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.

I recently bought a pair of 936, amp budget is also 1k+. Here's my short list:

1, Vincent SP 331, 150w 8 ohm/300w 4 ohm, 2 ohm stable
2, Odyssey Khartago, 110w 8 ohm, 2 ohm stable. Not sure if I should be getting the Plus or Extreme mod.
3, Parasound A23, 125w 8 ohm/200w 4 ohm, can do 2 ohm, but will clip at certain level according to a test report I found online.
4, Parasound 2250 v2, 275w 8 ohm/400w 4 ohm /400w 2 ohm
