Noted turntable manufacturer Victrola just announced the Soundstage speaker at CES. This thin little doodad actually sits underneath turntables, removing the need for a full stereo set-up. The Soundstage isn't the first speaker that offers this functionality, but this one has tech-forward features.
It offers multiple connection options, including Bluetooth. Many newer Victrola turntables can do Bluetooth streaming, so adding this speaker to a setup would be extremely simple. Otherwise, companies offer Bluetooth receivers for turntables.
