T200

About the T200

The Threshold T-200 is a Class A solid-state stereo power amplifier designed by Nelson Pass, known for its balanced tonal neutrality, precise imaging, and lively dynamics. It delivers 100 watts per channel into 8 ohms, 200 watts into 4 ohms, and can be bridged for mono operation to provide 350 watts into 8 ohms. The amplifier features a five-stage design with a triple series/triple parallel/triple Darlington output stage and dynamic bias circuit, embodying the STASIS topology which ensures constant voltage and current linear operation without overall negative feedback. It has switch-selectable balanced XLR and unbalanced RCA inputs, and a safety-locked switch for stereo or mono operation. The T-200 is noted for its high build quality with a sculpted brushed aluminum faceplate and robust construction. It runs warm due to its Class A design and requires adequate ventilation. The amplifier is praised for its coherent and balanced sound presentation, offering tonal neutrality and transparency across the frequency range. It was originally
