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 don't be mislead humans have only two ears and stereo is still a significant life form. It's actually an update of our market leading RX-4100/4103. rated at 100 watts, we've reduced distortion significantly. It has inputs to accommodate your sound gear. And the sound is phenomenal as you'd expect from a company that dates its own existence to before stereo's birth. RX-4105 has at least one unexpected grace: the ability to independently select up to two sets of loudspeakers via the supplied remote control.
