Adcom GFA-5400 Stereo Power Amplifier - 125W / 200W Per Channel [Expired]

no longer for sale

The GFA-5400 comes from a a family of amplifiers designed to be giant killers.  Amplifiers capable of sound qualities of well known models 2 -3X their price.  The 5400 uses multiple high-current discrete output transistors, each capable of handling large amounts of power.  The 5400 actually produces considerably more dynamic power that the power measurement suggest.  All of this is possible since the power comes from a tightly regulated, high-current toroidal transformer.

This amp was just acquired locally.  We bench tested it and it sounds excellent.  


  • Precision matched MOSFETs used throughout the signal path.

  • Over 50,000 µF of power supply filter capacitance with low ESR for greater reserve capacity.

  • Low number of gain stages improves signal reproduction accuracy.

  • Custom toroidal power transformer provides better regulation and greater peak current capability.

  • High quality, gold plated binding posts.

  • Independent thermal overload and distortion LED's for each channel.
