A lot of love went into the well polished high-end, tube-powered DA-E750 audio dock and we think it should be impressive enough to win a nice spot on your wish list. This handsome boom box features glass fiber speakers and vacuum tubes to bring you natural and harmonious sounds. What's more, the device can be linked to your Samsung Smart TV* or mobile devices… wirelessly!
Yes the DA-E750 is gorgeous, but the development of it wasn’t as glamorous as you might think. As the DA-E750 was a first of its kind from Samsung, We had to source the best from each field and start from ground zero. Let’s meet the engineering heroes who worked together ‘heading (yes, banging your head) on bare ground’, as we jokingly say in Korea when you try to do something very difficult from scratch, to make this project a reality!
“We needed to make it last” (AV team)
The standout feature, other than this machine’s looks, is Samsung's proprietary vacuum tube / digital amplifier combination, which is said to offer both warm and clear sounds — "the best of both worlds."
An audio dock needs to do its job of delivering exceptional sound quality to win users’ lasting love. This was of course a key factor in developing the product. I can’t tell you exactly how we did it due to security reasons, but I can at least bring you a quote from one of our principal engineers.
While tuning the hardware to produce the best of sounds was one thing, engineers were also concerned about making it ‘Samsung sturdy’. Some vacuum tubes won’t that last long but that would be unacceptable of a Samsung product. Our goal was to make an audio device that can last for over ten thousand hours of listening (typically more than 10 years). A lot of effort was put in to ensure long stable use.
Another measure to help use the DA-E750 longer was to make it work even in unfortunate circumstances where the vacuum tube doesn’t. This is possible because this audio dock uses a combination of both vacuum tubes and a digital amp. The DA-E750, thanks to a patented piece of cutting edge technology, automatically recognizes it when a vacuum tube has a problem and switches to using only its digital amplifier. Though we recommend you replace the vacuum tube when it breaks, you can still enjoy great sounds tuned by the digital amp until you can replace it.
"What about an audio dock that can be connected to a TV wirelessly?” (TV team)
This idea actually came from the top. HyunSuk Kim, Executive Vice President and head of the VD Business. Our engineers agreed it’s a good idea and came up with SoundShare, which allows the DA-E750 to be connected to Samsung Smart TVs via Bluetooth*.
The sound output of a TV is normally about 20W but DA-E750, with its two 20W speakers and 60W subwoofer can bring out a maximum total of 100W. Talk about being blown away!
"It’s gotta work well with smart devices”
To include a docking system for the Galaxy series smartphones, the AV team worked with the R&D team that took part in Galaxy projects. It wasn’t that easy but all went well and the DA-E750 can accommodate your Galaxy or iOS handheld device of choice via a dock, or, for those that like being truly wireless, stream audio via Bluetooth 3.0, AllShare Play or Air Play.
Pioneering new grounds
As mentioned earlier, this is the first wireless audio dock we made, and thus it wasn’t that easy making this product. These are some of what the insiders had to say about it.
