Welcome to Geocities - ec1288 website. ec1288 website publishes DIY HiFi Audio articles for the interests of the DIY audio enthusiast. Most of my projects are targetted on hard to find or expensive hi-end stuff. Reason being they are no longer in production or too costly to own them. If you really want to own them at a fraction of their retail price, you have to DIY. These completed stuff can really sing and has a way of soothing my soul and lifting me out of stress and tension when listening to music in my spare time, especially after a hard day work in the office. I could not imagine living without them as they play excellent music.
