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.

Thanks for the comments so far: Parasound A23, as well as older HCA-2200 are in the price range. Obviously a bit concerned about helomech's comments about heat (though the HCA-2200 pushes 750 WPC at 4 Ohms...
Not familiar with Schmitt's. Good reviews, very intriguing. Anyone with experience out there with these? Sound quality?
I'm always nervous about "audiophile quality at mid-fi prices. Emotiva is in that category as well. Locally I found a Parasound HCA1000a and Emotiva USP-1 for $300 apiece.
Thoughts on those and the above??
I also see an Adcom GFA-555se for $650 (purchased in 2015), and a pair of Emotiva XPA-1L mono blocks for $700 on Audiogon right now.
Any experience with those?

So I've done some homework on the Schiit Vidar. One review mentions that low impedance at higher volume (which I do enjoy, especially as the ears age...) may trip the protection circuit.  http://www.ilounge.com/index.php/reviews/entry/schiit-vidar-power-amplifier
That makes me nervous, even though sure seems like you get a lot for your money. Anyone out there using the Vidar to drive the 936s?
Any thoughts on the Adcom or Emotive options above, or other suggestions?
