I use an Anthem 520. It was paired with an older Parasound channel power amp and the front speakers are Silverline Panatellas. The Parasound gave up the ghost a few months ago and I was assured that the Anthem should be able to drive everything (the power amp was added to help a previous Denon AVR which definitely could not drive the system). I do seem to miss the grunt of the power amp and am thinking of adding a new one.
I mention this because someone up thread mentioned that the Focals are a difficult load. I should mention that I have a second HT system in the home, different speakers, same Anthem 520 that drives everything well. I value the Anthem Room correction quite a bit.
If I was the OP I would seriously consider a used AVR because there is a lot of inexpensive choice out there combined with a 5 channel power amp with some grunt.
