FAQ
Answers to some frequently asked questions.


Founded by Avery Fisher, Fisher (or The Fisher) made quality audio components in the 1960's and 70's. The vacuum tube components, in particular, are popular with collectors. Some time later Fisher was purchased by Sanyo, who ruined everything.

Regardless of how good any individual component specs out, your audio system will only perform as well as the weakest component in the system. The best exotic loudpeakers available will sound mediocre when driven by a gutless power amplifier. Likewise, a powerful, expensive, accurate amplifier driving cheap, poor quality speakers will sound cheap. Superb audio systems are assembled by collecting superb components. When it all finally comes together, you know it!
