Nothing quite like a really good Hi Fi - close your eyes and you could be there :-).
In my experience a really good HiFi playing a well-engineered recording will actually sound a great deal better than the live sound in many auditoria - the sole exception for me being listening to David Gilmour at the Royal Abert Hall, where the sound was utterly sublime.
Sadly for me, but rather beneficial to my wallet, these days my hearing is pretty much shot so I'm perfectly happy streaming AAC to the active monitors in my studio..
