About the GFA-5500
The Adcom GFA-5500 is a high-performance stereo power amplifier delivering 200 watts per channel into 8Ω. Featuring a 1.5 kVA toroidal transformer and ten MOSFET output devices per channel, it employs completely isolated secondary power systems to eliminate ground loops. The modular design places each channel's circuitry on a dedicated PCB mounted to outboard heatsinks, with thermal protection and distortion alert LEDs. Its Nelson Pass-inspired three-stage design delivers detailed sound with a damping factor of 700 and THD below 0.02%.
