Comparison with general purpose chip resistors: * Production Method: Strictly selected materials are used for high quality sound and the production is controlled at specialized processes. * Performance: The general characteristics are the same as standard resistors, which makes it possible to be used for existing models. * Sound Quality: Heavy bass echo, high frequency sound, resolution, clearity, etc. are improved.
