TONE

Yup.  That's one of the main reasons I go to live music--I want to stay familiar with the sound I've trying to get (or allude to!) at home, and am willing to put up with the increasingly boorish behavior of contemporary audiences to do that.   

I doubt there is any way to 'reproduce', say, the sound of a violin in a concert hall on a stereo system in your living room.  Even listening to your system against a violinist in the room doesn't do much, because that's not the sound you want.  If you had an opera singer in your living room, you'd probably blow your ear-drums out.   Even if you could 'exactly reproduce' the sound of a violinist in a concert hall in your system, you would only be working with the way it sounds from one particular seat in one particular concert hall.  (Maybe in the future we can fine-tune our stream:  Heifetz, Beethoven VC, Carnegie Hall [1940s version], mezzanine row G seat 112.  But until then, we're stuck with great sounding smoke and mirrors.)
