About the SA/1
The Threshold SA/1 is a monoblock solid-state power amplifier from Threshold's SA-series of STASIS amplifiers, delivering a rated 160 watts into 8 ohms in Class A operation with very wide bandwidth and low distortion. Designed under Nelson Pass at Threshold, it employs the company's proprietary STASIS output stage and a highly linear voltage amplifier run in Class A, allowing the output transistors to supply high current to demanding loudspeaker loads while maintaining signal accuracy, and doing so without a global feedback loop. The SA/1 is built as a heavy, robust monaural chassis with large toroidal transformers and substantial output devices, and is known for its ability to drive low-impedance speakers with control and authority, while offering transparency, imaging precision, and a neutral tonal balance that has made it a sought-after vintage reference among audiophiles.
