With a 60" 4K Samsung TV, you are potentially selling yourself a bit short with a 3 or 4 series soundbar. If you step up 1 more level to HW-K550, there is a noticeable improvement. More power, but more importantly: a discrete centre channel speaker within the soundbar for more separation of sound and better vocals from the actual centre of the speaker.

Nothing wrong with the less expensive models, but the 550 is definitely a step up.

Meanwhile: c'mon management team, lets make some noise.
