The concept of "accuracy" is misleading completely here...
Accuracy in electrical engineering is not accuracy in digital engineering nor accuracy in music experience nor accuracy in physical acoustics nor accuracy in psycho-acoustics perspective... And accuracy for audiophiles is not any of these different accuracy concepts, it is most of the time gear choices related though not musically and acoustically related first and last ..
It is why we must study fundamental basic acoustics and psycho-acoustics concepts to understand what we spoke about speaking of "accuracy"...
Accuracy is most of the time a design marketing keyword used most of the time coming from electrical engineering measured specs or from digital audio engineering coming from Fourier analysis...
An audio system well embedded must sound NATURAL not "accurate"...Musical not "detailed"...
And all this it is not grounded on our tastes for some gear component or branded name so much as grounded in acoustics knowledge and controlled factors in a general sense of the word including psycho-acoustics when we learn how to embed an audio system nevermind his price ...
