The Krell KSL is a high-performance line control preamplifier introduced in 1990, designed for pairing with Krell power amplifiers like the KST-100. It features a simple structure with balance and high-precision level controls, 4 input systems including balanced XLR options, tape I/O, and two parallel outputs. An optional plug-in phono amplifier supports MM/MC cartridges with adjustable switching and impedance. Praised by Stereophile for near state-of-the-art performance as a line amplifier, offering powerful cable-driving ability, low noise via balanced interfacing, and sound quality comparable to higher-end models. No longer manufactured.
