Actually......it doesn't necessarily sound larger with a human orchestra. It can in fact, very often sound quite a lot softer in amplitude when it's live. I can be very surprised when sitting at an orchestral concert and getting attuned to the live, rahter than sampled sound. It's not so much a larger sound but a different sound.
The trouble with sampled sound is that very often it can be unrealistically too loud. Especially certain types of string sound like staccato. Some of the staccato things you hear on a sample based recording are almost impossible for a live section of really good players to reproduce.
What you get with a live orchestra of good players is an organic sound that is impossible to reproduce with samples. It's impossible and that's all there is to it. That is not to say that a sampled recording is not as good as etc. It's just different and then it's simply down to personal taste. For example - is this live? Yes it must be. But could a good sample operator reproduce this piece of music and make it sound the same. Doubtful but there are some good sample people out there.
of course you have to take into account that this example is a recording - and not actually live. Or is it? Or is it in the studio and then edited? Hahahaha.
And than after all that - are samples added to the recording? Or is it a sampled recording in the first place? Hahahahah.
Incidentally is there a difference between New York and Reno? I thought these were figment places and merely sampled for the only real place in America......HOLLYWOOD!!!!!! Hahahahaha.
