Vs: Striimerist muusika kuulamine, olgu selleks siis Tidal, Qobuz, või koguni Spotify
Ilmselt kõik, kes TDA1541A-d ei oma on rängalt st 10 kordselt moonutuste kuul(a)misega petta saanud.
In electronics, the subjective correlation between Total Harmonic Distortion (THD) and what you actually hear is close to zero. After all, a low-fi rack-stereo receiver has far lower THD than the best-regarded triode amplifier. Does that mean that "all amplifiers sound the same?" No, certainly not with high-performance speakers. Is the converse true — that measurements are meaningless? No, that’s not true either; there are plenty of amplifiers with terrible measurements that do indeed sound terrible.
The fault is not with the subjective perception of the listener, but rather in the measurement itself. Nothing new in that; you can measure all you want, but a mass spectrometer isn’t going to find a lot of difference between lunch at a high school cafeteria and the best dinner at a four-star restaurant. To foolishly assert that the mass-spectrometer is right, and the restaurant customers are all deluding themselves with some kind of "placebo effect," is an example of simple ignorance trying to cover its nakedness with the fig-leaf of Science.
The restaurant customer — or dedicated hi-fi enthusiast — have been right all along in their subjective perceptions; it’s up to the serious designer to find out what’s going on beneath the surface, and not indulge in vague pseudo-scientific hand-waving about "euphonic distortion" and "placebo effect." All we can say for certain right now is that simple THD figures are not the right measurement for electronics!
