iFi Audio Mercury 3.0 USB Cable
It comes in a substantial box with the usual fFi logo embossed on it. It is relatively easy to open. Just slide out the enclosed box and open it. You will find everything wrapped for protection; The anti-scratch wrapping required the use of a knife for these old hands. Those of normal dexterity should have no problem. You don't want to mar the excellent finish.
Enclosed are the cables in a black oversized velvety pouch, warranty card and minimal instructions. An unexpected plus was also included. Previously I lamented there was no cable include in the above combo for attachment to a smartphone. I would not call it free. Let's just say one is included at no additional cost. I had purchased one previously for use with the Hip-Dac.
Normally I would say cables are plug and play. I found one you tube review on this cable. I deemed it not very useful as it was in a foreign language. Because there is more to this cable than just wire there is something to explain. As I learn more, I will post it here.
For now, the cable is installed and being burned in.
Note: One annoying thing. When I plug the cable in it mutes the computer speaker. That's actually a good thing. But it necessitates that I disconnect the USB cord. The XDuoo mutes the computer speakers automatically and allows them to return automatically once it is turned off. That is a minor annoyance n for me because I have an all-in-one computer that sits on my desk. Quite another problem if you locate your computer under your desk. I suppose there is an easy fix that merely exposes my computer illiteracy.
Pictures to follow.
