The new KingRex UC192 is described as "a very high-quality computer audio transport interface for those wishing to stream high-resolution files to an existing DAC. The UC192 can transfer from PC or Mac at 16/44.1 or up to 32/192 through its S/PDIF & I-squared-S outputs. The UC192 runs isochronous with an adaptive clock generator to auto sync with the host. The master clock generator is a classy 1ppm TCXO unit with proprietary low-jitter drivers for Windows & Mac. Kernel streaming, Direct Sound, ASIO4ALL and WASAPI are all supported and run smoothly. The UC192 is housed in an oval cross-section aluminum case with black hairbrush polish. It measures 88 x 82 x 24mm."
