The SoundStage! Network's Preamplifier-Measurement History with BHK Labs

Following the introduction of our highly successful loudspeaker-testing program with Canada's National Research Council (NRC) and subsequent amplifier-testing program in 2002, the SoundStage! Network began its preamplifier-testing program in late 2004.

To conduct these test we commissioned BHK Labs, the same laboratory who does the Network's amplifier tests, headed by Bascom King, well-known design engineer, consultant, and technical writer for such magazines as the former Audio.  

Each preamplifier is tested using the Audio Precision System Two, and each preamplifier goes through the same type of testing program to ensure consistency, quality, and comparability in the test results.

With the cooperation of Canada's National Research Council (NRC), in the year 2000 the SoundStage! Network began measuring and publishing objective measurements of loudspeaker products -- a first for online publications.

The NRC's legacy of producing accurate loudspeaker measurements goes back decades. Literally thousands of speakers have been measured in their facilities since the '70s, and they are one of the few facilities in the world with the resources and expertise to conduct such tests.

The NRC facilities have, of course, been continually upgraded and today it's a state-of-the-art laboratory that includes an anechoic chamber, reference-grade test equipment, experienced staff, and a standardized process that is used consistently for all products. The end result are measurements that we feel are a benchmark for the industry, and useful for anyone wishing to obtain accurate, objective data about loudspeaker products.
