At US$105, this sits well below the recent used median of US$220 and even under the 25th percentile at US$160, so it reads as a strong buy rather than a maybe. For a tested, working OEM power-supply part from a respectable Integra/Onkyo multizone platform, that’s the kind of pricing that usually makes sense to move quickly.
The appeal here is straightforward: these original transformer assemblies matter when you want a proper repair or a like-for-like restoration, and tested working status removes a lot of the usual guesswork. If your unit needs a replacement transformer, this is exactly the kind of parts listing that can save an otherwise good amp; just confirm compatibility and mounting details before committing, since the value is strongest when it drops right into your specific chassis.
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.
