At US$160, this Integra ADM 30.1 is a strong deal, landing just below the 25th percentile of US$161 for recent comparable USD listings, with a median asking price of US$162. In the current used market for this specific stereo power amplifier, that price represents genuine value rather than a lukewarm fair offer.
The ADM 30.1 is well-regarded for its robust dynamic power, delivering 115W per channel at 3Ω and a damping factor of 60, making it ideal for controlling demanding speakers with precision. Its ultra-low distortion of 0.08% and wide frequency response from 5Hz to 60kHz ensure clean, transparent amplification. For a fellow enthusiast, this listing offers a high-performance analog backbone at a bargain price, especially if the unit is in original-owner condition with no missing accessories.

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.
