I am now running a Plinius 9100 to B&W Nautilus 804s with Tara speaker cable. My source is an Esoteric DV-50. I ran Tara RSC Air 2 XLR from the Esoteric to my BAT VK-31. I have downgraded to a Plinius 9100, and I need RCAs. Any advise...PLEASE... I want to maximize my potential here within the $200 range. I have been looking at the Black Dragon, Morrow Audio, and DH Labs BL1 & Revelation. I am not sure what silver will do to my sound?!?! I have heard silver and copper sound different. Any help would be appreciated. Thank you.
