Eleven Audio XIAUDIO K DAC R-2R Digital to Analogue Converter

2 Years Local Singapore Warranty.

In music theory, the key is a group of pitches, or scale, around which a piece of music revolves. Key is tonality, and relates to the colour and emotion of the music. For example, the key C major is white, innocent and pure, E major is orange, warm and energetic, and A minor is turquoise, gentle soothing sadness like a rainy day.

K DAC is the key point, it’s the core of an audio system. XIAUDIO uses a custom R-2R ladder developed exclusively for them by Soekris of Denmark. This method of digital to analogue 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 colours 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.
