Headphone Amplifier


Like the XP preamplifiers, the HPA-1 is the result of great attention to detail. 

Starting at the power cord, the AC line is first filtered for high frequency noise and then isolated by a special toroidal transformer shielded by mu-metal for lower magnetic noise and shielded for electrostatic noise by a separate Faraday shield, grounded to analog ground. This is followed by fast/soft recovery rectifiers, generous CRC passive filtering and sophisticated discrete DC regulators and then more passive RC filters.
