Krell CAST®
Unrivaled Sound Experience
Reserved for the Solo 375 and Solo 575 is our Current Audio Signal Transmission (CAST) inputs and circuitry—a revolutionary method of connecting analog audio components for unparalleled sonic performance. In traditional audio systems, each component is a discrete entity with unique characteristics that act upon the musical signal independently. Each component is unaware of the other components in the system. The cables that connect the components also have their own electrical characteristics, which affect the sonic presentation of the entire system. Krell CAST™ unifies individual components and interconnects them into an electrically linked whole. The original signal remains unaltered from source to speaker. Still equipped with standard connections for use with other components, the full expression of Krell technology is realized when the system is connected using Krell CAST MMF interconnects. Krell CAST connected systems offer significant improvements in every performance area: speed, precision, dynamic range, depth and width of the sound stage, transient impact, and tonal balance. Both the Krell Solo 375 and Solo 575 Mono Amplifiers are engineered to provide an unparalleled sound experience. Whether you choose the 375 for its exceptional power or the 575 for its enhanced performance, these amplifiers will elevate your audio system to new heights.
