About the M250
The Rogue Audio M-250 Ultra monoblock amplifier represents the pinnacle of Rogue Audio's tube amplification technology, succeeding the Apollo Dark Monoblocks. Unveiled at AXPONA 2026, it provides 250 watts per channel in ultralinear mode using KT-88 output tubes, with the ability to switch on-the-fly to triode mode for a more refined sound. Designed without compromise, it boasts a perfectly flat frequency response, enormous bandwidth, gigantic dynamic range, and negligibly low distortion thanks to massive linear power supplies, ultra-high tolerance components, and huge transformers. The monoblock design ensures perfect channel separation. Features include built-in bias meters with individual bias switches for easy tube setup, balanced (XLR) and single-ended (RCA) inputs with heavy-duty rhodium-plated connectors, and Cardas or rhodium-plated binding posts for 4 and 8 Ohm speakers. CNC-machined aluminum front and side panels contribute to its premium build quality. Fully tested, burned-in, and auditioned, it is entirely designed and built in the USA.
