HiFiShark

About this resource

HiFiShark is a search service for second-hand hi-fi, operated by the Danish company Hifishark.com ApS. Its about page explains that the service arose from the difficulty of repeatedly searching multiple equipment marketplaces with different search criteria. It aggregates national, regional and global listing sources rather than presenting itself as the owner or seller of all the equipment it finds. ^{[1] [2]}

Buyer-facing functions include searching currently active listings, browsing products by brand and viewing expired listings for price context. Users can save searches, request optional email notifications when new items appear and mark interesting listings as favorites. Expired advertised prices can inform research, but they are not necessarily completed-sale prices or proof of what an individual unit ultimately sold for. ^{[1] [2]}

For private sellers, the site advises listing equipment on a marketplace it indexes. Professional sellers can ask to have their second-hand, demonstration or bargain inventory incorporated into the index. The useful starting point is therefore a specific model search, followed by the original listing and seller information. Saved searches support longer searches for uncommon equipment, while the about and FAQ routes explain how the aggregation service differs from a transaction conducted directly on a retailer’s website. ^{[1] [2]}
