Spotless P250 features a robust, minimalist design with a 2mm thick, hand-painted steel chassis. Its clean lines are accented by a single red power indicator and a tactile power knob.

Inside, a custom-designed 500VA UI transformer provides ample power, while carefully selected components, including ON Semiconductor MJ15024G/MJ15025G audio output transistors, Vishay resistors, and Philips, Suren, and Wima capacitors, ensure high-fidelity sound reproduction.

The amplifier utilizes a fully symmetrical discrete amplifier circuit layout, maximizing performance and minimizing distortion. The M6 and M8 mounting points allows for further vibration isolation using aftermarket feet.
