V-LINK 數碼訊號轉換器

$1,380

The Musical Fidelity V-Link is a simple device that does one thing, but does it unerringly well. It connects to your PC or Mac by USB 2.0 on one end, and offers up two digital audio interfaces on the other: RCA coaxial and Toslink optical. To overcome PC jitter issues, it uses asynchronous-mode USB transfer.

In short, it’s the missing link between any computer that can host and play digital music files; and any hi-fi system with a digital audio input.

The Musical Fidelity V-Link is a simple black-painted aluminium box, with no on/off switch nor other buttonry. Its energy draw for the few chips inside is minimal, and so takes its power from the 5V USB bus.

Once connected to a PC, it automatically appears as a sound device, requiring no proprietary drivers that can potentially destabilise your system. And in another blow to the similarly specified and priced M2Tech HiFace, it introduces no latency in its decode chain, so is happy to work in perfect synchronisation with film and video material too.

Musical Fidelity cites lab measurements that suggest the unit introduces no jitter of its own whatsoever, the only new traces on the graph plots being those inherent to the measurement equipment itself. And listening to music through the V-Link, we heard what may be the closest approach to the original (PC) sound.

iPurifier2 USB訊號淨化器

$950

ifi iPurifier USB數碼淨化器傳統USB線的傳輸標準,不能傳送高品質的音頻信號。因為傳統的USB線是將USB電源線、USB信號線和USB地回路線集中在一條線內,在傳輸高品質音頻信號時,相當於把高品質的音頻信號放置在有嘈雜噪聲的電源線旁邊,所以傳輸出來的高品質音頻信號會大打折扣。 因此EMI高頻噪聲的問題在USB傳輸過程中不可避免,其特點是尖銳、刺耳的聲音。

iFi iPurifier主要功能就是過濾和清除一切幹擾信號,保障純凈的音頻信號輸送給DAC。 這是一個很特殊的電路設計,它能很完美的恢覆音頻信號並且消除數碼聲,讓聲音栩栩如生的呈現在你的耳旁。

iFi iPurifier能夠支持PCM/DSD/DXD等格式的音樂。計算機的音頻電路有一個令人厭惡的噪聲,那就是EMI噪聲。該噪聲是由分散在計算機內部的通用開關電源部分靠近音頻線路而產生的。在無音樂輸出或者切換音樂時,表現最為明顯。 另外, 一般的USB信號還會不平衡和帶有直流偏移。
直接從計算機輸出音頻信號到DAC,EMI噪聲通常是39dB。而使用iFi iPurifer之後,輸入到DAC的EMI噪聲為34dB,降低了5dB,並消除了不平衡和任何的直流偏移。這對整個系統而言是難能可貴的。
