But how much of this bandwidth was being reproduced through these
receivers?  A GE Superadio III in Wideband mode would of course generate a
much more favorable opinion of analog AM audio quality than the analog AM
tuner section of Kenwood's IBOC tuner, whose audio response drops off like
a cliff at 3 kHz.

The only fair way to make these tests would be to compare the best that
analog AM can deliver (C-Quam AM Stereo with full NRSC bandwidth) versus
the best that IBOC AM can deliver (36 kbps "Enhanced"-mode stereo HDC),
irrespective of receiver-based limitations.
