Excerpt: Meet the latest of NuForce's audiophile-grade audio devices, the Cube . No this is not the Allspark in disguise, and although it looks cute, it'll tear your ears apart with room filling sound. What is it? The Cube is first and foremost a portable speaker designed to serve up big audio despite its tiny size. If that's not enough, the Cube is also an all-in-one portable speaker, headphone amp and at your computer desk it serves you as a USB DAC.
Conclusion: I do. It delivers good sound, which you want from any speaker. It is perfect for taking your sound with you and it works very well on a crowded computer work station. An extra bonus for me — I use an external monitor and therefore keep the lid to my MacBook Pro closed which muffles the sound. Now I keep the Cube Speaker plugged in and am ready for any time I need instant sound, including Skype calls.
