Question

I read it on the manual, section 5:

"Up to four Quantum interfaces can be aggregated together for combined 104 inputs and 128 outputs at 44.1 and 48 kHz"

I was going to get a 2nd quantum but I usually record/work at 96Khz.

Answer 1

They are only saying 44 and 48 if you add 2 units to each quantum.   Daisy chain 4 quantums and get 32 inputs at 192khz.
