There is a surefire way to improve the look and feel of any audio device: add vacuum tubes. These ancient electronic valves drip with nostalgia. Traditionally only high-end analog audio devices employ vacuum tubes as audio nerds proclaim they produce a richer, warmer sound. But Samsung is smart. They know that simply adding several trivial vacuum tubes to an otherwise mundane wireless speaker will increase its appeal (and justify a higher price tag). It’s working on this wannabe audiophile. I want this speaker.
