The Full Power Balanced X Series
Stereo Amplifiers offer the greatest
performance possible from a stereo
amplifier. All X Series amplifiers
share the same circuit topology,
from the 300 Watt Full Power
Balanced 300cx and the mid-level
FPB 400cx at 400 Watts, to the
awesome 700 Watt FPB 700cx, the
most powerful stereo amplifier ever
offered by Krell.

FEATURES

While the Full Power Balanced X Series Stereo amplifiers have
much in common, there are also some important reasons for
investing in the additional power. Each amplifier houses a
massive power supply, doubling in size with each step. When the
power increases from 300 Watts to 400 Watts and 700 Watts, the
power supplies increase from 2000 Watts to 4000 Watts to 8000
Watts, respectively. While intuitively one might think that the
only benefit of additional power from the same electrical design
is the ability to play louder, the huge power supplies in the X
Series provide empirical evidence that says the amplifiers do
much more. More power delivers more authority on the low end,
greater ease through the critical midrange frequencies, and
effortless highs. In short, with every significant increase in
power, there is a palpable increase in the believability of the
sonic presentation.

The direct descendants of the awesome Master Reference
Amplifier, the 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.

A 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 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 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.
