Cables for Focal Utopia Diablo

I'm a little late to this party, but I just acquired a pair of Diablo Utopia iii's and I am running them off my Plinius SA103 with Cardas Golden Cross speaker wire. Sounds excellent! Although I have to confess to a bit of heresy: my Joseph Audio rm25XL's sounded pretty damn good for 1/3 of the price of the Diablos. The Diablos are definitely better in all ways other than bass extension, but $12K better (retail)?

I switched from the Cardas Golden Cross to a pair of MIT S3's and I have to say that after breaking them in for a couple of weeks, I prefer the MIT cables.  As usual, the differences are subtle -- better soundstage, a smoother sound, so I would consider myself an MIT convert.  The Golden Cross wire sounded good too, but I felt that the MIT was the hands down winner in my purely subjective opinion in my system.
