You'll also find built-in Wi-Fi and access to Samsung Apps.
Samsung has been making some changes to its home theater systems in the last few years and this year's models are certainly taking things up-market a bit.
The company's new home theater systems - the 7.1 channel E6730W and 5.1 channel E5500W - include more than just the traditional receiver and speaker combination. For starters, they pack a Blu-ray player that does 2D to 3D conversion so you can enjoy your existing Blu-rays with a bit of extra pop.
More interesting though is the addition of tube amplifiers to the higher end E6730W. The system combines "The crystal clear sound quality from a digital amplifier with the warmer tone qualities of vacuum tubes." The tubes are visible from the front and top of the system too, giving you a piece of hardware that's bound to impress some folks.
