Onkyo has unveiled an exciting glimpse into the future of high-end home cinema with the PR-RZ91, a next-generation flagship AV processor teased at CES 2026. As the Japanese audio icon celebrates its monumental 80th anniversary in 2026, this ambitious preamplifier signals Onkyo’s bold return to dedicated high-channel-count processing, targeting audiophiles, custom installers, and reference-level home theater enthusiasts.
A New Era for Onkyo Flagship Processing
The PR-RZ91 stands out as a dedicated AV preamplifier (processor) designed to anchor elite multi-channel systems. Early previews from the show floor reveal a striking, massive chassis with a modern industrial aesthetic—featuring a prominent color display and a premium build that draws inspiration from ultra-high-end brands like Trinnov and StormAudio.
While full official specifications are still forthcoming (with a complete reveal and commercial availability expected in 2027), insider details and booth demonstrations point to groundbreaking capabilities:
- 15-channel processing support, enabling expansive immersive audio setups such as 9.2.6 or beyond for Dolby Atmos, DTS:X, and next-gen formats.
- Built-in Dirac Live room correction as standard, with optional upgrade support for Dirac ART (Active Room Treatment)—a cutting-edge technology that delivers superior clarity, tighter bass, reduced room modes, and minimized echoes for reference-grade performance.
- THX Dominus certification, positioning the unit as one of the most authoritative home cinema processors available for the most demanding environments.
This processor is paired conceptually with matching power amplification options, including the PA-RZ11 (an 11-channel power amp delivering 150W per channel), allowing enthusiasts to build fully separates-based systems that outperform traditional all-in-one AV receivers.
Why the PR-RZ91 Matters for High-End Audio
In an era where immersive audio demands ever-more channels and sophisticated calibration, Onkyo’s PR-RZ91 represents a significant leap forward. The return of a dedicated high-end preamp addresses the needs of custom installation pros and serious hobbyists who prefer separating processing from amplification for ultimate flexibility and performance.
Combined with Onkyo’s ongoing commitment to features like high-resolution streaming, advanced HDMI connectivity, and seamless multi-zone capabilities seen in current RZ-series models (such as the acclaimed TX-RZ70), the PR-RZ91 promises to elevate home theater to new heights.
As one of the most anticipated announcements from CES 2026, this “study” model underscores Onkyo’s renewed focus on premium, future-proof AV solutions amid its 80-year legacy revival.
