Open Box... But Working Perfectly!

To give the AD4 true audiophile performance, Starke Sound’s electronics team developed the innovative NS600 module, raising its sampling rate to 600 kHz and employing a pure analog power supply. Combining the high efficiency of class D and the warm sound of class AB amplifiers, AD4 also offers the flexibility of 4-channel or bridged 2 or 3-channel operation. The AD4 is a perfect combination of usability and performance.
