About the SE-300B

The Thöress SE-300B Monoblock Power Amplifier is a meticulously crafted, all-tube power amplifier from Germany, employing the legendary 300B directly heated triode in a single-ended, pure Class-A topology. Each monoblock delivers up to 10 watts into 4, 8, or 16 ohm loads, making it ideal for high-sensitivity loudspeakers. The design is minimalist, with zero global feedback and a powerful single-stage driver using two CV2382 (EL822) pentodes in triode mode. Output transformers are mechanically decoupled to minimize vibration, and output impedance is selectable at the factory. The amplifier is renowned for its natural, transparent, and dynamic sound, with exceptional frequency extension and virtually no transformer resonance. It is a reference choice for SET enthusiasts and audiophiles prioritizing musicality and purity of tone.
