In our modern, surround sound driven audio universe where home theater enthusiasts hear airplanes fly overhead and bombs exploding around them, one might think that mere Stereo is old fashioned. But dont be mislead humans have only two ears and stereo is still a significant life form. Our case in point: the new RX-4105. Its actually an update of our market leading RX-4100/4103. rated at 100 watts, weve reduced distortion significantly. Its now less than 0.20% from 20 Hz to 20 kHz and weve improved the reliability with a new layout borrowed from our higher end models. The RX-4105 has a good AM/FM tuner with the ability to pre-set up to 30 favorite stations. It has inputs for 4 audio sources to accommodate your sound gear. And the sound is phenomenal as youd expect from a company that dates its own existence to before stereos birth.
