HiFi AM is stretching the definition of HiFi! Designing and building
a good receiver is not a trivial task. When I was a kid in Jr High and
didn't know any better I used whatever was at hand or I could scrounge
and most projects usually worked, and even worked better when
certain parts were substituted by trial and error. But in reality none
compared to the war surplus receivers I converted.

Last year I sold an old (but never-used) Sony stereo AM radio (for seven
times
what I paid for it). Checking it out, I located a local stereo AM station.
Tuning was tricky -- you had to find _just_ the right spot. But had I not
known
it was AM, it might very well have thought it FM. The sound was _that_
good.
Certainly hi-fi in the subjective sense of low distortion and coloration.

FM has a major advantage over AM that can be summed up in one word --
limiting.
You can get perfectly flat response without having a perfectly flat IF
strip.
