This headphone amplifier can convert the hi-resolution audio signals from digital sources and make them compatible with you headphones. From PCM (PC connection maximum) files rated at 384kHz/32-bit from computers, up to 48kHz/14-bit from iPhones and similar devices and up to 192kHz/24-bit through an optical connection. It can also support DSD files, sampled at 2.8MHz and 5.6MHz. It can work with Windows and Apple computers, Apple multimedia devices, Sony Walkman devices and smart phones of all platforms.Compact Powerhouse
With impedance rating between 8ohms to 600ohms, the PHA3 amplifier can deliver a frequency range of 10 to 100,000 Hz with as less as 0.1% distortion. The balanced audio outputs provide separate dedicated connections for left/right channel of headphones. Both of these audio ports have independent amps and hence are able to deliver an astonishing level of audio detail and clarity.Construction
