Dear Cinellipro: IMHO is only a distortion that apeal to some people but been a distortion it is a coloration that was not when the recording microphones pick-up at the very begin of the recording.
It is a false colorations that IMHO has no sense that so many people " die for it ".
When was the last time that any one of us heard a violin concert ( live or other instruments. ) seated at 2-3 meters from the player and heard it that warmth?, because I attend to not less than 60 times a year to listen live music and till today ( in the last 25 years. ) I never heard that warmth.
IMHO music is everything but warmth, at least in the audiophile warmth meaning.
Warmth IMHO is only a synonimous of a distorted audio system.
Maybe I'm wrong but this is my take about.
Regards and enjoy the music,
Raul.
