The best is JPS or Miller Sound. I have used Monster Sigma. Got rid of them after Miller Sound which is a cheaper version of JPS. No cable better to my ears unless you get into thousands of dollars for exotic cables.
Which is the best cable for Martin-Logan?
I use martin-logan Quest z with monster-cabe powerline 2 plus (krell power,mark levinson pre..etc) but my friends of Audio club say monster is not good for my system and Transparentcable is best for mine... unfortunately..it's very expensive... and they recommand MIT , Cardas well, I dont know much about cables. Must I change speaker cables to get clear sound?
