Changing audio equipment hasn't changed my musical tastes at all. In my view, a good system should play everything well, regardless of genre.
Maybe I'm lacking in imagination, but my musical tastes haven't changed significantly since my teenage years. I was into classical, jazz, folk, and prog-rock in my late teens, pretty much in that order, and I still listen predominantly to those genres in that order.
Having read something of the Grammy awards, I feel somewhat like the Judge who didn't know who The Beatles were, as I don't recognise the majority of the acts.
(Oh and I too like Diana Krall, have all her albums.)
