A Good Match?

I've been trying to match an integrated amp with my Hales Rev. One speakers. Here's what I came up with: Yamaha A-S500.... very well reviewed. 85wpc. The Hales have sensitivity of 87db. Any opinions as to whether the Yamaha will efficiently drive the Hales? If you are familiar with my other threads on this subject, you'll know I'm on a budget regarding the amp. Thanks for any and all advice. Mike
