Not sure why you would make such an assumption without any knowledge.
Well, I do do this for a living, and have heard a lot of passives with all sorts of digital and analog gear. The performance issues I listed I have heard in all of them. When I started running the math it became obvious why. So its not without knowledge.
Audio is a funny field, even if the math agrees with the subjective experience one still has to make a case for it. You are correct about the dogma (although the whole passive thing strikes me as dogma as well); years ago when I first began developing a preamp the whole balanced-line thing was already obvious. I had played in several orchestras during high school, college and post-college. What I saw there was that when the concerts were recorded, the mic cables were often extremely long; at the local college they were usually over 100 feet as the mics hung from a 'cloud ceiling' that could be raised or lowered. So this had a big impact on me as I also knew Robert Fulton, arguably the founder of the high end cable industry. He always had very short single-ended cables...
I also run a recording studio and have refurbished a lot of studio and consumer gear over the years. The studio gear is usually designed to minimize cable problems and the consumer gear is never done that way. This comes out of old tradition (and cost) more than anything else.
I don't seen the cable thing as a red herring at all. If you install the volume control inside the amp you don't have any troubles with it- a control that robbed the system of bass as a passive does not do so if its inside the amp.
