Harman Kardon HK 3700

The HK 3700 is a stereo receiver from Harman Kardon, designed to serve as the central component of a personal audio system. It brings together amplification, an AM/FM tuner and both analogue and digital connection capabilities in a single unit, allowing a classic hi-fi setup to coexist with modern sources.

The amplification delivers a power output of 170 watts, enough to drive a pair of speakers in typical domestic use. The HK 3700 incorporates a 192 kHz / 24-bit digital-to-analogue converter, allowing it to process digital audio streams at high resolution before outputting them through its analogue outputs. On the connectivity side, the unit connects to the home network via Ethernet and supports DLNA 1.5, allowing playback of audio content stored on other devices on the local network. A USB port also allows connection of a storage device or an Apple device running iOS. The dedicated phono input, meanwhile, allows a turntable to be connected without an external preamplifier.

This type of receiver is aimed at a user wishing to centralise their sources around a single unit rather than multiplying separate boxes: turntable, radio tuner, content stored on the home network and Apple devices all share a common connection point here. It suits a medium-sized living room setup where the aim is to combine traditional analogue listening with current digital uses, without resorting to a more complex multi-component system.
