Our S-300i is a integrated amplifier which taps audio from the fully differential output included in the internal DACs of iPods and maintains this balanced signal throughout the circuitry and it features direct coupled design & fully balanced preamplifier circuitry for the noise reduction. Our direct coupled circuitry eliminates impact-robbing capacitors from the signal path and an elegant & custom-machined level control adjusts volume.
