Condition unknown, but at US$99 this is a solid ask for an AmPlus 100. Recent used examples cluster roughly around US$75 to US$150, with clean working units and refurbs often landing closer to the middle, so this sits in fair-to-good-value territory rather than bargain-bin or ambitious pricing.
What makes it worthwhile is that this is a genuinely capable, no-nonsense Bose business amp: quiet, compact, and reliable for small stereo systems or 70V/100V duty, with enough power for background or modest hi-fi use. If the listing includes the correct power supply, intact connectors, and it powers up cleanly with no hum or channel dropouts, it’s a sensible buy at this price.

Bose Corporation traces its roots to 1964, when MIT professor Amar Gopal Bose founded the company in Natick, Massachusetts, after growing disillusioned with the poor performance of a high-end stereo system he purchased as a graduate student. Driven by a passion for replicating the immersive qualities of live music through rigorous acoustic research, Bose launched the venture with initial contracts for the U.S. military and NASA, emphasizing innovative speaker designs that prioritized indirect, reverberant sound over direct radiation. This American heritage, rooted in psychoacoustics and engineering excellence, has defined the brand's pursuit of "Better Sound Through Research."
Bose excels in consumer and professional audio categories, renowned for its home audio systems, premium speakers like the iconic 901 Series, and pioneering noise-canceling headphones first prototyped in the 1980s for pilots. The lineup extends to vehicle sound systems, portable Bluetooth speakers, and professional installations, but steers clear of niche hi-fi components such as amplifiers, turntables, DACs, or cables, focusing instead on integrated, user-friendly solutions that blend advanced signal processing with spatial audio reproduction.
Positioned as a premium mid-tier powerhouse in the global market, Bose commands widespread appeal among discerning buyers seeking accessible high-performance audio without audiophile esoterica. Its reputation for innovation and reliability has built a loyal following, though purists occasionally critique its measured sound signature, cementing Bose as a dominant force in mainstream hi-fi rather than high-end boutique or vintage realms.
