AudioAero Capitale II vs Muscial Fidelity Tri-Vist

aside from the trivista offering SACD (which at this point I am ambivalent about), what say you about comparing these? Forget about the built-in preamp of the AA (I intent on having a separate pre in either case).

Assuming they are both plugged into a top-notch preamp, both playing redbook CD - which would you prefer and why?
It seems they both have very similar qualities....
