Key Features
High-Resolution Audio for uncompromised sound
Experience digital music to the fullest with High-Resolution Audio. By capturing music at a higher rate than CD, increasing both audio samples per second and the bit-rate accuracy of each sample, High-Resolution Audio offers an uncompromised rendition of an artists' music. Savour every breath and subtle movement for a truly emotional experience.
Superior sound with a dedicated USB DAC amp
With a dedicated USB DAC amp connecting your headphones and compatible PC, smartphone or Walkman, you'll enjoy higher quality streaming of High-Resolution Audio. The amp takes over responsibility from your portable device for processing and converting digital data, then amplifies sound using its own integrated amplifier.
PCM support for pure quality
Get close to the original source. Supporting data volume that's about 6.5-times that of CD (44.1kHz/16bit), PCM (Pulse Code Modulation) handles up to 192kHz/24bit for a sampling rate and bit depth capable of reproducing wave characteristics that are very close to the original analogue wave. In addition to providing clear reproduction of high frequencies, PCM also enables subtle nuances and resonance to be expressed with high fidelity.
Wide frequency response for ultra clear harmonics
The wideband frequency range - spanning 10Hz to 100kHz - is designed for today's broad variety of music styles. At the 100kHz high-end, you'll be able to enjoy vocal melodies, subtle audio harmonics and tonality in outstanding clarity, as well as feel sound beyond your natural hearing. This is especially relevant with High-Resolution Audio, which unlike CD and MP3 music, supports high frequencies up to 100kHz for a more realistic, emotive sound.
High quality dedicated digital-to-analogue converter (DAC)
Digital-to-analogue conversion is required by any audio device to convert digital data (such as music files) into an analogue signal (to drive headphones or speakers). However, all DACs are not the same. Many portable devices incorporate DACs based on whether they fit within space and other limitations, but the PHA-1A is a dedicated device consisting of a high-performance DAC and amplifiers with the sole purpose of handling audio. That's why listening through the PHA-1A provides an audio experience that far surpasses listening through the built-in DAC of a smartphone, iPhone/iPod, or PC.
High quality components for pure sound
The digital source is converted to a pure, high quality audible with a 192kHz/24 bit capable DAC (WM8790), low-distortion low-noise operation amplifier (LME49860), high-power output high-fidelity headphone amplifier (TPA6120), and OCL amplifier output stage using two power supply methods.
Portable, lightweight design with durableness
Small and light at about 150 grams the PHA-1A has a rugged aluminium case to protect it from everyday knocks and shocks. Rounded edges make it easy to hold when out and about. Comes with a silicone band for comfortable carrying along with your Walkman, Xperia or iPhone.
