Howard, I'll offer another take on why some of the vintage gear is musically the equal of newer stuff - good engineering. Before the modern computer era it was more likely that talented engineers would end up working for an audio company than today because the electronics industry wasn't as diverse as it is today. Today the most talented engineers usually work in the communications and computer industries because that's where the most interesting work and the best pay is.
So, in the past the guy responsible for designing an amplifier, for example, for a major electronics company was likely one of the best guys you could find for the job - a true analog design guru. Nowadays the more likely person to be given this job is not as much of an analog design specialist. He relies upon the manufacturers of the ICs he uses to do the bulk of the engineering and he simply implements the recommended circuits found in the databooks. He also probably doesn't have as much experience as the engineer that designed the vintage piece did. He is able to achieve good results because the components are better, not because his skills are better. The vintage guy achieved good results with components that were not as good. This required more skill. Evidence of this skill can be found in vintage pieces that are still working fine after 30 years or more. They were designed to be reliable, not disposable as so much of todays consumer gear is.
I don't mean to say that there are no talented engineers designing audio gear anymore. There certainly are. They are more likely to be found in small companies as owner/designer. These guys have a true passion for their work. Jeff Rowland is a perfect example of one of these guys. I am curious as to why you think Rowland has been marginilized, though. I have always respected Jeff's work and have voted with my own dollars as my system is based around Rowland gear.
