Previously, I had an external hard drive with my music library directly connected to the rear USB port of my Denon amplifier, but as I regularly expand my music library I had of course constantly separate the hard drive from the system and reconnect again. This was doubly annoying, first, it has always been quite a Gefrickel pull the hard drive from the hard to reach port from and above all to reconnect, secondly, the terminal of the amplifier has suffered over time under constant pulling and connecting the hard drive. More or less by chance I came across the USB extension cable from Ugreen and thus the solution to my problems. After the cable was once connected to the rear USB port of the amplifier, accounted for the annoying Gefrickel and I can always quickly and easily separate the hard drive from my system and re-connect and I can the hard disk due to the length of the cable now quietly in the Rack hide. The cable Ugreen typically has a excellent quality, due to the gold-plated USB 3.0 ports can be transmitted not only fast but loss and especially stöhrungsfrei data.
