SOtM Launches the tX-USBultra USB Hub & Regenerator

Award-winning Korean manufacturer SOtM are set to launch a few new products this year, starting with the tX-USBultra. The component is a two port USB hub and regenerator designed for the best USB audio performance.

SOtM have specially designed the tX-USBultra to provide ultra-low jitter solutions for computer audiophiles. The component improves noise filtering and timing before it reaches the DAC or other output source for a clearer sound.

The tX-USBultra regenerates USB signals using SOtM’s high-performance super clock module, the sCLK-EX. This internal module provides a superior sound upgrade to all computer hi-fi systems. The sCLK-EX module can also synchronise with high precision clocks such as the rubidium clock.

SOtM’s tx-USBultra will be available in the UK soon from Elite Audio and is set to retail at £990.

The Korean manufacturers will also be attending this year’s High End Show in Munich, along with the tX-USBultra USB Hub as well as other products from their range of upcoming new components.
