The Threshold SA/1 is arguably the amplifier that canonized Nelson Pass' place in hifi history. With unparalleled transparency, detail, and depth of image, the SA/1 is an outstanding monoblock. This spectacular pair comes from a single-owner system, and has been fully serviced. They're well balanced, and each deliver a clean 180 watts – 20 watts better than manufacturer spec. They will ship in their original boxes, and the manuals are included. Simply stunning.

LINER NOTES
Combining extraordinary sweetness with remarkable detail, depth, breadth, focus, and low-end impact and control, this is now, hands-down, the best-sounding power amplifier I have used. It's become my preferred amplifier for driving the Martin Logan Monolith speakers, as well as just about every other speaker.
