Speaker Cables for Sonus Faber Olympica III

Does anyone have any suggestions for speaker cables for Sonus Faber Olympica III? I've read some reviews online and it seems very difficult to purchase cables without auditioning, but this is my situation. I really want to bring out the best of the Olympica III's, the soundstage, midrange warmth, instrument/vocal placement, and overall seductiveness of the speakers. I own a Primaluna Dialgoue HP Integrated Tube Amp as well. I am looking to stay at $2,000 - $3,000 new or used. I've had recommendations from various dealers pushing mainly Transparent Audio cables or Nordsot cables, and have no idea who to believe or where to start. I am an audiophile newbie and building my system from scratch. Thanks for your help!
