About the Apollo

The Rogue Audio Apollo monoblock power amplifiers are high-power, all-tube designs delivering 250 watts per channel, created as the company's flagship reference amplifiers for demanding loudspeakers and critical listening systems. Built in the USA, each monoblock uses a fully dual-mono architecture with massive linear power supplies, high-performance output transformers, and a robust, CNC-machined aluminum chassis. User-selectable triode and ultralinear modes, front-panel standby and power controls, and rear-panel 4 and 8 ohm binding posts provide flexibility with a wide range of speakers. Connectivity includes balanced XLR and single-ended RCA inputs. Integral bias metering and an included bias tool allow straightforward output-tube bias adjustment and maintenance. The Apollos offer wide bandwidth from 10 Hz to 100 kHz, 250 W output with less than 0.1% THD, and are designed to combine high power, fine detail retrieval, and smooth tube tonality in a reference-grade monoblock package.
