Easy, fellas.

Dynamic range compression isn't simply for commercial relief. That's just the easy sell dolby and audyssey are pushing.

I just recently upgraded my bedroom Denon unit with audyssey dynamic volume, and it's a must for watching movies at night when the kid's asleep. Now I can hear the dialogue without the walls shaking from the kabooms.

Some manufacturers have implemented DSP modes like "night" and "midnight movie" in the past, but they aren't as effective as ADV in my experience. I believe it was absolutlely worth the $100 price of entry.
