This is a bit irrelevant, but while A sharp and B flat are the same key on a piano and many other instruments (and indeed are the same in an equal-tempered tuning system), I am really not convinced that a virtuoso violonist or cellist, or an opera singer, would consider them as equivalent and would play exactly the same tone.
