My understanding (someone else can feel free to correct me) is that your amp can't really be too powerful for your speakers. A powerful amp is only a problem for speakers if you play them way too loud.
With an underpowered amp, you might get clipping at lower volume levels, which can damage the speakers. So the most common problem with amp/speaker pairings is that you push the amp too hard and it damages the speakers. If you have a powerful amp, you have extra headroom before clipping and can play the speakers louder, up to a point—too loud can still damage them, but the volume at which you damage them with a good amp is higher than the volume at which you damage them with a bad amp. Make sense?
In any case, my understanding is that Emotiva makes quality gear, and I think the XPA-3 should be plenty of amp for you. The only way it could be too much is if you're spending more money than you need to, but I don't really think that's the case.
As far as wall mounting goes, in my room they will have to be mounted up fairly high (7'+) so I was thinking I should get AZ and angle them.
Ah, I see. I hope my first answer didn't sound condescending.
How far away from you will the surround speaker be mounted? The farther the mount point from your seating position, the less the angle will matter. Also, you have the option of hanging the AZs "upside down" with the tweeter on the bottom, which could mitigate things (but it depends on the off-axis characteristics of the AWs).
Assuming they're far enough away, the frequency response of the AWs will change a bit from their being off axis. But the AZ frequency response will change a bit from being mounted on the wall. It's hard to say which situation would give better performance. As long as you've got some decent horizontal clearance, my pick would probably be the AWs, but that's a shot in the dark without seeing off-axis response measurements for the AZs and AWs.
Unless anybody here has a good idea, I'd suggest you contact NHT and see what they recommend. They've always been helpful when I've dealt with them (if maybe not super responsive due to being a small organization). The manual doesn't go into much detail about mounting configuration for the AW. In fact, it references more info available elsewhere, but if so, I couldn't find it.
My AZs for surround are currently on stands, but in my old apartment I had them on the wall. If I was in that situation again, I'd buy the AWs. The AZs are heavy enough that it's hard to get them mounted at an exact angle anyway. I think the AWs are just a more elegant solution, if nothing else, but it's possible the AZs could be the better sounding option.
