The SPL Phonitor One D Headphone Amplifier provides all the features and functions as the standard Phonitor One, but with the addition of a 32bit DAC built in. Now you can have all the high fidelity audio reproduction, crossfeed matrix, and high end DAC all within reach of home studios, audiophiles, and pro studios.
The SPL Phonitor One D Headphone Amplifier has two Burr-Brown OPA 2134 SoundPlus™ operational amplifiers provide the pre-amplification. These are specially designed for audiophile circuits and are characterized by extremely low noise and minimal distortion of only 0.00008%. Thanks to a true FET stage, the OPA 2134 achieves a slew rate of 20V/µs, making it a high-speed operational amplifier. This has an immediate positive effect on the liveliness of the playback.
The output stage of the headphone amplifier is designed as a push-pull amplifier in class AB mode. The bipolar transistors share the amplification of the positive and negative half-waves, which produces a higher gain and a higher output voltage than in Class A operation, where only one transistor amplifies both half-waves.
The Revolution​ in the headphone amplifier is the Phonitor Matrix, with adjustable crossfeed, thanks to which you can create mixes with headphones that sound the same on speakers.
