I see that you own a sweet pair of CS 2.4 plus Outriggers Speakers!
Best practice, stick with a Copper cable. No Silver. Audioquest (AQ), Cardas, Kimber Kable, Purist Audio Designs, Transparent and Wireworld, are all sonic matches. The key is to dial-in said Cables to your Power Amp.
Which brand are you enjoying?
Happy Listening!
