliptical cut diamond, which is characterized by greater contact of the needle with the groove of the gramophone record and ensures the best sound reproduction in this price range. The T4P (plug-in) holder allows easy installation of the insert without the need to recalibrate the turntable. Reinforced Trap E-Plugger sensor body and aluminum support, made with extreme precision and attention to detail, ensuring a pleasant music experience.
