After updating to the latest firmware (1010.5), there seems to be a distinct drop in punch and clarity regarding the sound quality, and sounds somewhat compressed, be it in adaptive mode or anything else. I've tried everything - resetting the soundbar and having channel volumes exactly has they were, have gone through the process of updating the subwoofer and rear speakers, etc, etc. It's not connected to a Samsung TV, so comments about settings regarding a Samsung TV would be redundant. The settings on my TV are as they were before the update. I have messaged Samsung on their Facebook page, but they said that they're unaware of any problems regarding the firmware. Having read of this problem experienced by others on other message boards, there is obviously some change regarding the sound quality. I'm not sure if anyone can help, but I would hope that Samsung looks into it and rectifies it with a future firmware update.
