I was asked by a friend to repair his sx1980. After repairing the power supply and output protection circuit, I fired this monster up. Holy cow! What a beast. This is the holy grail of stereo receivers. The amazing tight and crisp lows and the bright and sparkling highs absolutely blew me away. I played this receiver through my Event EV20/20 monitors. This receiver changed my life. I remember lusting after these silver face beauties when I was at Georgia Tech back in the day. Of course I couldn't afford one back then. I've bought two Pioneers (sx850 and sx780) since working on this beauty and am once again in love with them. If you want the holy grail of stereos, then save your bucks and find one of these monsters.
