The PM6005 integrated amplifier features an improved power supply that provides superior speaker driving capability, and is compatible with lower impedance speakers. In addition to analog audio inputs, the PM6005 also features optical and coaxial digital audio inputs for direct connection to digital audio sources such as a CD player and a digital television, for example. Featuring all discrete audio ciruitry, the PM6005 is also equipped with our HDAM discrete circuit modules, and the power amplifier features current feedback for wide range, low distortion sound quality with a wide range of speaker types. The power supply features large capacity Shottky Barrier Diodes that provide high current and high speed conversion capability. There are two sets of gold plated speaker terminals for connection to two pairs of loudspeakers, and the headphone amplifier is all discrete and is compatible with virtually any headphone type, regardless of impedance or sensitivity.
