Breathe new life into your music collection with the PHA-2A headphone amplifier. Just plug in your amp and discover the difference of balanced sound and High-Resolution Audio. Sit back, relax and enjoy music that’s closer to the original recording.
Direct Stream Digital
Hear the authentic, intimate detail of analog sound from your digital audio with Double DSD (5.6 MHz) and DSD (2.8 MHz) high-quality digital audio coding.
The newly developed Φ4.4mm balanced connection cable separates left and right sound signals, while minimising signal transmission loss and resulting sound deterioration.
Pulse Code Modulation
Enjoy the best possible sound quality through a range of Sony devices and smartphones with up to 192 kHz / 32-bit PCM encoding.
Discover balanced audio
A balanced connection separates audio channels, eliminating interference. This ensures a distinct tone and enhanced dynamic range within an expansive acoustic field.
The way the artists truly intended
Enjoy the subtlest nuances of studio-quality sound in higher than CD quality with High-Resolution Audio. Passion for music unites every component from signal to speaker so it feels like the artist is performing right in front of you.
Pure sound meets precision engineering
Discover how developments in design make the PHA-2A easier to control, more intuitive to handle and a pleasure to listen to.
Clock generators set the sample rate timing for digital-to-analog conversion. Designed to work at multiple frequencies, the precise clock ensures audio is accurately reproduced, creating the stable sound the composer intended.
A high quality volume dial regulates how voltage is delivered to the headphones. Low resistance ensures there is little signal lost, allowing you to precisely control the volume, for comfortable listening.
A gain switch lets you adjust the input signal from the source, which in turn, affects the range of volume control. Depending on how sensitive your headphones are, the balance of gain and volume comes down to personal taste.
Small, light and durable
With the lightweight chassis and silicone band, you can easily carry the amp with you. Its rugged aluminium case protects it from everyday knocks and shocks.
