Now if the station (WABC) didn't push their compressors so hard, it might sound quite respectable! The factory fitted system in my IS250 gives a good result on AM, but the quality varies a lot between stations and bandwidth is reduced on weaker signals - it also has some kind of noise gating, probably DSP based, that's very effective. The issue is moot for me though at home, I live on Sydney's Northern Beaches, AM reception is not great here.

WABC in Wide reminded me of the Sansui TU-X1 running in Wide on a strong local station. The TU-X1 sound emerging from a blackness of low noise & distortion thanks to its FET RF front end and hi-tech demodulation. Also agree with Ian that it could benefit being run through an expander like a DBX-3BX (three-band Expander)(which could further create a noiseless background as well)(I also built a Peak-Unlimiter into my 3BX that could be engaged for further signal [de]processing.)
