I recently biwired my front floorstanding speakers to my receiver. The receiver only has two terminals per speaker, but when I twisted the 4 cable ends together in order to merge 4 cable ends into two, they would not fit in the little hole under the plastic hood. My solution was to put the ends into different sides of the holes, as I've illustrated here (the black lines repesent the metal part of the output): f1 .pg .photos .yahoo .com/ ph/ eu...4& .dnm=5a71 .jpg (Paste into another browser window and remove the gaps) Upon testing, I was disappointed to hear a descrease in sound quality. There seems to be a problem with midrange frequencies. Orchestral strings are half drowned out and no longer fill the room when they are supposed to get loud. Also the sound is uneven. Sometimes there will be a noticeable dip in the volume of an instrument or it will shift from one side to the other. Could this be caused by the way I've wired the cables to the receiver terminals? For example if the tips of the cable ends are touching the other cable?
