Sony’s PHA-2 headphone amplifier was named Best of Innovations at the International CES Innovations 2014 Design and Engineering Awards event for its effectiveness and great listening experience when used with portable audio players or smartphones.

The PHA-2 headphone DAC/amplifier is part of Sony’s new line of High Resolution Audio products introduced in October 2013, along with the TA-A1ES integrated stereo amplifier. Both products offer superior sound reproduction and have been specifically designed to support the latest high-resolution music sources.

The new PHA-2 portable headphone amplifier is the first portable DAC/amplifier to be compatible with virtually every high-resolution digital file format, including up to 192 kHz/24-bit PCM and both DSD (2.8 MHz) and double DSD (5.6 MHz). It features a variety of advanced technologies, including refinements such as an Asynchronous Transport Mode using a dedicated signal generator to reduce timing errors for more accurate, jitter-free converter performance. It also incorporates a high-precision D/A converter, along with devices such as a custom headphone amplifier IC with high slew rate and ultra-low distortion operation; output capacitor-less (OCL) current feedback architecture; and a dual power supply operation for more stable and accurate reproduction.

All of these select components are enclosed in a durable aluminum chassis, fully protected from external interference. The PHA-2 headphone amplifier also has a variable gain headphone input that supports a wide range of impedances. It also has  Zinc die-cast bumpers to protect the volume control and headphone connector from external shock and vibration.

The PHA-2 can be easily connected to PC and Macintosh computers via its USB 2.0 interface, and also includes a dedicated digital input for iPod, iPhone and iPad products. Other portable audio sources such as Android smartphones and digital music players can be connected via the analog audio input. The PHA-2 comes with a built-in Lithium-ion battery, which runs up to 6.5 hours with a digital connection and up to 17 hours with an analog connection on a single charge.

The PHA-2 portable headphones amplifier will be available beginning March 2014 for $599 at Sony stores and other national electronics retailers.
