SOtM tX-USBexp is the world’s first PCI express USB 3.0 host interface card designed to perform the ultimate USB audio playback.

If you want to use a PC as a hi-end audio source device via a USB connection, various types of noise should be blocked from the inside the digital devices. To reduce such noise, the tX-USBexp has been designed with the special filter circuits, an Ultra low-noise Voltage regulator, and an ultra-low jitter clock equipped.

The tX-USBexp can be powered from an external power input connector and the sPS-500 is the one that matches best with the tX-USBexp.
