If you are looking for a perfect solution to increase the performance of your USB audio devices or upgrade your listening experience with your current computer-based system, the tX-USBultra is your answer.

The tX-USBultra is one of SOtM’s Ultra Series products and is designed to work with any high end USB audio device. It is a perfect companion for any DAC and the highly-regarded sMS-200 network player.

Connecting your system to a raw USB port coming directly from the main board will negatively affect the sound quality of your music, introducing unexpected sound ‘jitters’ and reducing the quality of your sound. Using their years of audio experience, SOtM has developed the tX-USBultra to become an essential system addition for computer-based audiophiles.

The tX-USBUltra is a USB audio signal regenerator – a combination of the tX-USBhubIN USB audio card and the newly upgraded sCLK-EX clock board – in a compact and specially-designed case. The clock is one of the most important factors that determines the sound quality your digital devices, and the inclusion of the clock in this unit will improve your entire system.

The tX-USBultra greatly enhances the sound quality from any server-side USB port to USB DACs by reducing the ‘jitter’ from your audio host device and presenting the analog elements as natural and dynamic. The mid-low range sounds become more detailed, with a better depth of sound that doesn’t get dragged down. The very low range is also further defined and natural, giving an overall solid performance to your listening experience.

Very easy to install; then just sit back and listen to the huge improvement to your music!
