At A$750, this Monster Audio HiFi ET MA9 asking price sits just above the 75th percentile of A$684 for recent AUD comps, making it ambitious compared to the typical used market where the median is A$156. For a buyer, this price is hard to justify unless the unit is pristine, original-owner condition with full accessories, because you could likely find a median-priced MA9 for A$156 or a strong deal under A$109.
The HiFi ET MA9 is well-regarded as a new reference-level DAP in the premium segment, offering enthusiast-driven design closer to iHiFi players than mass-market brands. Its upside includes rare multibit architecture and compact form, but at A$750—well above the median—you must verify condition, battery health, and included cables before committing. If it’s clean and complete, it’s a niche buy; if not, the price is a warning.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Monster is an American audio brand founded in 1979 in San Francisco by Noel Lee, an engineer and music enthusiast who started the company by developing higher-performance speaker cable. That origin story still defines the brand: Monster built its name in the early cable era by arguing that better materials and construction could make a real audible difference, especially in home hi-fi and AV setups.
Today, Monster is best known less for traditional audiophile separates and more for consumer audio accessories and connected gear. Its lineup has included audio and HDMI cables, power products, gaming accessories, headphones, speakers, and assorted home-entertainment accessories. It is not primarily a maker of amplifiers, turntables, or DACs.
In market terms, Monster sits closer to the mass-market and mid-tier consumer-audio space than to the high-end audiophile or boutique collector world. It has strong brand recognition and a long heritage, but its reputation is built on broad retail reach, licensing, and practical connectivity products rather than purist reference components. For buyers, Monster is a familiar mainstream name rather than a specialist high-end hi-fi marque.
