For sale a stereo Adcom GFA power amp, with RCA and balance input, claimed as a Nelson Pass Design.  
 
Very heavy weighting 62 lb and robust built. it is priced to go fast at HK$2800.  
 
History: One of my family members bought this from HK dealer to drive a sub-woofer system over 10 years ago but project suspended due to other engagement. No box, no invoice due to house moved.  
 
Feature: 250-watt rating per channel, with input option either XLR or RCA  
Working condition: 100%  
Cosmetic condition: 90%, some rust found at speaker plug due to rare use  
 
Specfication abstracted from internet source:  
The GFA-5800 is unlike most amplifiers as it uses only MOSFET's in the signal path. NO bipolar transistors anywhere.  
It also simplifies the signal path by using only three gain stages.  
Built-in Bi-wire capability  
250 + 250 watts RMS into 8-ohms from 20-20,000-Hz @ 0.18% THD  
400 + 400 watts RMS into 4-ohms from 20-20,000-Hz @ 0.18% THD

Dynamic Headroom @ 4-ohms: 2.1dB  
IM Distortion: (CCIF 4kHz-20kHz) 100dB  
Damping Factor from 20-20,000Hz: > 1100 (incredible!)  
Gain: Unbalanced (29dB), Balanced (26dB)  
Dimensions: 17" W x 8" H x 13.5" D  
Weight 62 lbs  
 
Due to the exceptional 62 lb weight, self-pick at Hung Hom and no delivery service.
