Crafted with discerning audiophiles in mind, the SPL Phonitor One stands as an exemplary headphone amplifier that showcases a succinct array of premium components. Drawing inspiration from the esteemed lineage of SPL's top-tier headphone amplifiers, this remarkable device is fortified with the groundbreaking Phonitor Matrix technology, which artfully emulates the immersive sensation of mixing on professional-grade studio monitors, ingeniously translated into the realm of headphones.

Delving into its meticulous design, the Phonitor One boasts a thoughtfully implemented set of features. Equipped with a centre-level preset permanently set at -1 dB, it ensures an optimal starting point for pristine audio reproduction. Additionally, the default speaker angle of 30 degrees mimics the widely favoured settings used by discerning sound engineers during mixing sessions.

The front panel of the Phonitor One houses a noteworthy function known as Crossfeed, a technical parameter known as "interaural level difference" that grants users the ability to determine the desired crosstalk between audio channels. This powerful tool enhances the perception of spaciousness and naturalness, amplifying the overall listening experience.

To ensure an unwaveringly consistent stereo image during extended listening sessions, the Phonitor One employs an ingenious power amp output stage. By thermally coupling each transistor, this ingenious design enables them to operate in perfect harmony, culminating in a reliable and faithful portrayal of sound.

The preamp stage of the Phonitor One is powered by two meticulously selected Burr-Brown OPA 2134 SoundPlus op amps, meticulously tailored for audiophile-grade circuits. These op amps exhibit an astonishingly low distortion value of a mere 0.00008%, further accentuating the amplifier's commitment to pristine audio reproduction.

Furthermore, the inclusion of a true FET stage within the preamp allows for an impressive slew rate of 20V/µs, endowing the device with exceptional responsiveness and vivacity during playback, elevating the overall dynamic range to new heights.

When it comes to the output stage, the Phonitor One showcases a specially engineered push-pull configuration operating in class AB mode. By harnessing the synergistic capabilities of bipolar transistors, this design amplifies both positive and negative half waves, resulting in amplified output voltage and gain, surpassing even the performance of traditional Class A operation.

In essence, the Phonitor One represents an immaculate fusion of meticulous engineering, cutting-edge technology, and an unwavering dedication to sonic excellence. This impeccable headphone amplifier stands as a testament to the pursuit of audio perfection, delivering a truly immersive and captivating auditory experience to discerning audiophiles around the world.
