Dean, you could still try the Ninja Masters out, they are not hard to install and Sean does offer a money back guarantee much like Axiom, he has a 45 day trial period. There is only one way to know for sure if you would like the modded M22 sound....

I have not heard any Focal bookshelf speakers, but if they sound anything like the Profile 918's I have heard, you are in for treat.
