There are three systems in the line-up. First up is the Samsung DA-E750, which is a self-contained stereo audio dock system targeted to iOS and Galaxy Smartphone users.
In these systems, the vacuum tubes are used in the preamplifier stage for the two front left and right channels, supported by digital amplification to round our the rest of the channels and power the speakers.
In addition, both systems feature built-in Blu-ray/DVD playback, built-in WiFi (which provides the ability to streaming content from the internet and DLNA-certified devices), and Samsung's Smart Hub, which makes the navigation of both off-line and on-line content easy. The HT-E6500W provides a 5.1 channel configuration with compact bookshelf speakers, while the HT-E6730W provides a 7.1 channel experience and the inclusion of two "tall-boy" speakers for the left and right front channels that also feature a speaker tilting function that can direct sounds upwards for more emphasis above the listening position.
