The Matrix has a dual AD1955 chip and like others here boasts an independent internal clock that aims to minimise the jitter introduced to your files on their way to the DAC.
The Mini i can handle 24-bit 192kHz music via coaxial and optical inputs, while the USB input maxes out at 48kHz, as is not uncommon.
If you like the flexibility, it's well worth a look.
