FAQ & Tech Hifi Terms of Service

The original Tech Hifi company filed for bankruptcy in 1984. We were big fans of the original company and used to shop there a ton. We bought the name in 2010 and have all the rights to the name, logo, branding etc. We are not technically affiliated with the original company but think of what we do as a marriage of many of the ideas of the original company with a modern twist! For a full history of the company, check out the About Us page!
