Remote Controlled Stereo Receiver. Our case in point: the new RX-4105. It's actually an update of our market leading RX-4100/4103. rated at 100 watts, we've reduced distortion significantly. It's now less than 0.20% from 20 Hz to 20 kHz and we've 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 you'd expect from a company that dates its own existence to before stereo's birth. And the RX-4105 has at least one unexpected grace: the ability to independently select up to two sets of loudspeakers via the supplied remote control. (Audio purists will be pleased to know that this relay-controlled switching puts the speakers in parallel, maintaining their individual sound qualities.)
