KRELL FPB-700CX

Second-hand. In good conditions. Shows signs of wear. Without original packaging.

The Krell FPB 700cx is a state-of-the-art stereo power amplifier and the flagship model in the Full Power Balanced Class A series. It stands out not only for its exceptional sonic performance but also for its imposing and refined construction, which perfectly embodies Krell's uncompromising engineering philosophy.

Aesthetically, it departs from the more austere design of earlier models, featuring a sculpted and more sophisticated front panel—part of the design evolution that came with the introduction of CAST technology. While this current-mode signal transmission requires a compatible preamplifier to be used, the overall design appears more modern and elegant. The integrated power cable further emphasizes the amplifier’s substantial and permanent installation character, conceived for high-end listening environments.

Sonically, the 700cx delivers an astonishing level of silence and neutrality, with virtually no tonal coloration. Rather than hearing the amplifier itself, the listener experiences the pure essence of the signal, rendered with exceptional clarity, resolution, and depth. Compared to previous models in the same line, such as the FPB 200, the differences go far beyond extended low-frequency response or increased power—they redefine the entire listening experience. The soundstage expands, musical images detach from the speakers with lifelike precision, and the midrange offers a three-dimensional transparency that deeply engages the listener.

The Krell FPB 700cx is designed for demanding audiophiles and high-end reference systems. It is not just powerful or precise—it is capable of emotionally involving the listener by disappearing from the sonic equation and letting the music speak on its own. For those with reservations about the so-called “Krell Sound” of earlier models, this amplifier represents a significant evolution—almost a reinvention—that truly deserves to be heard without bias.
