Krell's Legacy of Innovation

Crafted for the Audiophile

Krell has a long-standing reputation for pushing the boundaries of audio technology, and the Chorus line of amplifiers is a testament to this legacy. Each amplifier is meticulously designed and constructed to deliver the highest level of performance, with an emphasis on sound quality, reliability, and durability.

Krell Chorus 7200 XD: Uncompromising Performance

High Power, High Fidelity

The Krell Chorus 7200 XD amplifier delivers a commanding 200 watts per channel into 8 ohms and 400 watts per channel into 4 ohms, ensuring ample power for even the most demanding speakers. With seven channels of amplification, the 7200 XD is perfect for large home theater systems, offering the ability to drive multiple speakers with ease while maintaining consistent performance across all channels.

Advanced XD Technology

At the heart of the Chorus 7200 XD is Krell’s eXtended Dynamic (XD) Technology, which significantly reduces the output impedance to enhance speaker control and lower distortion. This results in a cleaner, more detailed sound that reveals the subtleties of the audio with exceptional accuracy. The XD Technology ensures that the amplifier maintains full control over the speaker drivers, providing a listening experience that is both powerful and refined.

Efficient and Cool Operation

The Chorus 7200 XD is designed with efficiency in mind. Krell’s iBias™ Technology allows the amplifier to operate in Class A mode for most listening levels without generating excessive heat, combining the sonic benefits of Class A with the efficiency of Class AB. The amplifier’s cooling system ensures that it runs at optimal temperatures, even during extended listening sessions, providing reliable performance for years to come.
