I am amazed by the fact that many people had not discovered that there is a difference between tinkering at random or doing it with a method ...
When you do it with a method you reach an optimal threshold acoustically some day and you are done with these level of design/cost components you were using ... You are happy with them...
You can then upgrade or not ...The cost will be very high compared to what you have now well embedded ..
Most of the times you dont want to upgrade as an obsession because when the success was reached when a method of embeddings controls is applied with many low cost components but synergetical good one , you are in ectasy listening music in an acoustic immersive experrience ... Why upgrading now ?
The cost will be very high , in my case 700 bucks headphone/speakers system to a 10,000 probably more 15,000 bucks more for improvement mainly with better dac and BACCH filters and new speakers ...
I dont even dream about it because i am in ectasy every evening ... Am i deaf and easily satisfied ? Trust me i am not acoustically easily satisfied then , my system cost is not a stopgap ...The solution is buying the good basic synergetical components and after that a method to solve embeddings control problems , nevermind the components cost...😊
Tinkering at random and upgrading at random in buying spree is not and was not my hobby save the 10 years during which i learned the hard way what i must learn to create my acoustic heaven ...The first in my 72 years old audio journey ....
My situation improved the day i begun to read about acoustics and the day i dare to try to modify my 9 headphones because they were all artificial sound nevermind their types and i tried to experiment in my room ...
