Interesting example of the -- loud is good, but louder is better -- prime theory of my youthful listening years.
In spite of that theory, I recall being blown away by the first pair of electrostatic speakers I heard in the 70's. They were Janzen's. These were the first speakers that provided the mid-range transparency that I was seeking but had never heard/found.
However, the Janzen’s literally sparked when played loud, which meant they didn't come close to passing the manditory Match Test".🙂 Thus, I went on to purchase ESS Heil AMT3 (Rockmonitors). Whether the Heil's dual-10" woofers in each speaker would have passed the Match Test I don't know.
Nevertheless, I never forgot that inviting, lovely Janzen electrostatic sound. Years later, when I learned that Dr. Roger West was involved with Janzen’s R&D, I headed in the direction of Roger’s SoundLab full -range electrostatic speakers and have never looked back.
