With the introduction of the Master Reference Amplifier in 1999, Dan D'Agostino established a level of amplifier performance without equal. The new X Series of Full Power Balanced monaural amplifiers are the direct descendants of this design. Sharing the same circuit topology as their stereo counterparts, the monaural amplifiers raise sound reproduction to a new level by dedicating an amplifier for each speaker. By effectively doubling the power supply available to each speaker, the Full Power Balanced.

Full Power Balanced X Series Monaural Amplifiers, continued...

Monaural Amplifiers deliver greater dynamic contrasts, vice-like bass control, and three-dimensional imaging. Available individually, in pairs, or in three, five, or seven unit Theater Packs, the Full Power Balanced X Series Monaural Amplifiers provide unparalleled sonic performance and flexibility to excel in any stereo, multi-channel audio, or home theater application.

The direct descendants of the awesome Master Reference Amplifier, the new Full Power Balanced X Series Amplifiers extend the Krell technologies of Sustained Plateau Bias and CAST. These advancements, now termed Sustained Plateau Bias III and CAST II, have increased the power output capability and bandwidth of the Full Power Balanced amplifier platform. All Krell Full Power Balanced X Series amplifiers also include the array of engineering advances that have made Krell the premier amplifier manufacturer in the world.

Class A output, the most linear and accurate topology for an audio power amplifier
Balanced topology for the lowest noise and greatest detail retrieval from a recording
Massive power supplies for complete dominance of a speaker
Fully regulated power supply and output stage operation for stability under all power line and speaker fluctuations
Virtually unlimited power output to drive loudspeakers to their peak levels of performance
In addition to these technologies, the new X Series increases the power to unprecedented levels, from the 300 Watt per channel Full Power Balanced 300cx Stereo Amplifier to the incredible 750 Watt per channel monaural amplifiers, the Full Power Balanced 750Mcx Monaural Amplifiers. The new X Series offers three stereo amplifiers and three monaural amplifiers, allowing the user to select the combination which best meets their stereo, multi-channel audio, or movie needs.
