Samsung HT-D6730W is a good choice when you are looking for a complete set of you home entertainment unit, it has 2 HDMI in, internet TV, Blu-ray player that feature a 3D technology, and also a wireless rear speakers. But it is also a very high price, if you are looking for something cheaper but still match in term of specification (read the spec of Samsung HT-D6730W here),
you may want to check out Sony BDV-E780W and this is its specification : due to fact that Sony BDV-E780W is almost 50% cheaper than Samsung HT-D6730W, I think it offers great features including 3D Blu-ray player, internet TV features Netflix and also internet radio feature Pandora, 2 HDMI inputs ! and also rear wireless speakers ! So, actually you can get what Samsung HT-D6730W offers with almost a half price with Sony BDV-E780W, the question is what is missing in Sony BDV-E780W ? The answer is front speakers, while Samsung HT-D6730W offers great tower style front speakers that you can use it for music listening, Sony BDV-E780W features satellite speakers that is not so good for music listening due to the fact that they lacks of a mid speakers. Maybe you’ll need to ask yourself what do you really want, if you are not so serious about the audio quality for music listening, I think Sony BDV-E780W is a good enough choice.
