Krell - 600

were $46k/pair, now $36k

The Evolution 600 amplifier sits in the middle of the Evolution Series. Powerful enough for almost any application, the Evolution 600 is the amplifier choice in many stereo and home theater systems worldwide. This power capability is coupled to a new green operating mode that reduces standby electrical draw to a mere 2 Watts. As with all Evolution amplifiers, the Evolution 600 development began with a question, 'What is the most difficult scenario this amplifier will face?' The answer is a 2 Ohm speaker load. When the final design is complete, and the amplifier is presented with a typical 8 Ohm speaker, it practically coasts. This amplifier simply sings with this stress-free load connected. Outputting a daunting 600 watts of power and coupled to Krell Evolution circuit technology, the Evolution 600 is a velvet hammer. The Evolution 600 is equipped 2 2,200 VA transformers and 108,000 mF. This power source is the backbone for the output of the Evolution 600. With this foundation, the Evolution 600 delivers 600 watts into 8 Ohms, 1,200 watts into 4 Ohms, and 2,400 watts into 2 Ohms. The FTC mandates that power ratings are quoted using a 1,000 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 with our final specifications stated for .1% distortion. Krell Active Cascode Topology offers several performance advantages. It breaks through bandwidth limitations of conventional designs and delivers very high current. The usable bandwidth of an Evolution 900 is 300 MHz; triple the bandwidth of a typical high performance amplifier. The result is near perfect performance in the audible range with no phase anomalies typical of lower bandwidth designs. Evolution amplifiers feature Krell CAST technology. CAST is a unique circuit and connection breakthrough that eliminates distortions inherent in voltage based amplification. A complete Evolution (source, preamplifier, and amplifier) system, connected with CAST interconnects reduces the number of voltage gain stages to the minimum, one. The resulting noise floor is approaching the theoretical limit of technology.
