The Integra ADM 2.1 at US$160 sits just above the median of US$150 from recent comparable listings, placing it between the 25th percentile (US$140) and 75th percentile (US$155), so the asking price is fair for a used unit in unknown condition. While not a bargain, it reflects standard market value for this stereo power amplifier, which originally cost several hundred dollars new and remains a solid entry into audiophile-grade integration.
This amplifier is well-regarded for its clean, linear power delivery and reliable performance in small to mid-sized rooms, offering a no-nonsense sonic foundation that pairs well with a variety of speakers. At US$160, it’s a worthwhile buy if the unknown condition turns out to be clean and functional, especially since Integra units from this era are durable and often retain original specs without major degradation. If the seller confirms it powers on cleanly and includes the original remote or rack ears, the upside becomes even stronger.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Integra traces its roots to 1969, when Japanese audio pioneer Onkyo launched the brand to showcase its most prestigious electronics, emphasizing integration and fusion in high-performance systems. Evolving from a premium label under Onkyo, it became an independent division in 1999 or 2000, targeting custom installers with gear optimized for seamless home automation. Today, under the Premium Audio Company—recently acquired by Gentex—Integra maintains its Japanese heritage while expanding accessibility beyond specialist networks.
The brand specializes in premium AV receivers, processors, and home theater components, including multi-channel amplifiers like the DRX 5.4 with 120W power output per channel. Its lineup features CD, DVD, and Blu-ray players, all engineered for advanced integration via the proprietary Integra Serial Control Protocol (ISCP). Integra prioritizes expandability, multi-zone capabilities, and smart home compatibility over standalone speakers, turntables, DACs, headphones, or cables.
Positioned as a high-end choice for discerning custom integrators and home theater enthusiasts, Integra commands respect for its world-class build quality, innovative control features, and benchmark-setting performance. No longer confined to niche channels, it now appeals directly to knowledgeable buyers seeking robust, future-proof systems that rival the best in the industry.
