PreSonus Quantum HD 2
A pro-tier USB-C interface whose headline features are 32-bit-float capture, MAX-HD preamps, and ADAT expansion across 24 outputs. It's built for quality-focused producers who want clean conversion now and room to grow. Out of the box it has only two mic preamps, so anyone tracking many mics at once will need to expand via ADAT rather than rely on it alone.
