Threshold S/150 II

Description

Up for sale is a beautiful Threshold S/150 Series II stereo power amp featuring Nelson Pass’s legendary Stasis topology. This is for those who want something a little smaller than the S/300. I ran both in parallel within my home audio. It enhances any system. Also a conversional piece because people see it and it blows their mind. Original owner. Works as intended. Kept in custom cabinets so handled by very few. Comes with certificate of ownership. Blurred out in photo but very clean. If you are looking at this, you likely already know the pedigree. Unlike later designs that lean toward analytical or dry, the S/150 II strikes a perfect balance. It is incredibly musical, effortless, and sweet - often described as having a tube-like midrange warmth while retaining absolute solid-state authority, grip, and dead-silent backgrounds. It images beautifully and drives difficult speaker loads without breaking a sweat. Specs & Condition: Power: 90 watts per channel into 8 ohms (pure Class A/AB optical bias) Condition: Excellent cosmetic. Faceplate is clean, fins are straight, unmarked, and it performs as it should. The only item that shows some usage is the rubber power inlet but I'll include an extra if you should ever want to replace with exact OEM part. But it works as intended as is. Sound: Warm, coherent, punchy, and fatigue-free. It will make any system sound great. An absolute tank of an amplifier built during Threshold's golden era. I am a fast shipping but this one needs some attention so give me a couple of days to package. Not a store.
