I assume you meant the Cary 805ae which uses the 845 (and 211) tube.
I use that Cary on my Magnepan 3.6's from time to time (rotate it with Pass ss). The Maggies have a very flat impedance graph which tubes like. Even though the Wilsons might be more efficient they could actually be a worse load for tube amps and especially single ended ones. To best advise, the "minimum" impedance and phase angles come into play.
If your Wilsons don't have any severe impedance dips and you don't play your music very loud, I think you will like pairing.
