Magico A5 (ordered) or S5mkII

Hello,

I have a pair of the A5's on order but am able to get the S5s instead. I am just wondering if anyone had experience with both and what their thoughts are? I know that the A5 is newer speaker and I am not sure if it would make a lot more sense to get the S5 from the preformance standpoint. I have never owned Magicos, but now that I can I am very excited for either of these 2 Speakers. 

Thank you
