The FTC mandates that power ratings are quoted using a 1000 Hz sine wave into a fixed 8 Ohm resistor with final power specification stated at 1% distortion. Krell engineering considers this specification too lenient and not indicative of what an amplifier is required to provide. Krell designs to a much stricter standard. Our power tests use a 20-20,000Hz signal into 8, 4, and 2 Ohm loads. Our p...[more]

The latest manufacturing technologies are used throughout the design including surface mount circuit pathways. Surface mount circuitry increases the usable real estate on a circuit board and allows for a more sophisticated circuit in the same area. Surface mount circuitry shortens circuit path lengths, eliminates parasitic capacitance and improves bandwidth. PRODIGIOUS POWER COUPLED TO LOW ...[more]

The Evolution 400 amplifier is the lowest powered monaural amplifier in the Evolution Series. With a robust 400 watt output into 8 Ohms, this baby brother delivers plenty of punch. Potent enough for almost any application, the Evolution 400 shares the same sophisticated circuit topologies as its larger siblings but packs it into a smaller chassis. The Evolution 400 is perfec...[more]

With this foundation, the Evolution 400e delivers 400 watts into 8 Ohms, 800 watts into 4 Ohms, and 1,600 watts into 2 Ohms. The FTC mandates that power ratings are quoted using a 1000 Hz sine wave into a fixed 8 Ohm resistor with final power specification stated at 1% distortion.

The Evolution Series culminates more than two decades of cutting edge audio design and includes stereo and home theater components that embody 26 years of Krell design and manufacturing excellence. When envisioning Evolution, Krell had a solitary goal - to handcraft a range of components that, simply put, were the best sounding products ever built. The result is a synthesis of almost impossible co...[more]

In this application, the Evolution 402e gets mated with the Evolution 707 Reference Surround Preamplifier/Processor and an Evolution 403e Three Channel Amplifier for ultimate home theater performance. Power Supply The Evolution 402e is equipped with two 2,200 VA transformers and 188,000 ÄĚĚŞF of capacitance. This power source is the backbone for the output of t...[more]

The new Evolution amplifiers enjoy the hereditary advantage, from faceplate to binding posts, first born in the Evolution One amplifier. Realized in monaural, stereo, and three channel configurations, the Evolution amplifiers bring the engaging reproduction of music and movie soundtracks debuted in the flagship Evolution One to a potent new platform. With virtually unlimited power available, de...[more]

Power Supply The Evolution 403e is equipped with two 3,000 VA transformers and 188,000 µF. This power source is the backbone for the output of the Evolution 403e. With this foundation, the Evolution 403e delivers 400 watts into 8 Ohms and 800 watts into 4 Ohms with three channels driven simultaneously. The FTC mandates that power ratings are quoted using a 1,000 Hz sine wave into a fi...[more]

The Evolution 505 SACD/CD Player, in an inspired stroke, eliminates a cause of distortion that has plagued digital disc playback from its inception. By taking the nascent analog signal from the DACs and leaving it in its native language, current, the finest musical subtleties and textural shadings are preserved. The result is a perfect analog of the original recording. Evolution circuit topology ...[more]

All Evolution Series components are available in diamond-cut silver and a luxurious black finish. The Evolution 525 DVD/SACD/CD Player builds upon the features and functions of the Evolution 505 SACD/CD Player, adding a state-of-the-art video engine that features stunning 1080p performance and video processing controls. Unlike other solutions that provide 1080p outputs through down- and up...[more]
