K DAC

為什麼叫K DAC?

K來自Key這個詞。在音樂中,Key代表調性。我們常說的C大調白色,E大調黃色,
a小調純藍色。Key非常影響音樂的色彩。
在音樂中,Key也用於代表某個調式的主音。這也符合我對解碼器(DAC)在音響系統中的定位。 我一向認為,音響系統中,解碼器(DAC)是決定整個系統上限的最關鍵音素。 就好像大師手中的那把Stradivari名琴,沒有那把Stradivari名琴,再好的錄音和回放都失去靈魂。

K DAC是桌面小型系統的核心,是Key Point, 是關鍵。

What is a K DAC?

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 color 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 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.

For headphone listeners, combine the K DAC with their matching Broadway Balanced headphone amplifier for a dynamic and powerful musical presentation for one.
