is a high-performance USB-C DAC chip from Conexant, widely used in budget "Hi-Fi" dongles. While it offers impressive specs like 32-bit/384kHz sampling and >128dB SNR, users frequently report issues with the device becoming physically hot during use, particularly when paired with Windows systems or high-resolution formats like DSD. 1.
