Since the D430 offers an Optical output, I would have to say that any of the Samsung SoundBars will be more than compatible and sound great with this TV. That said, choosing which SoundBar would be best for your setup is really up to you. Although I could tell you that the top of the line model, the HW-E551, is the best you can buy, it may not be the best for your application or budget. I suggest taking a look at the Samsung SoundBar page and use the "Check to Compare" option to find the right SoundBar for you.http://www.samsung.com/us/video/sou...
