I am really pleased to rekindle my relationship with Astell & Kern. Over the years I have owned a few of their offerings. The Kann Cube has the audiophile forums buzzing. The Cube has three Gain settings and a black noise floor, which is surprising with the power the Cube exerts. The Cube has 2.5mm, 3.5mm and XLR outputs. A&K has always had delivered an excellent UI and the Cube is no exception. I just received the unit tonight so my journey has just begun.
