diminishing returns does not mean lack of positive returns, that last few percent improvement may well be worth it for those who choose to pay for it - this applies for many many fine things in life, not just hifi
Sorta agree and disagree as this is mostly personal. If I would have known the last few percent improvement cost 6 times more than my first system, I wouldn't do it. Yup, it's my fault as I pulled the trigger without carefully evaluate "what kind of volume I want to listen to most of the time". While my new system gives me better clarity but I really need to crank up the volume to enjoy it. At low/normal volume, I would prefer my old system as it is way cheaper. I guess there's that word..synergy when you've found it.
