Thanks RHF. I am looking for other users' experience. My unit comes
from Radio Labs, with the filter upgrade (their so-called, "Clearmod"
modification).
The difference when I switch from AM wide to narrow is almost always
inaudible and, for all practical purposes, does not make any
difference without detuning the radio
in slow mode. I wonder if owners of the stock radio experience the
same.
(The Radio Labs people think this is the way the radio is supposed to
work, which I found puzzling and surprising)

This may be more of a function of the AM station's transmitter. Try
tuning off by 1 KHz so you get some sideband splatter. Can you hear
cymbals and sibilance, or do you hear crackling and popping? If it's the
latter, the station isn't transmitting any highs. See if the bandwidth
selector makes a difference while off tuned a little.

I don't know how I am able to post w/t registering but here is my experience with the modified one: I saw no difference between wide and narrow settings, so I tuned in a SW station while two more stations were 5kHz on both sides of it. I then noticed a difference but it was minimal. A person with a little hearing problem or in a noisy environment will not hear any difference. I was surprised and I wonder of the RadioLabs mos have caused it.
