@suboost - I think you should get the Arias and try to just enjoy them with the rest of your setup. I would expect them to benefit from better amplification, but I'm a huge fan of maximizing your enjoyment by listening to them with your current systems and only considering an upgrade if and when you feel that there's a flaw. There's always going to be something better, so that shouldn't really be a factor. Focus on your enjoyment.
I don't know anyone personally that has a system that I like better than mine, so as long as I don't visit the local shops I can stay content with my system. I've already exceed where I ever expected to be with audio equipment, so just try to focus on the listening part of the hobby.
