Audiophiles everywhere, meet your next object of desire.

As the most powerful stereo-integrated amplifier ever to 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 it can handle the most demanding loudspeaker loads with the greatest of ease.

As a complement to 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 for room optimization, dual subwoofer outputs and a high-current, ultra-wide bandwidth design for clear sound and more precise imaging. And that’s only the beginning. In its quest to overachieve, the powerful HK 990 takes additional strides in the area of versatility, offering six analog stereo audio inputs and four digital inputs to ensure optimal compatibility with various signals.

Superlative two-channel music reproduction is one of the toughest challenges for any audio component. In this regard, the HK 990 offers you a superb blend of irresistible features destined to win the affections of the most discerning of audiophiles.

Overview TechSpecs Support
High-current, ultrawide bandwidth design for uncompromised realism.
The 150-watt HK 990 stereo integrated amplifier outputs a cleaner, louder and more powerful sound than most amplifiers from other companies. The reason is simple. By utilizing something called high-current capability (HCC), which provides the instantaneous current necessary to precisely drive and control nearly any loudspeaker system, the HK 990 can accommodate more headroom during dynamic program peaks, influencing tighter bass and a superb transient response - at any volume level. The benefit? Heightened realism for whatever music, movies and multimedia you might be listening to.

Optimize performance with Real-Time Linear Smoothing (RLS IV).
Designed to push the performance quotient even further beyond typical harman/kardon® standards, Real-Time Linear Smoothing (RLS IV) is a feature that minimizes interference in digital-to-analog signals with two high-grade stereo analog devices (AD) 1955 DACs. The result? Richly detailed sound and noise level that remains in a non-audible frequency range with very high jitter rejection. This way, you'll always experience sonic refinement and a natural open sound stage - two benefits that should appeal to the most demanding of audiophiles.

EzSet/EQ II takes control of your settings - automatically.
Sit back, relax and let the HK 990 set the room's mood automatically thanks to EzSet/EQ II's room-equalization and system-calibration technology. Simplify system setup with the touch of a button while ensuring the most optimal listening environment possible, in just minutes. EzSet/EQ II even sets speaker volume, speaker balance and timing as well for your system's 2.2-channel surround-sound speakers. By automatically adjusting sound to suit your specific room conditions - including directing sound toward listeners in the ideal, seated position - EzSet/EQ II consistently proves that it knows how to read the room.

Get in sync with an HRS link
As one of the features that make the HK 990 a top-of-the-line audio system, high-resolution synchronization link (HRS link) lets harman/kardon® CD players lock themselves to the external clock of the amplifier to ensure a jitter-free connection. Similar to having the CD playback inside the amplifier, the HRS link carries both the system and data clocks of the amplifier, and the data stream from the CD player. As a cutting-edge feature that's fairly standard in high-end professional audio equipment, the HK 990's HRS link is designed to appease even the most discerning audiophiles.

Minimize signal disruption wherever possible.
When you're listening to audio, you want to have as little signal disruption as possible. With the HK 990's XLR inputs, you get balanced connections designed to reject both external noise (from power wiring, etc.) as well as internal crosstalk from adjacent signal cables. In addition to discriminating against noise and crosstalk, your XLR inputs also allow 6 dB more signal level on the line - so ultimately you'll get a higher signal-to-noise performance than before. Bravo.
