About the 66 Magnum

The Rogue Audio 66 Magnum is a heavily upgraded version of the Rogue 66 line-stage tube preamplifier. It features a larger power supply, upgraded coupling and output capacitors, Dale-Vishay resistors, gold tube sockets, and high-quality NOS tubes, resulting in improved transparency, greater dynamics, and enhanced bass and high-frequency response. The preamplifier offers a warm yet detailed sound signature with quick, clean transients and natural timbres, especially in percussion. It has excellent bass extension that is nimble and articulate without sounding too tight. The Magnum 66 is built with a solid machined aluminum front panel and knobs, and includes a minimalist remote control with volume up/down buttons. It supports switchable Tape Out/second main out useful for bi-amping. The unit is praised for its balance, dimensionality, and smooth dynamic performance, making it a strong value proposition in tube preamplifiers. It typically comes with a pair of 12AU7 tubes, remote control, power cable, and manual. The The preamp is well regarded for its build quality and sonic performance in the audiophile community.
