The SotM (Sound of the music) tX-USBUltra works as a hub by receiving and distributing USB audio signals, but also regenerating the USB Audio signal with it’s super clock module the sCLK-EX.

May Park of SotM told us: “The mid-low range sounds very deep, detailed and earnest, the high range sounds, not distracting, but extremely delicate and open, and especially the very low range gives you transparency you have never heard before and gets you very natural and solid texture of performance”.

They claim that the benefits of the tX-USBUltra can be felt in any level of system, right up to the most high end, because of it’s built-in super clock, sCLK-EX, which has been developed over the last several years by the Korean brand.

The tX-USBultra would show how to upgrade the sound quality and improve the dignity of music by in-depth research into advanced audio technology
