I've found that AM radio can sound remarkably good with the older tubed tuners. I have a Fisher Model Eighty AM/FM tuner/preamp in my workshop system connected to a homebrew SET 6B4 amplifier driving a single Klipsch Heresy speaker. There is not much music on AM anymore but it makes ballgames more fun to listen to. FM sounds good as well through this system.
AM radio was the primary music medium for the first half of the twentieth century. Effort was made to make AM radio sound as good as possible. Audiophile revered tubes such as the 76, 45, and 2A3 were developed for console AM radios, the "hi-fis" of their time.
