The answer is yes, the Denon will easily drive those Klipsch speakers. They are particularly easy to drive. 150w of power is the max that can be sent to those speakers without damaging them. They can be driven to deafing levels with 25w of power.

My question is, have you listened to the klipsch speakers? I went though this exercise a few years back and from research I settled on Klipsch Reference. Once I listened to them I opted for another brand.

Klipsch sound profile tends to be a bit bright. Audyssey in your receiver will help adress this but it won’t change the fundamental character of the speaker. Klipsch sells a lot of speakers and many people love them but I strongly suggest you hear them before you buy.
