• DYNAUDIO DAC9 晶體數位類比轉換器 規格表

DAC9
Tube Digital to Analog Converter

DAC9 數位類比轉換器配備了最先進的真空管技術，能解碼幾乎現今所有的格式。五種連線的方式：USB, RCA, BNC, AES/EBU, 和光纖連線，能滿足所有數位訊源的連線需求。

採用Quad DAC，提供了非常平衡的數位訊號、寬廣的動態範圍，可以解碼384 kHz的高清數位音樂光碟，至自然DSD取樣。一對6H30真空管是類比迴路的心臟。提供平衡與非平衡的連接頭的輸出連線選項。可調整數位訊號的自然取樣升頻及濾波。

Foundation Series
Audio Research非常榮幸能推出 Foundation系列。出自享譽盛名的Reference系列製造工程團隊與設計師，Foundation家族的真空管的構造是以「令人驚豔的音樂體驗」為目的而製造，空間感、動態細節絕佳，同時營造最真實的音樂環境。

最早的三個組成包含了LS28前級擴大機、PH9唱頭放大機和DAC9數位類比轉換器。將會有新的擴大機及其他產品陸續推出，來完整這個系列。全部的型號都將有黑色及原色銀色可選擇，也都會有屬於自己的金屬遙控器。

自從1970年起，Audio Research的正字標記已經不僅僅是標榜HD而已，更是我們生產所有商品的最高準則。Foundation系列延續了這個熱情與哲學，提供令聽者驚豔的聲音、價值與無可取代的長期支援。

Digital that sounds like analog
Digital advances quickly and Audio Research continues to stay at the performance forefront.
Our perspective and love for analog reproduction helps make our digital components sound superior musically. The DAC9 is a vacuum-tube analog section combined with the latest digital design, capable of decoding DSD music files and PCM files up to 384kHz.

Selectable digital filters & quad D-A converters
Audio Research designed two separate data paths to the DAC9’s D-A converters: one for PCM files, and another to handle serial DSD files at 1x and 2x DSD clock rates. This assures proper integer decoding eliminating interpolation distortion errors that degrade sonic purity. Native sample-rate upsampling is available for all inputs, up to 384kHz for non-DSD (PCM) music files.
Selectable digital filters are available for customization. An asynchronous USB input, along with four galvanically isolated SPDIF inputs, assures all of your digital sources will integrate with the DAC9. We pioneered using quad D-A converters, with each channel using dual stereo DACs running in mono to increase dynamic range and lower the noise floor.

The digital side mates to a vacuum-tube analog section that uses a pair of 6H30 dual triode tubes. The DAC9 is a balanced design with a Class-A, zero feedback analog section with no capacitive coupling.
Like other products that have preceded it, the DAC9 combines remarkable resolution with relaxed musicality. Audio Research’s sonic legacy—clarity, dynamics, dimensionality, and musical authority—are obvious and thoroughly engaging.

After more than 50 years, our focus remains the advancement of the state-of-the-art in music reproduction. Every component is meticulously hand-crafted and personally auditioned befor it leaves our Minnesota facility.
Our attention to detail, customer service, and product support create unprecedented value. An Audio Research component is more than a purchase, it is an investment.
