Rotel RA-980BX. I own one since 1992 and except for some capacitors that needed to be changed 10 years ago, it has performed flawlessly. Clean and simple design, quality built, plenty of power. They do not come up very often in the US but if they do they usually go for less than $500. Here is some info on it: https://www.hifiengine.com/manual_library/rotel/ra-980bx.shtml
