A top-class headphone amp that can drive high or low impedance ‘phones to full power levels, with very low noise and distortion

Here’s a top-class headphone amplifier that can drive high or low-impedance phones to full power levels, with very low noise and distortion. For best performance, it can be teamed with the Stereo Preamplifier described last month. Alternatively, it can be used as a standalone unit, requiring only a power supply and a volume control potentiometer for use with any line-level signal source (CD/MP3 player). It even includes dual outputs, so you can listen with a friend!
