I personally do not nor have nor ever had the ability in assigning a numeric value to an increase in performance. It either is one of two things
1) a lateral move, maybe different but not and improvement but may initially be perceived as an improvement because it's different.
2) an improvement that can vary from small but noticable to substantial but is quite apparent.
I have had conversations with a manufacturer that places a numeric value on the % of improvement he has made on his products. He actually told me that I could expect a 135% improvement over what I had to what the current model was. I think he just added up these improvements over the years and came up with that number but it meant absolutely nothing to me other than I could expect a BIG improvement.
The law of diminishing returns to me is when you aren't gaining more enjoyment listening to music through upgrades even though they may be improvements. I don't believe there is any way to quantify it or measure it. At some point, different for some than others, it simply comes down to whether or not it is worth spending the money for the gain. When the point is reached where spending more isn't worth it, if ever (we are audiophiles after all), the law of diminishing returns has arrived.
As far as your system goes RlB61 only you can answer that question. If you are throughly enjoying the music your system makes it might be better to leave it alone until that stops happening. If you are not satisfied about something and are distracted because something doesn't sound right you have NOT hit the point of diminishing returns.
