Lyra SPT (Stylus Performance Treatment) assists tracking and minimises damage to your records and cartridge by keeping your stylus scrupulously clean.
Lyra employed extensive listening tests during the development process of SPT, with the express purpose of improving the sound of your phono cartridge. Not only will it work well with Lyra models, but you will find that it offers a significant sonic boost to other high-performance cartridge designs as well.
SPT should be applied in a small quantity with the accompanying brush each time it is being used. However it has been designed so it can be used frequently, even after each LP record side of play, or as often as you deem necessary in your particular environment.
