Would this be an upgrade?

Personally I would be more intent on upgrading an interconnect than ,what looks to me like a sideways speaker cable move..In my world I have found that speaker cables have less impact than an Interconnect or Power cord..I have had better luck with upgrading Equipment footers than speaker cables..I just don't think what your proposing to do will reap much positive impact..Thats just what my gut tells me...

I vote for Cardas

I also agree that the Cardas would be a step up from the Monster.

I used the Quadlink speaker cable for a few years and always enjoyed the sound it gave me.
