You'd be surprised but magic link / silver ref 2 make a nice combo. I find the AZ slvr ref 2's to be a touch hi fi sounding. Almost surreal in their clean sound. Not edgy but they present a lot of high frequency content in a demanding way. I currently use two magic links. The magics actually aren't quite as tipped up in the highs as the Pro-silway 2's I used to own. Given your list of options I'd go Sliver ref 2 / matrix ref 2 (which I've heard in combination). The matrix can be a bit grainy though but is a good choice to balance out the silver ref 2's. The magic's are a better balance than the matrix in my system.
Hope that helps
