Acurus A-100x3 is a high-power, three-channel solid-state power amplifiermanufactured in the USA by Mondial (under the Acurus brandIn Black Anodized Aluminum Front Plate Excellent Condition!!!
At US$475, this sits a bit above the US$350 median and just below the US$495 75th percentile, so it reads as a fair-to-slightly-strong asking price rather than a bargain. It’s not cheap, but it’s also not out of line for a clean example of this 3-channel Acurus.
What makes it worth a look is the usual Acurus appeal: sturdy build, high-current drive, and a reputation for sounding punchy and controlled in home-theater or front-stage duty. If the condition is truly clean and it includes the power cord and original packing, that adds real value for a heavier older amp. I’d buy it comfortably if the presentation is honest and the cosmetic wear is light.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Acurus emerged in 1993 from Mondial Designs in the United States, positioned as a more accessible counterpart to the acclaimed Aragon brand. Created to deliver high-end performance through minimalist designs, premium specifications, and made-in-America manufacturing, it targeted the specialty AV market against pricier imports. In mid-2009, Indy Audio Labs—co-founded by audio engineer Rick Santiago and physicist Ted Moore—acquired Acurus, revitalizing its legacy after a period of dormancy under Klipsch ownership.
The brand specializes in power amplifiers, AV control processors, and immersive home cinema solutions, blending cutting-edge audio technologies with system setup and control features. Recent offerings like the compact M8X and M4X amplifiers underscore its focus on multi-channel power for media rooms, gaming, and high-performance theaters, all engineered with proprietary electronics, robust mechanics, and intuitive software.
Acurus holds a strong reputation for delivering high-end audio at competitive prices, earning trust among discerning buyers for its rock-solid durability, authentic sound reproduction, and five-year warranty. As a premium American marque under Indy Audio Labs in Indianapolis, it occupies a niche in custom installations, appealing to knowledgeable enthusiasts seeking reliable, USA-built excellence without boutique excess.
