The law of diminshing returns?

@kerrybh 

I'm with you on your first paragraph, but you lose me after that.

Surely, one man's doubling of performance is another man's achieving incremental gains. As far as I am aware, there is no objective way of determining which man is correct.

It's a matter of quality not quantity. There's no such thing as a sound quality meter.

@newton_john  I agree with you, I think we are saying the same thing although I may not have articulated it very well. The point I was trying to make is that people in the hobby have a different stopping point for the resources they are willing and/or to invest to achieve what to them, is subjectively better performance. And that’s an individual thing where there is no objective right or wrong- just a matter of how we, as individuals, assigned value. 

BS article. 
No recognition for sound quality. 
 

Diminishing returns is not about the absolute level of money you spend on your system, but whether the last dollar you spent gives you the same increase in sound quality/listening satisfaction as the first dollar you spend.  Typically going from a $1k system to a $10k system is a greater increase in fidelity than going from a $90k system to a $99k system.  I think this observation applies regardless of your audio goals and income level.
