Yes, we should be in agreement and respect that diminishing return (DR) point depends on the individuals, disposable income level and other factors. However, if the point is so widely spread and subjectiveness driven, the DR therory is no longer valid. Basically, every price point and the corresponding performance cost ratio can be the sweet spot. Mr. A is fine with wiim, Mr. B is fine with iFi ZS, Mr. C is on the Mercury streamer, Mr. D is on the Auralic, Lumin, Aurender, and on and on. There is no diminishing return by this broad statement.
So, let us not talk about DR. Don’t talk about the big word that we could not handle. Just enjoy the music with the system we are content with. Happy new year, everyone. 😊
