Audioquest or Nordost for speaker cable

@soix - great question. Before I was using Cardas Clear Cynus. Those are great cables and I still have them. The Cerious cables have so much better clarity, detail, and expanded soundstage. Not to mention the noise floor was greatly reduced. I can’t say enough about their cables. I also have a Lumniscate PC and love it too. I’m going to replace my Cardas Clear Cygnus XLRs with the Lumniscate or the Matrix after I replace my speakers in the next month or so. Reach out to Bob who is the engineer. He is the nicest guy you’ll ever meet. 
 

Also, there are tons of discussions here on Cerious cables. 

I hate to add another option but Cerious Tech makes speaker cables that far exceed their price point. Cerious Tech Lumniscate line gets out of the way and allows you to hear your components and as a result the music. I highly recommend doing your research on them before making a decision.
