I just don't understand how these two statements are linked. To reproduce the sound of a violin you need a violin, not a loudspeaker. A loudspeaker reproduces the impression of a violin which must be approximate, starting form the fact that the recording process itself introduces inaccuracy. In an orchestral recording, it's possible that some instruments don't make it to the vinyl groove (or digital bits) just because they aren't picked up by the microphones.
Speaking of orchestral music (and other so called classical music), surely the point of a hifi system is that it creates an illusion, but an essential part of the illusion is that it shouldn't appear to be an illusion.
As it happens, yesterday evening I was listening to literally the best sounding system I have ever heard, where the illusion was so compellingly recreated I really felt I was listening to (a) Vivaldi played in the Academy of St Martins in the field and (b) Belshazzar's Feast performed in Kingsway Hall. But it was the delicacy of the former performance and the visceral excitement of the latter which was so truthfully reproduced. Given the quality of the system I'm sure it satisfied pitchwise. But would it have mattered to my emotional response to the music if it hadn't?
