The Adcom GFA-5800 two-channel power amplifier gives a power-packed
performance every time and with every application. The range of sounds
produced by the 400-watt amplifier reproduces audio with crisp clarity.
It maintains a constant output of power with a high damping factor. With
250-watts per channel, the delicate sounds of instrumentals and the
thumping bass of heavy metal are pumped out with outstanding audio
quality. The signal to noise ratio is 100 dB. The heavy amplifier
produces distortion-free sound with very little vibration. The
amplifier, designed by Nelson Pass, utilizes an FET signal path and
MOSFET output devices for a warmer sound, and capable of operating in
very low impedance.
