概述

 

NuForce DAC-80 為領先同級產品的數位類比轉換器,並配備一組 USB 及三組 S/PDIF 輸入。

DAC-80 最多可接受四組數位輸入來源,並搭載精準的數位音量控制功能、高解析度類比 RCA 輸出級和便利的無線遙控器。

附註:Nuforce USB 音頻裝置的設計可搭配 x86 架構及 Mac OS 使用。但不支援執行 Windows 8 (RT) 的平板電腦裝置。

DAC-80 採用多項 NuForce 創新。

技術 & 工藝

低時基誤差
DAC-80 在異步模式中運作的數位輸入級,獨立於所有相關進入數位音頻串流的時序誤差之外。輸入級會同步化資料為異常穩定電路產生的內部參考時序訊號。時脈重整電路的精確度則會縮減負時序誤差 (顫動) 至接近理論限值。
 
精準的音量控制
數位 32 位元音量控制擁有精準的聲道追蹤功能。不同於以 24 或 16 位元運作的普遍數位音量控制功能,32 位元動態範圍的 DAC-80 音量控制可防止遺失任何低階解析度。
 
通透的前置擴大機
類比前置擴大機級屬於一種「極簡抽象派藝術」設計,提供的訊號路徑接近「含增益的直線」表現等級。在結合 RCA 輸出的頂尖音質和完整 4.0Vrms 訊號強度後,DAC-80 的前置擴大機部份,可確保只有最純粹的類比音樂訊號呈現在您的前置擴大機。
 
無向上取樣
24 位元、192kHz DAC 級能精準的轉換數位音頻資料回原始取樣率的類比訊號。不再採用任何向上取樣或其他有問題的資料處理方式。
   
*在首次開啟期間,若在播放 CD/曲目同時開啟 DAC80 電源並自動設定,可能會出現短暫低音量的「吵雜音樂」約 2 秒。

Technically and sonically NuForce delivers a really nice team here.  High resolution processing of various digital sources, combined with a good performance of the amp. "
Excellent sound and build quality.”
“Flexible utility piece that fits anywhere two-channel stereo digital audio decoding is required. "
Winner of the 2016 the absolute sound Editor´s Choice Awards:
"NuForce’s entry at this hotly contested price point delivers excellent sound combined with a useful feature set, making it one of the products that should be on anyone’s short list… "
Small device for big sound - With the digital analog converter Nuforce DAC80 and the class-D amp STA120 Optoma has succeeded in developing an audiophile symbioses. These units fit well together thanks to the space-saving format and discrete design. "
NuForce’s Class A solid-state HAP-100 headphone amplifier/ preamplifier offers serious highend performance at a modest price. Wide bandwidth, low
distortion, and low noise make for a sound that is quite detailed. "
The DAC is one of those rare digital devices that is not bright sounding, but more importantly, doesn’t overcompensate by sounding too dark, bland, or dreary. This makes it a very natural-sounding digital device, at a price where such things are all too rare. "
With the combination of DAC80 and STA120 NuForce provides a contemporary interpretation of modern HiFi. Those who are looking for space-saving model with minimalist design and with high tonal level, they will find their luck with the NuForce. "
The DAC80 is a simple to operate unit and looks worth the price tag.”
“The two (DAC80 and HA200) just worked so well in tandem with the extremely wide frequency band of the headphone amp allowing the DAC to breathe musicality "
Awarded 5/5 stars by Editor and reviewer Håvard Holmedal, who is also part of the EISA video-panel: I must say I'm a little surprised at how well designed the DAC-80 is. Of course it is not for free, and you should expect it to sound good, but I think its value for money is more than fair. "
"Powerful and defined, it gives a great listening experience and a lot of sensations of modern music.“ "
NuForce’s entry at this hotly contested price point delivers excellent sound combined with a useful feature set, making it one of the products that should be on anyone’s short list if he’s in the market for an under-$1200 USB DAC/pre. "
"Performance is excellent, connection quality and quantity are right on. It is a DAC to build a system around...it gets my full recommendation.“ "
