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!

After discussing Roberts speakers with Jond in my last post, I checked AG's listings just out of curiosity. There's a pair of Signature 3's listed for $750, and they look close to new. If anyone needs speakers, and is willing to take a chance on something they've never heard, this is the speaker. A new speaker like this in 2015 dollars would probably sell for at least 10k.
Zd I wanted to look at those speakers and I can't find the listing your talking about. Do you have a link? Thanks.

Here's the listing ID and the web page address.
Thanks I didn't realize they were called Unity Audio. Pretty cool looking but sadly local pickup only. A good deal for someone in FL however.
