Oh god, i was thinking the same today after seeing a few videos. Since i bought my S2 two months ago I was pretty sure that my S2 was louder than my ipad, but somehow that perception changed this days.... might be the last firmware update? Pretty strange because if that was the case a lot of users would be complaining.
It is not much better with enhancements off and it definitely has degraded with firmware updates. I completely agree that it used to have better sound than Ipad Eljoe.
Netflix won't even work with enhancements off.
Hopefully Microsoft reads these forums.
