The Allnic M-2500 is a flagship monoblock power amplifier designed to provide exceptional flexibility through support for multiple output tube types, including PX25, 300B, and KT150 tubes. Combining classic valve amplification principles with Allnic’s proprietary transformer technologies, the M-2500 is engineered to deliver both the tonal refinement of direct-heated triodes and the power reserves of modern beam tetrode designs.
A standout feature of the design is its ability to operate with different tube configurations, allowing users to tailor amplifier performance to their listening preferences. The amplifier incorporates Allnic’s proprietary Full Engagement output transformer technology, oversized nickel/FeSi-core transformers, and comprehensive bias monitoring systems to maximise efficiency, stability, and signal integrity.
The M-2500 further features soft-start protection circuitry, user-friendly bias adjustment controls, and analogue tube current monitoring meters. These refinements contribute to reliable long-term operation while making tube maintenance and monitoring straightforward for enthusiasts and experienced users alike.
