Description K DAC is the key point, it’s the core of an audio system. Eleven Audio uses a custom R-2R ladder DAC. This method of digital to analog audio conversion has become quite popular in high-performance audio, particularly with more critical headphone systems where the ability to listen to music in a highly linear fashion is key. Subtle nuances between shades of tonal colors simply flow and more accurately define the artists emotional intent hidden within. Music flows smoothly from this K DAC with the beauty of a very finely tuned instrument, maintaining live harmonic structure and vocals in a way XIAUDIO products are so well known for. K DAC reproduces the delicate nuances in your music like no other near this price point. Combine the K DAC with their matching Broadway Balanced headphone amplifier for a compact, high-performance audiophile desktop/gaming headphone audio system.
