We are now building in our Connecticut factory a new type of amplifier with musicality that surpasses that of Class A and the energy-efficiency of newer Class G and H designs. Our iBias designs deliver all of this in a surprisingly compact package – and it also incorporates Internet-based technology that will amaze both audiophiles and systems integrators. The new line includes seven mode...[more]

This design gives the Krell amplifiers lower internal impedance, which allows firmer, more precise control of your speakers. Krell CAST Circuitry delivers the purest signal when connected to Krell CAST equipped preamplifiers. Power Supply Highlights One 750VA toroidal transformer feeds amplifier modules that include the audio circuitry, rectifier, and power supply filtering mounted to an indivi...[more]

A five channel power amplifier with output capability to drive any home theatre speaker system to realistic levels. The amplifier retained its stylish exterior with emphasis on build quality, efficient airflow and tempera- ture control.  A single chassis employs five independent amplifier modules, each with its own recti- fiers, filtering and regulation, etc.     By keeping the en...[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. Krell engineering considers this specification too lenient and not indicative of what an amplifier is required to p...[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]
