RUT 1K
USB terminator

RUT-1K is designed to eliminate high-frequency noise. It has the form of a plug plugged into an unused type A USB port. In a small housing there are materials used in other products of this manufacturer, RCA and XLR plugs. So we should expect that in the RUT-1K we will find dark rock crystal and a mixture of silk, quartz and other minerals. Since this is the version with the letter “K” at the end, it means that the inside has been painted with a solution containing Kiyoh-stone, a rare earth element whose main ingredient is aluminum silicate.

Plugging the RUT-1K into the USB port of the Mytek Brooklyn Bridge file player brings subtle changes. It’s not like everything is suddenly better and we buy this “plug” right away. After some time, however, it becomes clear that even such subtle changes are valuable and in the case of files can be even crucial. It improves the resolution of the smallest signals. This gives more natural space and deeper vocals. Without the RUT-1K, the sound slightly “collapses” towards the center, and the vocals sound more “hi-fi”, i.e. less natural, not so soft.

The timbre almost does not change, but it seems to us that with the “plug” it is smoother, and our attention is focused more on the midrange. These changes are not quantitatively large, but qualitatively they are valuable. You can live without RUT-1K and nothing bad will happen to your files. However, if we plug it into the USB socket and leave it there for some time, just listening to music, removing it will leave a slight “sediment” of dissatisfaction.
