The Ultra-Fi webring is dedicated to unique, deeply personal, extreme, and even bizarre expressions of audio reproduction. Special emphasis is placed on DIY and homebrew vacuum tube amplifiers, speakers, and other equipment, and the collection and restoration of classic analog recordings. If your idea of "high fidelity" is THX-certified and purchased at the local audio salon, this is NOT the ring for you.
