Selling a very clean Acurus A100x3 power amplifier by Mondial.3-channel power amp – perfect for home theater or stereo setup100 watts per channel (8 ohms)High current design – drives most speakers easilyMade in USA – solid build qualityAll channels working perfectly, no issuesCondition:Very good cosmetic conditionFully tested, sounds clean and powerfulNotes:Power amp only (no volume control – requires preamp/receiver)Great upgrade for better sound and more power
At USD$461, this A100X3 sits well above your comparable median of USD$377—roughly 22% higher—putting it in ambitious territory for the used market. You're paying a premium here; typical used three-channel Acurus amps in this class trade closer to USD$350–USD$400, so this listing asks you to justify the uplift through condition, low hours, or included accessories. Unless this unit is documented as near-mint with original packaging and cables, it's a buyer's negotiation.
Before committing, confirm the amp's actual runtime and whether it's been recapped—these units are now pushing 20+ years old, and dried electrolytics are the silent killer. Verify the seller can demonstrate all three channels driving load cleanly (a quick 4-ohm test tone through each channel matters). Confirm what "Cables & Accessories" actually includes; if it's just basic RCA interconnects, that doesn't justify the premium. Get the serial number and cross-reference it with any service history.
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.
