NuForce has just launched the NuForce S3-BT, a line of high-quality bookshelf speakers that tout Bluetooth 4.0 as one of its main selling points. Most Bluetooth speakers tend to pale in comparison to their analog counterparts, but NuForce is confident its apt-x and AAC codecs will provide CD-quality audio even to the most discerning audiophile. If you're unconvinced, NuForce has also included a set of analog inputs plus the company's own Air DAC wireless system for slightly higher quality audio streaming.
