The Harman Kardon HK 3490 is a $499 stereo receiver with 120 watts per channel and wideband amplification, which extends frequency response to 110kHz. Although the range of human hearing is limited from 20Hz to 20kHz, a wideband amplifier reproduces higher harmonics that contribute to better music reproduction in all frequencies. The HK 3490 is a good sounding receiver and I would recommend it for a moderately priced stereo system. Read my full reviewof the HK 3490.
