Charles, I'm very happy to see today's development, as referenced above. If I may say so without being presumptuous, IMO your posts are consistently among the most perceptive, knowledgeable, well balanced, and (unless circumstances warrant otherwise) gentlemanly posts to be found here.
Joe (Trelja), thanks for the response. I did some searching to see if I could identify anything that might account for the amazing diversity of opinion about the Acoustic Zen speakers, perhaps such as impedance characteristics that might make their performance unusually amplifier dependent. But to no avail whatsoever, although I couldn't find a measured impedance curve.
One of the things I looked at in the course of that research was the
technical information page of the manufacturer's website. Unfortunately, what I found were the same three paragraphs repeated 15 times! Presumably the speakers were designed with greater attentiveness :-)
Best regards,
