Audiocircle.com (English) USA based hi-fi forum, has some general audio and AV forums but the main business model of the site is centred around selling audio makers the access to their own forums on the site and thus the bulk of the forums are manufacturer specific. Homepage:http://www.audiocircle.com.
Hifisentralen (Norwegian) Norwegian hi-fi forum and auction/small ads site, although it has some music and home theatre content it is very low key compared to the hi-fi side. The site was originally set up by Jostein Berntsen as a hi-fi news site in 2000 but he was joined a year later by Thomas SŠtervadet who developed the forum, the latter is the owner of H°ium Data & Hifi AS. BTW., by 2006 the news content and articles had been removed and Hifisentralen had become a pure forum. Despite having some adverts the site is a non-commercial entry and all who work on it do so on a volunteer basis. Homepage:http://www.hifisentralen.no.
