As the most powerful stereo integrated amplifier to ever carry the Harman Kardon® name, the HK 990 captures listeners’ attention – and how could it not with its expectation-defying 150 watts of power per channel. And even though the HK 990 may amaze some with its musical prowess, make no mistake, its power is highly refined – and can handle the most demanding loudspeaker loads with the greatest of ease. To complement this muscularity, the HK 990 also boasts an impressive list of advanced performance features, such as fourth-generation Real-Time Linear Smoothing (RLS IV), EzSet/EQ II for room optimization, dual subwoofer outputs and a high-current, ultrawide bandwidth design for clear sound and more precise imaging. And that’s only the beginning. In its quest to overachieve, the powerful HK 990 also takes strides in the area of versatility – offering six analog stereo audio inputs and four digital inputs to ensure optimal compatibility with various signals. Ultimately, the HK 990 offers you a superb blend of irresistible features designed to win over the affections of the most discerning of audiophiles.

When you invest in a new amplifier, you want a system that stays compatible for years to come – no matter what technological advances come along. To grant you this flexibility, the HK 990 features connections for six analog audio devices and two analog recording devices. And with a total of four digital inputs and one coaxial digital output, which allow the stereo amplifier to handle all the latest digital audio sources, there’s one thing the HK 990 won’t be short on: longevity.
