The Rogue Audio Cronus Magnum II is a 100 WPC all-tube integrated amplifier with an onboard MM phono stage and dedicated headphone amplifier, built around a massive high-storage linear power supply and heavy 2-oz copper circuit boards for high current delivery and dynamic headroom. It uses a tube complement of (2) 12AX7, (3) 12AU7, and (4) KT120 output tubes, feeding output transformers with 4 and 8-ohm taps and offering a bandwidth of roughly 20 Hz-30 kHz. The Cronus Magnum II provides four RCA inputs (one MM phono plus three line-level), gold-plated inputs and binding posts, buffered variable outputs for subwoofers or bi-amping, and a 1-2 W solid-state headphone section, making it a complete hub for vinyl, digital, and headphone listening in a single chassis. Widely praised for its lively, tonally rich yet controlled sound, it combines tube warmth with strong dynamics and grip, working well across a broad range of music.
