Harman/Kardon HK650 Amplifier

Externally, Harman/Kardon devices, and amplifiers in particular, are very conservative, but therefore recognizable. Visually, it seems that the HK650 has a minimum of organs, but in terms of functionality, it follows the best traditions of the era of undivided supremacy of stereo sound. And besides, it has a full set of line inputs (four), the ability to connect two cassette decks and a phono stage input for an MM pickup head. The latter is especially for vinyl fans as a bridge from the past: some of the tested models no longer have such inputs. The branded vertical rocker buttons have two functions: pressing the top edge turns on the input selector (indicated in green), and the bottom edge turns on the recording selector (indicated in red). The Source Direct button turns off only the timbres, leaving the volume and balance controls in operation. The preamplifier output and power amplifier inputs are physically present on the rear panel and are connected by jumpers, which makes it possible to turn on an external processor when creating a complex with increased control flexibility.

The soft voice of Harman/Kardon seems to be covered with a slight morning haze, which, without reducing the contrast and accuracy of localization, slightly veiled the general background. But sometimes sharp outlines peep through the smooth contours, slightly sharpening the high frequencies. The low ones seem a little rolling, as if they are already being held back at the limit, and although sometimes there is a feeling of their "lowering", but the penetrating ability to penetrate into the depths of your soul turns out to be somewhat increased. In general, the sound of the amplifier is similar to a dance arrangement of martial arts. The original performance of a master of wu-shu or karate is characterized by sharp attacks and blows, fast movements (as sometimes they resemble an oscillogram of a rapidly changing musical signal). And in the dance, the movements seem to be the same, but they are performed with greater grace and, although they have somewhat lost their combat mission, they have acquired plasticity and a virtuous beginning. As if an invisible, thinnest net entangled the fighter, and his lightning strikes, slightly softened, acquired a theatrical fullness.
