Διάβασα αυτό σε ένα thread στο audiosciencereview σχετικα με τον "λαμπάτο ήχο". Είναι ο βασικός λόγος που υπάρχει το hi-end φαντάζομαι.
Λινκ: https://www.audiosciencereview.com/forum/index.php?threads/if-tube-sound-is-a-myth-why-tubes.8656/Like other senses, our hearing gets compensated by other information that brain has. There are little muscles below our hair cells that sense the sound. The brain use this muscle to hear what it wants to hear more clearly. This is why we can talk to other people in noisy environment.
When we see a music coming out from tube amp, our brain emphasizes certain sounds in accordance with our bias. Someone who thinks that tube amp sounds 'warm' will focus on bass. Someone who thinks that tube amp has its own 'texture' or 'harshness' will focus on highs.
This also means that no matter you intend to make tubey sound or not, if there is a tube or analog VU meter on top of the amp, people will 'hear' tubey sound. The designer's choice will be the color of LED to make tube glow.
