I know as a kid in the seventies, my other young audiophile friends thought it was weird when I had an AM antenna hooked up to my various receivers. I agree with the thread here that most are too broad for serious DXing, but a couple were very nice sounding with a strong signal, and there were a few NYC stations that I would listen to as well as the local Kingston station WKNY.
The Sonys I had were usually bad, as were the Kenwoods, but my older Pioneer SX receivers always had nice AM. Later on I had a Yamaha component tuner that was very impressive, but locked to 10 Khz tuning. The best performing AM-capable receiver I ever owned though was an old Fisher tube receiver. I wish I still had that one.
I think what I always wanted in the "stack" with the rest of the components was a McKay-Dymek DR-33. Maybe someday I'll splurge on a clean used one. They still command a pretty hefty price.
