Spl Phonitor One d
The Phonitor One d is a headphone amplifier offered by the SPL brand.
For preamplification, two Burr-Brown OPA 2134 SoundPlus operational amplifiers have been specially designed to meet the requirements of audiophiles.
Their remarkable performance results in extremely low noise and minimal distortion, measured at just 0.00008%. Featuring an integrated FET stage, these OPA 2134s deliver an impressive slew rate of 20 V/µs, making them a high-speed operational amplifier.
This characteristic results in dynamic and lively sound reproduction.
Additionally, to ensure accurate transmission of high-frequency signals, low-capacitance film capacitors have been integrated into the signal path, acting as bypass capacitors for the coupling capacitors. Panasonic "Electric Double Layer" coupling capacitors were chosen, known to offer the highest storage capacity of all capacitor technologies.
These component choices guarantee faithful and detailed audio reproduction, while preserving the integrity of the original signal.
