DESCRIPTION :

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. While the 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.
