I've read that they are not all the same...that some are "cleaner" than others. For example, in this thread: http://www.hometheaterforum.com/htfo...threadid=52005 Saying that the 100 watts/channel really aren't 100 and the HK 50 watts are apparently better. How can I read specs to know what I'm looking at. There is no standardization to how manufacturers present their specs? Any info in this area is appreciated.
