That wattage comparison is a true apples/oranges issue when you're comparing different brands. But within the same brand, and same lineup, wattage differences are accurate enough to actually mean something. That said, I also appreciate higher wattage systems for lower volume dynamics more than just being able to shift cinderblock's, so for me there is a true benefit of having more power. That said, I don’t want to drop more money if I’m not going to notice the difference. Problem is you can’t find a store in town anymore that demo’s high end receivers…of course they all lost business to internet sales…but I do miss being able to compare side by side without taking home two units…
