Our Testing Procedures
Measuring audio components
We test the audio components we restore to ensure they perform at least as well as expected. This is both an overview of our measuring procedures, and an attempt to make clear exactly what is being measured.

Answers to some frequently asked questions.

During the 1960's and 1970's Luxman produced many examples of fine high quality, high end audio components. Like many other manufacturers, for the most part the quality of their products declined during the 1980's. However, Luxman is again producing very high end, exotic (i.e, expensive!) amplifiers (both tube amps and solid-state), preamplifiers and digital components. The swank B-1000F monoblock power amplifiers will set you back in the neighbourhood of $55000!

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!
