It really doesn't matter what other people think of your purchases as long as you feel they are provided good sound and value. As Soix says above, cabling is very system dependent. Hook-up with a good local dealer or someone like the Cable Co. who will let you at home demo a number of different products. Some will probably work better than others and its possible that you might come across a specific line that works magic on your system. I recommend that whatever you pick, stay with the same manufacturer for both interconnects and speaker cables. There are some synergistic advantages.
