Packed with the latest technological advances, for extraordinary musicality.

The K-300i incorporates a newly developed amplifier circuit design with Krell iBias™ technology,  delivering 150 Watts/Channel into 8Ω and 300 Watts/Channel into 4Ω. iBias provides the sonic benefits of Class A operation without the excessive heat and power consumption of traditional Class A design.

Packed with Krell’s latest technological advances, the K-300i achieves an extraordinary level of musicality. It’s elegant design is living room-friendly, while delivering more than enough power to achieve incredibly lifelike dynamics with any speaker.

The overall result is an extremely linear and extended frequency response curve with smooth, effortless highs and extremely dynamic bass energy.

DIGITAL OPTION

With the digital option installed the K-300i becomes a world class DAC with the connectivity and features to support the latest digital music formats. An ESS Sabre Pro DAC configured for high current output performs the digital to analog signal conversion for uncompromised reproduction of digital music.

POTENT POWER SUPPLY

771VA transformer with 80,000μF of capacitance forms a potent power supply for excellent signal control and dynamics. Krell Current Mode topology is employed with fully differential circuitry that runs from the input stage through to the last output gain stage providing an extremely linear and extended frequency response curve with smooth, effortless highs and extremely dynamic bass energy.

THEATRE THROUGHOUT MODE

The front-panel menu system provides configuration features such as input trim. Theatre Throughput mode lets the K-300i serve as the core of a surround-sound system without sacrificing two-channel sound quality. Analog Inputs include three stereo RCA and two stereo balanced XLR. High-quality gold-plated speaker cable terminals provide a secure, electrically ideal connection.

CUSTOM INSTALLATION FEATURES

The K-300i also offers features that make it perfect for custom installation, such as RS-232 and Ethernet ports for control and status feedback, 3.5mm jacks for IR input, and 12-volt trigger input and output. Additionally, the unit has an internal web server that is optimised for tablets and provides a remote graphical user interface for convenient and intuitive control accessed through its Ethernet connection.

NETWORK STREAMING

A network streaming audio renderer with dedicated mobile App plays AAC, ALAC, AIFF, FLAC, WAV, WMA, and DoP files up to 192kHz/24-bit from UPnP music servers or NAS devices. The digital option with the mconnect Control app (available in iOS and Android versions) also provides Spotify*, vTuner Internet radio, Tidal*, Deezer*, and QoBuz* streaming services, is Roon Ready* and decodes MQA.

MQA

The K-300i includes MQA (Master Quality Authenticated) technology. MQA is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. 

HDMI 

HDMI 2.0 inputs and output supporting 4K UHD with HDR are available for TV viewing with audiophile grade sound quality. A single USB host port is available on the front panel to play music from USB flash memory sticks and a USB device port is positioned on the rear panel for streaming music directly from a computer. The digital option also includes a Bluetooth receiver featuring Qualcomm® aptX™ audio technology for the best sound quality when connected to aptX enabled Bluetooth devices.
