Up until recently, I've been using internal triwires to my Alon Circes. This means that the three legs are all carried in the same jacket of Discovery Essential cable. I was eager to see what happened if I ran a separate leg to the woofer and converted my triwire to a biwire set for the mid and tweeter. Joe at Essential loaned me a single run of Essential and I tried the combination. I really was not sure there would be much of a difference but what I noticed was 1. improved bass impact and weight - maybe even too much compared to the midrange and highs, 2. the midrange also had greater weight with piano in particular seeming more solid, and 3. the soundstage seemed a little less refined but also more three dimensional.
To alleviate the modified frequency response, I moved the speakers an extra half inch from the back wall. That was all it took to bring things into balance again. Of course, this provided an added benefit of improving the soundstage. I'm not done fiddling yet, but I can definitely see the advantages of this setup. But to be honest, I cannot say how much comes from the true biwiring of the woofer/mid-highs versus simply having more copper between my amps and the speakers.
