The SoundStage! Network's Amplifier-Measurement History with BHK Labs and Our SoundStage! Audio-Electronics Lab

Following the introduction of our highly successful loudspeaker-testing program with Canada's National Research Council (NRC), in 2001 the SoundStage! Network began its amplifier-testing program. Originally, tests were done by BHK Labs, headed by Bascom King, well-known design engineer, consultant, and technical writer for such magazines as the former Audio. BHK Labs tested amplifiers using the Audio Precision System Two. Beginning in December 2020, we brought the amplifier testing in-house to the SoundStage! electronics lab and began using an APx555 B Series analyzer.
