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.
