" Do you have any more suggestions on the amplifier?"
Did you have something else in mind? The Ayre has a very good price/performance ratio. You can definitely use something else, but you just need to be careful with regards to your other components gain. The Cubs are something like 95db, and like any high efficient speaker, they're not forgiving when it comes to gain. If you're not careful, you can get a hiss.
If the Ayre is too much, maybe look at the Parasound Halo integrated. It goes for around $2500 and it has a dac. The Halo gear has a good track record when being paired with Wilson. Also, having the dac, preamp and amp in one box should eliminate any chance of gain issues. You probably won't like it as much as an Ayre, but it should still be a huge upgrade from what you have now.
