The LA-UA1, with its diminutive footprint and cable of only 6cm length, is extremely easy to carry and use in a variety of environments. It can be used with M/X series players, BTR series Bluetooth amps, Q series DAC/amps. 

With its power reconstruction functionality and fully isolated ground and built-in power supply circuits, the LA-UA1 isolates your USB device from the noisy power supply connected at the other end by taking the power and regenerating much purer power to that USB device.
