New in 2012, Samsung's patented vacuum tube amplifier technology . Vacuum tubes, which use a long-lasting heated cathode inside a glass bulb to amplify sound, are suppoesed to offer a warmer, more natural sound compared to conventional audio systems utilizing transistors.

The vacuum tube is also combined with a digital amplifier, which delivers clear sound and reduces unnecessary harsh sound distortions.

The DA-E750 can be used with a Galaxy S II smartphone as well as Apple iOS devices, thanks to a dual docking structure. Its 2.1-channel woven glass fiber speakers and built-in subwoofer deliver 100 watts of sound with enhanced bass. Samsung's AllShare Play can be used to share multimedia content between the audio dock and compatible smartphones, tablets, cameras and computers and AirPlay to stream audio from iOS devices. The DA-E750 also includes analog (composite) input and connectivity via Bluetooth to MP3, WMA and WAV files from a broad range of devices - thumb drives, portable hard drives, music players and mobile devices.

The DA-E750 combines classic design elements with a touch of luxury. The sleek high gloss wood finish is available in either mahogany or piano black, which is accentuated by the warm glow from the vacuum tubes inside the docks when in operation. For added convenience, the audio dock will simultaneously charge the Galaxy S II or iOS device while streaming music.
