I think I'll just invest in the sound reinforcement system the Moody Blues used at an outdoor concert we attended a couple years back. That was pretty dynamic. My ears are still recovering.
I'm quite happy with my compromised music delivery. It sounds wonderful and quite dynamic at the levels I do listen at. Not like live music, I've been to enough concerts to understand that but somehow I manage to enjoy it all the same.
It'll be interesting to see how well the things sell.
It would also be interesting to have some of our resident amp (or speaker) manufacturers pipe in on the subject.
