The HQ2002S was a serious, lightweight high-power amplifier in Tsunami’s lineup, and at USD 500 this is a strong deal by the numbers: your 31-listing sample has a USD 110 median and a USD 50 25th percentile, putting this above the median but still well below the USD 1,155 upper quartile. It is not a bargain-basement price, but it looks very fair for a properly working example.
Its appeal is substantial output in a relatively light rack chassis, with stereo or bridged-mono operation, balanced/unbalanced inputs, Speakon and binding-post outputs, protection circuitry, and controlled cooling. Contemporary testing praised its clean sound, headroom, and cool-running behavior. Because this is an older pro amplifier, confirm both channels, bridge mode, fans, attenuators, and all output connectors work before buying; with that check passed, USD 500 is an attractive entry into serious power.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Pro Audio Technology, known as PRO, traces its origins to 2004 when founder Paul Hales, a veteran of QSC Audio, established Professional Home Cinema, LLC in the United States. Hales aimed to bring genuine professional-grade audio into residential spaces, revolutionizing surround sound with loudspeakers and DSP amplifiers designed for high-end home theaters. In 2010, the company rebranded to Pro Audio Technology to align with its evolving strategic vision, while retaining its core focus on installed systems.
The brand specializes in professional-style loudspeakers and DSP amplifiers/processors tailored for residential custom installations. These components emphasize scalability, precision, and integration, often forming complete systems for immersive audio. PRO later expanded through its sister company, Theory Audio Design, adapting PRO technology for broader home audio applications without venturing into consumer categories like headphones, turntables, DACs, or cables.
PRO holds a niche boutique position in the high-end market, favored by A-list celebrities from the movie and music industries, sports figures, and global leaders for their private screening rooms. Its reputation rests on delivering pro-audio performance in domestic settings, prioritizing reliability and sound quality over mass-market appeal, making it a discreet choice for discerning buyers seeking uncompromising installed systems.
