What should be removed

Get rid of all 3 and buy something like an Ayre AX-7. I have a pair of Cubs myself that I use in a 2nd system. They're pretty good speakers. But if you don't pair them with modern, high quality electronics, you'll never hear them at full potential. 

" 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.

I have a pair of Cubs myself and have no issues driving them. Actually, they're very easy. For the last several years I've been using them with my VAC 30/30 tube amp. (30 watts/ch). Its a great sounding combo, and the amp doesn't strain at all. 

I have some high quality SS amps just laying around that I could put in the system at any time. After comparing them side by side, I still prefer the VAC. If we were talking about some of the bigger Wilson's, then I would agree on needing more power.

What brands do you have access to in Sweden? I know you can get Primare. They make excellent products that should work really well with your speakers. Very underrated company. (At least hear in the US). YBA would also be a very good match.
