Power for Focal Aria 936

Hi all,
Just ordered a pair of Focal Aria 936s. Focal reports a sensitivity of 92dB, but a minimum impedance of 2.8 ohms is reported:

So how much power do I really need to optimize these speakers (large room)?
Current budget for power is only $1K, either integrated or pre + power. I'm certainly open to something 2-4 years old used.

Thanks for any suggestions/thoughts.
