John ,

Is that Dayton Audio DATS V2 System accurate enuff to measure imp magnitude and phase ..?

Yes. I have compared it with MLSSA's impedance measurements. I also compensate for the test lead impedance and calibrate it every time I use it.

AXPONA and really liked the presentation. The bass foundation was robust and I was impressed with the coaxial ribbon midrange and tweeter. Imaging in the smaller room was very good but the star of the show was vocal transparency and distinctiveness. Whether attributed to the driver technology, uncanny lack of cabinet resonance coloration or a combination of both, I was captivated.

I appreciate that you provided well detailed descriptions of your listening room, loudspeaker placement, toe-in, propagation distance, etc., which is useful context. Not all loudspeaker reviews provide this, but should.

Why do so many expensive speakers have such mediocre measurements? I don't get it, John Dunlavy built speakers that measured far-better than this 30 years ago.

They put more effort into looks than sound quality. Some argue, without a clue, that measurement don't matter. Well, they're wrong! And it's not just about the frequency curve as they say, identical ones can sound totally different. The spectral decay is very telling, the intermodulation response as well and many more, and all that comes down to the drivers quality and crossover components and design quality.
You can buy KEF R3 META and if you open it up, you will notice how bad the crossovers are...
I would rather have a good MDF case and good drivers/crossovers than fancy looks. BTW, the end price for a product like this is about 4 times what the production company gets for it... do the math.
You invest in good drivers and components for about 25% of the final price and you would absolutely going to get much better sound. It's strange people pay this much for poor quality speakers...
