Notable mainly as a discontinued RBH rack/plate amp with DSP, and that gives it real niche appeal. At US$275, it lands above the recent market median of US$173 and also above the 75th percentile of US$219, so this is an ambitious asking price rather than a bargain.
The upside is that RBH gear is generally well regarded for clean, flexible bass integration, and this model’s DSP plus 250-watt output makes it a useful piece if you’re matching or restoring a compatible sub. “Tested” is good, but at this price I’d want confidence on the controls, input/output behavior, and whether any setup accessories or the original manual are included; otherwise, it’s a buy only if you specifically need this amplifier and want it ready to drop in.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
RBH Sound is an American loudspeaker brand founded in 1976 by Roger B. Hassing, beginning in Los Angeles before later relocating to Utah. It started as an OEM supplier, building speakers and providing engineering support for other names in the audio industry, and eventually developed its own brand identity. That long backstory gives RBH unusual depth for a relatively low-profile hi-fi company.
Today RBH is best known for speakers and subwoofers, including freestanding hi-fi models, custom-install/in-wall solutions, and products for home theater and commercial audio. The company has also offered active and personal audio products, but loudspeakers remain its core strength. Its engineering emphasis has historically included metal cone drivers and integration-friendly designs aimed at serious listening as well as discreet installation.
In the market, RBH sits as a niche American specialist rather than a mass-market brand. Its reputation is strongest among enthusiasts who value performance, build quality, and value over name recognition, especially in custom integration and home theater circles. It is not a vintage-collector brand, and it is not usually positioned as ultra-luxury; instead, RBH occupies a credible high-performance middle ground with a long, quietly respected heritage.
