New Speakers ... Can't Stop "Listening"

I’ve had my new JA Pulsars for about a month now, and something really strange has happened ... I’m actually interested in "listening" to the music. With my old B&Ws, I’d put on the system and read or surf the internet; being "involved" with the music typically was not something I had experienced. Now, reading a magazine or surfing the ’net is virtually impossible. It's almost as if I'm compelled to pay attention. I never knew I could be so engaged by my system. Other than greater detail, what am I hearing now that I hadn’t heard before? Has anyone had a similar experience?
