So much the better if my words seem to you in favour of the 3000, my ears tell me something else.
If you use Photoshop for example, you know that accentuation or sharpening can improve the rendering; if you force the setting it will cause a clear outline... whether you accept it or not...
It seems to me that the 3000 has received a similar treatment with this "black background" which is finally very "audible" and which makes each sound sharper, even more accentuated in the treble... and which everyone will feel differently...
The SP2K does not have this "black background" and, to my ears, provides a more realistic sound, at least and in a sensitive way, more melodious.
If this is confirmed with the Phonix, I will regret some technical improvements, but personal listening pleasure comes first.
