Speaker Sensitivity AND Power Requirements


Hi all, I'm considering purchasing a pair of heavily discounted Wharfedale Denton Bookshelf speakers from Music Direct. They are 86 sensitivity. This is for my man cave system the center of which is a vintage Yamaha Cr420 receiver which has a 22 watts per channel power rating.  Would this be a decent match? 22 watts enough?  Thanks in advance.

Thanks guys, I think Music Direct has a pretty good return policy. Maybe I should get them and see how they work.  Not ready to replace the receiver. It's in mint condition, generally sounds pretty good, and reminds me of my start in this game. 
@zar IMO I would pick up a pair of Klipsch speakers (your choice of model since they will all work well) that way you are good to go with 22 wats per channel or any other amp.
+1 stevecham FWIW I have found that the more power and reserve you provide your speakers the better they perform (without blowing them out of course). There are exceptions to this rule, but in your case I doubt the exceptions apply. If it was me I would want 100W/channel to get everything those Denton speakers have to offer. Don't max the volume and you should be fine.
