The KEYSION dual-chip dongle pairs a Cirrus Logic CS43198 DAC with a CT7601 front-end to support DSD256 and 32-bit/768kHz decoding and ships as a compact USB-C dongle form factor. It delivers true high-resolution decoding and pocketable portability, but reviewers and measurements for CS431xx-based designs warn of a DRE-related "Cirrus hump" distortion and undocumented DRE behavior that can cause subtle audible artifacts unless firmware or chip behavior is addressed.
For portable listeners who want flagship CS43198 decoding and DSD/768kHz support; avoid if you need guaranteed DRE-free, measurement-verified neutrality.
