Ralph,
I don't really disagree, except I'm still really pleased with the plane analogy:). I think we all should step back occasionally and consider what humans can and do create using our accumulated knowledge and contrast that to the some of the undefined minutiae of high-end audio.
There are many, many different amplifier topologies and philosophies and pretty much all reviews I read are positive so is there one true approach to amplification - probably not? Though each proponent probably thinks so. Add into that cost, appearance and peer approval and, I'm sure, that is as significant as a bit of 7HD.
So, is there a secret to perfect audio and how do you test for it? Until we have that answer the only examination question is measure what you can. If the results look good on paper you might think 'at least this designer has tried to be faithful to the input', if the results look poor you really don't know if the designer has studiously eschewed measurements for subjectivity or just doesn't have a handle on what they are doing.
The Volkswagon analogy doesn't quite work. If an amplifier 'looks good on paper' but is found subjectively lacking, where is the cheat? What VW did was design for good subjective performance and then cheat with a test setting to make the measurements look good too.

But then you when you listen it doesn't sound right. That's because the specs that look good on paper don't sound good to the human ear because the specs on paper aren't right.
In the case of VW, it pollutes when it shouldn't. kinda but not quite the same thing, unless like me you think that too much 7th order is pollution...
The Bottom Line is we don't measure the right things, and further, it does not like we will be measuring the right things anytime soon- see JA's response below in this thread.
VW had 3 options,Option 1: Bad ignition switch that kills ..
Option 2; Bad AIRBAGS that kills ..
Option3: Spew a little more diesel nox , harmful to ...?
VW went for option 3, fibbed about and had happy owners dancing at 800mls a tank full .... Yeah !!!!
Go Rossi ......
