The Krell Current Tunnel (KCT) CAST stereo preamplifier holds the distinction of being the finest sounding, most technologically advanced, and most system friendly stereo preamplifier ever designed by Krell. It derives its name from the way the signal is routed from its input to its output. The signal is brought into the KCT in the current domain from a CAST source such as the Krell KPS 28c Compact Disc Player. The signal stays in the current domain as it travels through the KCT, protected from extraneous noise and unwanted signal interference as if it were in a tunnel. Using CAST technology and power supply regulation that is a direct result of the development of the Master Reference Amplifier, the KCT is able to deliver a usable bandwidth that extends to 1.5 MHz. The result is seamless, transparent musical reproduction of even the most dynamically demanding sources. Ease of operation is also accounted for in equal measure with features that include dual-zone operation, with independent volume controls, Theater Throughput for integration into home theater systems, and RS-232 controls for whole house automation. The KCT is a stereo preamplifier that delivers the ultimate stereo performance today and the opportunity for continued growth into the future.
