Your expertise, please

I'm looking for more transparency, and to solidify & push back the soundstage. It seemed that my speaker wires could be the weakest link. I'm thinking about the Red Dawn II cable because it should increase transparency while I maintain the warmth running tubes pre-amp and amp. Would it help with the soundstage issue? The stage is a little too forward right now, I've tried repositioning the speakers. Are there other cables u would consider? How are the Synergistics with active shielding? (real or gimmick?)
