What to look for when buying Stereo power amplifiers - 1959 Hi-Fi Review

Hi-Fi review examines 5 really nice amplifiers of the day. I have the Knight so their comments about it are really interesting to me. I'm rebuilding it this year to use on the bass section of my next horn system. It should be fine for that duty. If I could pick one out of this list it would be the Leak. Always wanted one.
