I might add that the Avatar sounds great in Triode mode with the Europas, literature says 27watts (whatever that really means).
Here is a good article on what makes a speaker tube friendly.

I believe the Europas with their nearly flat impedance chart would qualify as quite 'tube-friendly', even though most of it is at 4ohms. This has been my experience.
The europa sounds like the off-spring between a cone and a planar speaker.
Cheers
