The article on speaker cables on the home page of Stereophile.com is interesting. When I decided to upgrade my system I did upgrade my speaker cable to the Monster Z3 which actually I am very happy with. At $200 for the pair (6') it was about the top of what I wanted to spend.
Now to me the amount you spend on speaker cables is should be in proporation to the amount you spend on your system. My system (Arcam Solo, Paradigm 100) was less than $5K so I could not justify spending a lot on cables. I will throw this up to the group...can you really hear the difference with high end speaker cables vs. those that cost less? What do you recommend in the $200 range and higher?
