Help Please....Interconnects...Silver vs. Copper?


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.

I loved my 804N's ... used them with a Musical Fidelity A-20 and then Classé 101 and 151's ... so much build quality and sound that only got bigger and more profound without ever breaking down into jibberish ... those and the 803s were simply great speakers that were questioned far too much
Personally, I don't like either one (silver, copper). Check out something in the alloy realm like the Gabriels. There are others also worth an audition as well.
The difference between the materials is easy to generalize however the material does not have as big an impact as the entir package. The sound you get will depend on gauge the braid if it is braided the sheilding, the source cable quality etc. otherwise I would recommend copper but most are mediocre. Silver is expensive band not particularily the best choice for a slamming SS amp. Save your money and get Cardas Golden (fill in the blank it changes often) perfections. They are euphonic and as warm as a nice fire on a winter day.
