About the Cronus Magnum

The Rogue Audio Cronus Magnum is a high-end, all-tube integrated amplifier designed and hand-built in the USA. It delivers 100 watts per channel into 8 ohms using four KT120 output tubes, coupled with a triode preamplifier stage utilizing 12AX7 and 12AU7 tubes. The amplifier features a large, oversized linear power supply for excellent low-frequency response and dynamic headroom. It includes a built-in moving magnet (MM) phono preamplifier, four gold-plated RCA inputs (phono plus three line-level), gold-plated binding posts, and active outputs for subwoofer or bi-amping. The chassis is robust with a machined aluminum faceplate and optional tube cage cover. The Cronus Magnum offers a bandwidth of 20Hz to 30kHz, slow start turn-on sequencing, and transformer taps for 4 and 8 ohm speaker loads. It is praised for its smooth, liquid sound, wide dynamic range, and ability to drive a variety of speakers with authority and composure. The amplifier measures approximately 18" W x 17" D x 5.5" H and weighs about 25 kg. It comes with a detachable IEC power cord and is fully tested and burned-in before shipping. The design emphasizes short signal paths, low noise, and precision components for transparency and musical accuracy.
