Don’t forget about harmonics

Music are complex electronic waves that more likely have higher harmonics that go beyond 15 kHz or even 20 kHz, and FM limited bandwidth tend to filter out higher harmonics. That is why for high quality medium such as SACD, the noise filter (signal bandwidth) is set at 44 kHz instead of 22 kHz which is for CDs.

Limited bandwidth (15 khz) also mean limited Dynamic Range and S/N ratio.

Are you using a HD tuner (Sangean??) hooked up to your system or a tabletop radio?
