The Samsung HW-T550 has a lot of sound enhancement features, although it lacks room correction, which means it may sound a bit differently depending on the acoustics of your room. On the upside, it has four additional presets: Surround Sound, Game, Smart, and DTS Virtual:X. The Smart preset uses DRC (dynamic range compression) and acts as a dialogue enhancement feature. You also have access to a 7-band EQ with a few commands on the remote.
