The Yamaha YAS-209 is a better overall performing 2.1 setup than the Samsung HW-T450. The Yamaha is a bit better built, and it has more physical inputs including a Full HDMI In, so it can support Dolby Digital. It has a more balanced and neutral sound profile, and its center and surround performances are better too. While it can’t get as loud as the Samsung, it can also reach its max volume with less thumping and compression artifacts. Besides Bluetooth, you can also stream to it using Wi-Fi, which is nice, and it supports 4k @ 60HZ passthrough.
