Focal Sopra 1 and Audio Note Kits Interstage PSE monoblocks

Can anyone advise me, from an electrical standpoint, whether the Focal Sopra 1 would be a poor choice/match for my 20 Wpc Audio Note Kits Parallel Single ended Interstage 300B monoblocks?
I know they are rated at a nominal 8 ohms but do drop lower. Sensitivity is 89db. I'm not sure of phase angle data or impedance stability. I have an opportunity to purchase a new pair at a substantial discount. My other thought is a pair of Omega XRS High Output loudspeakers. I've heard their full range drivers with whizzer cones are loved by some and unnatural to others.
Thank you for all opinions!

Thanks roxy54,
Just to clarity I already own the ANK Interstage amps and I have the opportunity to purchase a new pair of Sopra 1's. I think they'll sound great together, but I value member opinions greatly on ANK amps, Sopra 1's and the possibility of Omega loudspeakers as an alternative.  
FWIW not exactly apples to apples but I drive JMlabs (Focal) original Micro-Utopia's with a 17 watt PP class A triode wired stereo tube amp. No issues whatsoever it drives them effortlessly, not sure what the exact specs are but sensitivity is either 89 or 9db. I would imagine you'll be fine with the Sopras if you decide to go that route. No interest in AN speakers? Pretty sure a pair of either AN/K or AN/J's is in my future. I have an AN Sig-3 Dac as my source and love it. Whichever way you go good luck!
How about the interstage 300b mono, driving revel studio2?

assuming you use the stock 300b tubes, what determines if your 300b ANK interstage is 8 Watts as some refer to, or 20 Watts?

(into 8 ohms)
