Amp to drive Focal Kanta 3

Hi guys I am new to Hifi speakers and I recently paid a downpayment to the dealership. I am planning to get the Focal kanta 3 driven by devialet expert 200. I auditioned it with the ps audio m700, and honestly I didn’t hear much difference(maybe bcs of the room?), and was willing to go the cheaper route(m700), but my dad leaned towards the devialet due to “less clutter” not for the sound. Anyways I am not a 100% on the amps driving them, and I am open to suggestions. 

I have also listened to other speakers like the kef ls50w, bowers and wilkins 804, 803d3 driven by audiolab8300xp, revel ultima studio2 driven by mark levinson 532h(this was the best sounding to me and my dad) however they were a tiny bit more expensive than the focals. I couldnt push my dads budget any more since I have already more than doubled his intial budget. Anyways I might as well rant here, I asked for an audition on the kef reference 3 on the dealer and sadly they were not entertaining me so yeah I left. For the bowers on the other hand at first they were entertaining me but I guess they got tired and thought that my family didn’t have the dough HAHAHAHA and stopped entertaining my inquiries about prices. I wanted to try the 803 d3 with the michi s5 but yeah they didn’t bother talking to me anymore. The best of the bunch was the revel ultima studio 2 the “airiness” and imaging of that speaker was amazing, heck even my dad who was laughing at me when I was describing the sound that hi fi speaker makes were impressed and said it was like the singers were inside the room. Anyways I chosed the Kanta 3 for the wider soundstage, but damn I still miss the “airiness” and the bass of the revel.

Anyways I would really appreciate any suggestions just not Mcintosh amps pls since they don’t even bother answering my enquiries. My room is 13x4m thats why I wanted a wide soundstage. Would the devialet expert 200 be a good pair with those? My fear is that I haven’t listened to a lot of amps paired with kanta 3 yet to know it’s full potential. Also I can’t push the budget anymore, and I would not be able to upgrade anymore. Any amps that have good synergy with the kanta 3?
