When you want your music to sound its best, you just can’t beat a good two-channel stereo. Connect your speakers to the Harman Kardon HK 3770 and this powerful receiver will bring those tunes to life the way they were meant to be heard. Whether you’re listening to songs from a CD, turntable, networked computer, or a smartphone, this receiver has the connectivity to play them and the brawn to bring out their dynamics and detail. Digital inputs even allow it to improve the sound of TVs and streaming media players like Apple TV®, too. With so much versatility, this receiver goes above and beyond old-school models, while retaining classic Harman Kardon sound.

Harman Kardon has been working to make their receivers more energy efficient without compromising sound quality. The HK 3770 represents the fruits of their labor. It utilizes Harman Kardon’s GreenEdge™ technology. Rather than redesigning the high-current Class AB amplification stage, this receiver features a new digital power supply. Unlike conventional analog power supplies, this new digital design uses less energy, fewer raw materials, and produces less heat. The result is a lightweight, efficient, eco-friendly receiver that delivers the same sonic benefits we’ve come to expect from this audio innovator.
