這裡先提一下關於Aqvox 5米USB線的一些事情

Aqvox原廠Norman先生有發信給Eton，詢問線材的表現，原文如下

We would be very happy, if you find somehow someday the time to
email us just some words regarding your sonic-impressions with the
USB-cable.

Eton所給的評論如下

By the way, let me share some of my real experiences in using 5M Aqvox USB cable:

I compared 3 cables in between my MacBook and dCS Scarlatti D/D Upsampler,

1. dCS tailored made 4.5M cable
2. Berkin Gold Series 4.8M USB cable
3. AQVOX 5M USB cable

with no doubt, the AQVOX gives me the best sound quality in terms of high and low frequency extension,it has highest dynamic range but still sounds clear with details, warm but not harsh at all, especially,the authority of the deep low frequency.

It's amazing. This is the most exciting thing since I entered Computer Audio arena from traditional audio.
