Introducing the Phonitor One, SPL have incorporated both experience and technical knowledge into the Series One. Two Burr-Brown OPA 2134 SoundPlus operational amplifiers deliver the pre-amplification. These are designed especially for audiophile circuits and are characterized by the very low noise and minimal distortion of just 0.00008%. Due to a true FET stage, the OPA 2134 reaches a slew rate of 20V/ s, making it a high-speed operational amplifier. This has an instant positive impact on the liveliness of the playback. Low capacitance film capacitors are also integrated in the signal path as bypass capacitors of the coupling capacitors, which guarantees a more precise transmission of the high-frequency signal components. The fantastic Panasonic Electric Double Layer gold electrolytic capacitors are used as coupling capacitors. These deliver the highest storage capacity of all capacitor technologies.
