Wilson Maxx 2 vs Sonus Faber Stradivari

I listened to the Maxx and SF Elipsa before, but not to the SF Strad. However competition for the Maxx is probably the Strad and definitely not Elipsa. What I like about Sonus Faber design is the soulfulness. The Strad also has 4-ohm impedance with 92 dB sensitivity, meaning no need to replace my Pass XA60.5 which I very and very much enjoy. Does anybody have comment on those 2 speakers as to price to performance advantage? Secondly would it be too much to drive pretty Strad with the more gentle side of amplification such as Pass Labs design and Acoustic Zen Satori speaker cable.
