Cardas Interconnect Upgrade??????

Currently I am using all Cardas Crosslink interconnects from my Rotel RSP-1066 processor, Rotel RMB-1075 5 channel amp, Rotel RDV-1080 DVD and Rotel 991 AE CD Player. I also run the entire Vandersteen speaker
set-up for 5.1 home theater. Now I would like to relocate the processor, but this would mean I would have to change out my 1 and 1.5 Meter Crosslinks for 2.0 M cables.
But to the meat of my question, can anyone tell me for the price range of equipment I have. Would I be investing in a noticable difference if I was to change at least the Right and Left front channels to say the Cardas Cross interconnect, if not all the front three speakers?
I am running the Vandersteen 2CE Signature Series for fronts and the VCC-1 for a Center. When I purchased the cables from my local dealer he told me that if I was to upgrade interconnects that the difference would be minimal.
So any suggestions??? then at least the Quadlink 5-c's or even the Cross Series maybe?
I would appreciate all opinions in my quest to optimize my system within a reasonable monetary figure.
Thank You,
Your dealer is wrong. I have one pair each of all of the Cardas line and there's a definite difference as you go "up the line". The Quadlink 5C's would be a good upgrade. I don't sell Cardas but I can point you in the right direction for good prices.
Forgot to mention: the "right direction" is a regular seller here on Audiogon...VERY dependable and an asset to this website.
going up the line in cardas ( outside of the neutral series)is a step toward warmer and warmer cables. the golden cross was probley the warmest cable i have ever heard before in my life.

alot would depend where you want to take sound. most cables fall into two camps:

warm/body/bloom - cardas
transparent/imaging/bass- xlo

i would suggest taking as many cables as you can home and listen for yourself. try changing both sets of ic's with mixing and matching.

hope that helps !!
