This video also provides a brief tour of the ‘business-end’ of our listening room, along with our A/B switching setup. The large screen is displaying our patent-pending real time spectrum display comparing the input signal and output signals while the amplifier plays music.

Our unique computer analysis measurement system allows AEA to not only measure the performance of amplifiers while they are playing music; it allows us to “see” why one amp sounds different than another, and use that insight in designing each stage of the amplifier. The results speak for themselves. Or should we say, “sing for themselves.”
