Neuroscience probably has not gotten to that point, but I don't know  
that much about neuroscience.  But I do know enough about science to  
tell you that humans cannot tell the difference between such things  
in double-blind tests.  So you don't need to know anything about  
neuroscience to make a useful judgement about this.

In a carefully controlled environment, with very nice equipment,  
something like 99.5% of people cannot tell the difference between  
things like tube and transistor amps, digital or analog audio, or  
electronic circuits or digital recreations.  Try it yourself sometime.

Double-blind is the key.  Humans are extremely sensitive to nuances  
that we give off.  So to do it right, both the listener and the  
controller of the experiment cannot know about which source is which.
