Bellari is a division of Rolls Corporation, based in Salt Lake City, Utah, that designs and hand-builds tube-based audio equipment in the United States. The brand was established in 1989 as Rolls' higher-end line, focused on bringing the warm, musical character of vacuum-tube circuitry to affordable rack and desktop gear for home studios, project studios, and hi-fi enthusiasts.

Bellari is best known for its tube phono preamps — the VP130 and VP530 in particular have a long-running reputation in the vinyl community — along with tube microphone preamps like the RP220 (dual channel) and the RP533 studio multi-processor that combines a tube mic pre with a compressor/limiter, sonic exciter, and VU metering in a single channel. The broader catalog includes headphone amplifiers (HA540, HA543), tube buffers (BA525), sonic exciters (SE560), power and integrated amplifiers, equalizers, and accessories such as moving-coil step-up transformers and Bluetooth receivers.

The brand occupies a practical niche: tube tone and hand-built, US-made construction at price points well below boutique studio gear. Bellari pieces show up frequently on the used market and in discussions on forums like Gearspace and Audiogon, where the VP130 phono stage and the RP-series tube preamps are commonly recommended as entry points into tube-flavored signal processing.

Bellari has 10 products cataloged on Equipboard, including Preamps, Effects Processors, and Headphones & In-Ear Monitors. Their gear is featured by 2 artists, with the strongest followings in Rock, Electronic, and Hip Hop. Notable users include DJ Harrison and Kevin Parker.
