The metalurgy lessons are very interesting but the proof is in the listening. I have rewired my LS, KG4's, KG3.5's and every other speaker that I have owned and have found improvments with all of them. Some more than others however. I think the biggest difference was with the KG4's and mostly with the tightness of the base. I truely believe that replacing the low quality hook-up wire (used in maufactured speakers for cost saving purposes)can make any speaker sound better. My favorite is the Monster XP because of its flexability and its easy to work with. I have used RS/UltraLink interconnect for HF drivers and find noticable improvment also.
Just my 2 cents worth.
