About the U90
The Topping U90 is a high-end USB bridge (DDC) designed to take USB audio input and distribute it to multiple digital outputs at once. It is aimed at systems that need a flexible digital hub for feeding one or more DACs, with support for configurable I2S pin definitions, ultra-low-jitter clocking, built-in USB isolation, and a 12V trigger output. It was originally positioned as a flagship-level accessory and is commonly described as discontinued by retailers that still list it as a product page.
