I agree that quantitative measurements are ineffectual and cause more confusion than not. People look at almost identical FR graphs and think they should be the same...but they are miles apart. Draw the same conclusion for amps and you are equally fucked. Doesn't mean measurements are bad, they are just one part of the equation.
As for all the inaccurate stuff, well very few people actually know how electrostatics operate down to the core. Even the people who build them often have no idea, they just cobble something together which kinda works so that's a good'n... Long charge time for the diaphragm? No, but sometimes yes. As for the 007 being so difficult, it's all about the capacitance and how it couples to the acoustic transmission. I also wouldn't call the 007 difficult to drive in the sense that they require heaps of power like that Hifiman ortho crap. A much more accurate description would be that they require a supremely stable and linear amplifier, one that isn't fazed by their quirks. Now this should describe any capable amp but we aren't talking about simple dynamics here so even small issues can have drastic consequences.
It really doesn't matter what amp Stax make as people will always want more. I'm kinda glad that Kevin talked me out of designing a baby Carbon as people simply don't want budget amps. I've been standing on the break the best I could but what they really want is something crazy expensive and unique.
One last thing, anybody claiming that all Chinese parts are bad are just idiots. The worst transformers I've ever used were SumR, none have ever shorted to the chassis like they did (two of them) but among the worst were also Chinese. Now the best transformers I've ever used were also Chinese. That's only because I'm willing to pay for the best, willing to go through multiple test units and let them know exactly what I wanted. Now each unit is perfect and just like every other one. Same goes for PCB's, there are some real dogs out there but once you find a place to work with that actually cares about quality you'll know that it matches anything else in the world.
